    To produce ginkgolides from callus cultures of icho, (Ginkgo biloba L.) seeds, calluses were induced by use of three mediums, namely MS (Murashige and Skoog), SH (Schenk and Hildebrandt) and B5 (Gamborg B5). The MS medium was found to be best for production of ginkgolides as well as for callus growth. High-performance liquid chromatographic analysis of the extractives of calluses revealed that the calluses produced ginkgolides A and B which are known as antagonist to the platelet-activating factor. The content of ginkgolides A and B in the calluses was 0.0042% and 0.0090%, respectively, based on dry weight, when the calluses were incubated at 25degreesC in the dark. The calluses of icho seeds cultured in the dark produced 75% and 97% of ginkgolides A and B, respectively, compared to those of the intact plant.
    The content of ginkgolides A and B in the calluses was increased a maximum of 3.5 and 5.9 times, respectively, compared to that of the intact plant, when chito-oligosaccharides were added to the calluses as elicitors. When geranylgeraniol as a biogenetic precursor of ginkgolides was added to the calluses, the content of ginkgolides A and B was increased a maximum of. 56 and 14.3 times, respectively, to that of the intact plant.

    The effect of plant hormones on the induction of callus from seeds of Icho, Ginkgo biloba L., in relation to storage periods of the seeds was investigated. When a combination of 1-naphthaleneacetic acid (NAA) 1.0 mg/L and kinetin 1.0 mg/L was added to Murashige-Skoog (MS) medium on induction of callus from fresh icho seeds, the maximum amount of calluses was obtained. On the other hand, when a combination of NAA 2.0 mg/L and kinetin 5.0 mg/L was added to MS medium on induction of callus from icho seeds stored for eight months, the maximum amount of calluses was also obtained. The results showed that as the storage period of icho seeds increased, the productivity of ginkgolides in the calluses induced from the seeds was reduced. However, the productivity of ginkgolides in the calluses induced from both fresh icho seeds and those stored for eight months was enhanced. Furthermore, we found that the content of zeatin, a natural plant hormone, in the seeds decreased during the storage period.

    Antifungal activities of four flavonoids [sciadopitysin (1). ginkgetin (2), isorhamnetin (3), and quercetin (4)] and taxinine (5) (a taxane-type diterpenoid) isolated from the leaves of Ichii ( Taxus cuspidata Sieb. et Zucc.) and Kyaraboku (T. cuspidata Sieb. et Zucc. var, nana Rehder) against Cochliobolus miyabeanus and Altenaria kikuchiana, plant pathogenic fungi, were measured for utilization of the extractives from the genus Taxus trees. Sciadopitysin (1), quercetin (4), and taxinine (5) showed antifungal activity againt C. miyabeanus. To find more active compounds than taxinen (5), seven taxinine derivatives 6-12 were prepared from taxinine, and their antifungal activities against the two fungi were measured. Amoung the seven derivatives bisdeacetyltaxinine (6), isopropylidenebisdeacetyltaxinine (7), isopropylidenetrideacetyltaxinine (8),and taxinine epoxide (12) showed almost the same activities as that of taxinine against C.miyabeanus. On the contrary, antifungal activities of the five compounds 1-5 isolated from the leaves and the seven taxinine derivatives 6-12 against A. kikuchiana were weak, and the activities were about from one-half to one-eighth of those against C.,miyabeanus.
    In addition, the effects of substituent groups of taxinine and flavonoids on the antifungal activities against the two fungi are discussed.

    Treatment of the pulps prepared from non-woody plants, abaca and kenaf with two commercially available pectinases, pectinase PL[AMANO] and Ultrazym containing CMC-ase, xylanase and beta-glucosidase was conducted to investigate the effect of the pulp properties on the pectinases treatment. We found that large amounts of parenchyma cells in the both kenaf and abaca pulps were removed by the two pectinases treatments. Seventy to almost one hundred percent of the parenchyma cells could be removed from the both pulps by the 24 hours' treatment. However, the weights of the kenaf and abaca pulps treated with the pectinases were decreased by 4 to 28 %, especially the loss of the weights was increased with increase in amounts of CMC-ase, beta-gulucosidase and xylanase coexisted in the pectinases. The water retention values of the kenaf and abaca pulps were decreased by 28 to 80 % by the treatment with pectinase PL [AMANO]. On contrary, the values of the kenaf pulps were increased by 10 to 53 % by the treatments with Ultrazym. The physical properties of the abaca pulps treated with pectinase PL [AMANO] generally made little difference from those of the untreated pulps. However, the breaking length in the physical properties of the abaca pulps was improved by 5 to 36% by the treatment with the pectinase. The properties of the kenaf pulps treated with the pectinase were lowered in those of the untreated pulps.

    Calli were induced from leaves of young trees of icho, Ginkgo biloba L., on Murashige and Skoog medium, supplemented with 2,4-dichlorophenoxyacetic acid and kinetin, and subcultured on the same medium. High-performance liquid chromatographic analyses of the extractives of calli revealed that they produced Ginkgolides A and B that are known as antagonists to the platelet-activating factor. The contents of Ginkgolides A and B in the calli were 0.0049% and 0.0180%, respectively, of the dry weight when the calli were incubated at 25 degrees C in light. On the other hand, the contents of Ginkgolides A and B in the calli incubated at 25 degrees C in the dark were 0.0017% and 0.0094%, respectively, of dry weight. The calli cultures of the leaves of icho in the dark and light produced from 23 to 67% and from 57 to 110% of Ginkgolides A and B, respectively, of those of the leaves of the intact plants.
    The contents of Ginkgolides A and B in the calli were increased 1.2 and 5.9 times in maximum values, respectively, to those of the leaves of the intact plants when the chito-oligosaccharides functioning as elicitors were added to the calli. When geranylgeraniol as a biogenetic precursor of ginkgolides was added to the calli, the contents of Ginkgolides A and B in the calli were inceased 1.2 and 3.0 times, respectively, in maximum values, of those of the leaves of the intact plants.

    機械パルプの光による色戻りにおよぼすフェノール性水酸基の影響について検討した。機械パルプをアセチル化すると, 色戻りは抑制された。未漂白GP (UGP), 未漂白TMP (UTMP) ではパルプ中のフェノール性水酸基が約11%アセチル基で保護されることにより, 色戻りは完全に抑制された。一方, 漂白GP (BGP), 漂白TMP (BTMP) ではパルプ中のフェノール性水酸基が各々16%, 29%アセチル化された場合にその色戻りが完全に抑制されることがわかった。GPおよびTMPいずれのパルプでも未漂白と漂白済みパルプでのこの差は, 各々のパルプの製造条件の違いに基づくリグニンの変質の程度とH2O2漂白によるパルプ中のリグニンの変質 (例えば, キノン, ハイドロキノンの生成等) に起因しているものと考えられる。しかし, 内容については更なる検討が必要と考えられる。UGP, BGP, UTMPおよびBTMPをアセチル化したパルプの差反射率は, アセチル化によりコントロールのそれよりも低下した。色戻りに影響すると言われている420-440nm付近のキノンの吸収が未処理 (コントロール) のそれに比べ大きく低下した場合には, 色戻りが大幅に抑制されるものと考えられた。<BR>アセチル化パルプをPTC併用KBH4還元した場合には, アセチル化のみを行った場合に比べ, 色戻り抑制効果の低下がみられた。これはアセチル化パルプのPTC併用KBH<SUB>4</SUB>還元時にアセチル基が一部脱アセチル化されたため, 色戻り抑制効果が低下したものと考えられた。<BR>これらの結果から, 機械パルプの光槌色にはフェノール性水酸基が大きく影響しているものと考えられた。

    The time-course of the activities of cumulative lignin peroxidase (LiP), cumulative managanase peroxidase (MnP), and cumulative laccase (Lac) from the five fungi having ability for degradation of 2,7-Dichlorodibenzo-p-dioxin (2,7-DCDD) was measured in connection with the degradation rate of 2,7 DCDD with five fungi. The activity of cumulative Lip of a fungus was higher, the degradation rate of 2,7 DCDD was higher. Correlation between the activity of cumulative Lip and the degradation rate of 2,7 DCDD was observed. However, the activities of cumulative MnP and cumulative Lac were not correlated to the degradation rate of 2,7-DCDD. From the results obtained above, we found the improved screening method of fungi having higher ability for degradation of dioxins. First, screening of fungi having ability for decolorization of dye was carried out by using Remazol brilliant blue R, a kind of dye, as an indicator. In the second screening, fungi having ability for higher activity of cumulative Lip were selected. By using this method, three fungi named 25, 65, and E having higher ability for degradation of 2,7-DCDD was obtained by the screening from natural world.

    To increase the amounts of gibberellins produced by the microbial conversion of (-)-kaurene with Gibberella fujikuroi, a screening of ten G. fujikuroi strains was conducted. The G. fujikuroi IFO 9977 strain was found to lead to the largest yields of gibberellins. The formation of gibberellins from (-)-kaurene with the IFO 9977 strain was 1.4 times larger than obtained with the IFO 30337 strain which previously was found to produce the largest conversion. The biological activities of the gibberellins from (-)-kaurene with the IFO 9977 strain, as indicated by the elongation of the second leaf sheath of dwarf rice, tan-ginbouzu (Oryza sativa L. cv.), were the most of the ten strains used. Furthermore, the effect of the substrate concentration on the formations of gibberellins also was investigated using the most active strain indicated by the screening tests. Gibberellin formations decreased with increasing substrate concentrations in the culture medium.

    The large visco-ductile compound (1), [ (alpha'',beta'-dipalmitopl) -glyceryl]-alpha- (omega-carbononadecanoyl) -alpha',beta-dipalmitoyl-glycerol, can be prepared from tripalmitin (2) and carboxylic acid (3), alpha-(omega-carboxynonadecanoyl) -alpha',beta-dipalmitoyl)-glycerol, by interesterifications with five commercial lipases in one step. The yield of the Compound 1 changed by the lipases used. The largest yield of Compound 1 was obtained in the yield of 20.1% of Compound 2 when the interesterification was conducted with lipase from Rhizopus delemar. The yield of Compound 1 obtained by the interesterfication with lipase from Mucor miehei was 18.6% and following that from R. delemar. The yields of Compound 1 with Rhizopus sp. and Aspergillus sp. lipases were 12.3% and 7.2%, respectively. The smallest yield of Compound 1 was obtained in a 2.1% yield when the interesterification was conducted with lipase from Aspergillus niger.
    The effects of the solvents, the reaction temperatures, and the added amounts of lipases in the preparation of Compound 1 by interesterifications with lipases also were investigated. The polarities of the solvents in the interesterification were greater and the yield of Compound 1 was less. The present interesterification with lipases was found to have an optimum temperature and optimum amounts of enzymes used.

    Reduction of acetophenone derivatives as a model compound for having α-carbonyl group was conducted to find out the effect of carbonyl groups, especially α-carbonyl group, in mechanical pulps on light-induced color reversion. The model compounds could not be almost reduced with potassium borohydride (KBH<SUB>4</SUB>) only, however, the reduction was effectively proceeded by addition of small amount of phase transfer catalyst (PTC). The methyl ether derivatives of acetophenones having no free phenolic hydroxyl group could be reduced with KBH<SUB>4</SUB> accompanied with PTC to the corresponding alcohols in almost quantitative yields in a short time. On the contrary, in the case of the compounds having free phenolic hydroxyl group the reaction proceeded only about 20 to 30 % on the reduction. However, the carbonyl group could be reduced about 75 to 90 % when the phenolic hydroxyl group was blocked as acetate and followed by the reduction. In addition, the reduction products were further deacetylated during the reduction to the corresponding alcohols having free phenolic hydroxyl group.<BR>Based on the results obtained from the model experiments, effect of reduction of carbonyl groups in mechanical pulps on light-induced color reversion was examined. Light-induced color reversion of groundwood pulp (GP), thermomechanical pulp (TMP), and pressurized groundwood pulp (PGW) could be depressed 33-44%, 11-19%, and 11-23%, respectively, to that of untreated pulps by pretreatment of unbleached mechanical pulps with KBH4 accompanied with PTC. And furthermore, the color reversion of GP, TMP, and PGW was also depressed 24-39%, 12-24%, and 10-26%, respectively, to that of untreated one when bleached mechanical pulps were treated with KBH4 accompanied with PTC.<BR>The results showed that the effect of carbonyl groups in GP, TMP, and PGW on light-induced color reversion could be suggested about 30 %, 15 %, and 15 %, respectively. It has been said that carbonyl groups, especially, α-carbonyl group in mechanical pulps are greatly responsible for the color reversion. From the results obtained here, however, it is considered that carbonyl groups in mechanical pulps do not contribute so greatly to the color reversion, though α-carbonyl group functions as a photosensitizer on light-induced color reversion of mechanical pulps.

    Syringylalcohol (1), alpha-methyl syringylalcohol (2), 3,4,5-trimethoxyphenyl methylcarbinol (3) were dispersed onto filter paper pulp or linter pulp, and treated, respectively, with a ceramic ball mill (CBM) or a vibration ball mill (VBM-1 or -2) under air for 1 h. Mechanical treatment of VBM-2, having the more rigid surface of linter pulp, furnished the p-carbonylphenols (5), (6), and 3,5-dimethoxy-p-benzoquinone (7). Mechanical treatments of syringylglycerol-beta-guaiacyl ether (4) with CBM, VBM, and a laboratory refiner provided alpha-(2-methoxyphenoxy)-beta-hydroxypropiosyringone (8) in the highest yield and a less yield of p-quinone derivative (7) and others as shown in TABLE 2 and FIGURE 3. When treated the resultant mixture with alkaline H2O2, the chromophore (III) can be decomposed, but remarkable amounts of the leucochromophre (IV) are produced as shown in FIGURE 4.

    Apigenin methyl ethers and amentoflavone methyl ethers could be prepared by enzymatic conversions of apigenin (flavone) and amentoflavone (bisflavone), respectively, by an extracellular crude enzyme solution from Phanerochaete chrysosporium. In the case of apigenin (1), two apigenin monomethyl ethers (2) and (3) and apigenin dimethyl ether (4) were formed by the conversion in yields of 3.9%, 2.4%, and 0.6%, respectively, of the starting compound. Enzymatic conversion of amentoflavone (13) by the conversion afforded many of its methyl ethers in the reaction products upon thin-layer chromatography (TLC). The four methyl ethers (14)-(17) were isolated from the reaction products, and the yields of the four ethers were 2.8%, 1.6%, 2.1%, and 0.5%, respectively, of the starting compound. The compounds (14)-(17) coincided with the four bisflavone methyl ethers having biological activities that were isolated from the leaves of icho (Ginkgo biloba L.). From the results, it was found that the bisflavone methyl ethers having biological activities existed in the leaves of icho could be prepared from amentoflavone by the conversion method, although the yields were small.

    To promote the production of haze (Rhus spp.) wax by the cultivation of haze cultivars, the chemical composition and physical properties of haze wax from 13 cultivars grown in Ehime Prefecture were investigated. The results were as follows: 1) The content of haze wax from 13 cultivars was in the range of 7-30.5%. The average wax content in the cultivars was 20.0%. 2) Based on a chemical analysis of the wax, no differences in the acid, ester, and saponification values of the wax from the cultivars were recognized, but there was a remarkable difference in the iodine values among the cultivars. 3) There was no difference in chemical compositions of main fatty acids (palumitic, oleic, stearic, archidic, and Japan acids) constituting haze wax in each cultivar. However, the content of Japan acid, a mixture of eicosanedioic and docasanedioic acids which is responsible for the viscoductile propety of haze wax, varied in each cultivar. The average content of Japan acid in the wax from the 13 cultivars was 3.86%. Each cultivar could be divided into four groups by the contents of the acid. Haze wax having greater contents of Japan acid had a tendency to exhibit greater visco-ductility. 4) There was no remarkable relationships between cultivars and physical properties (melting points, viscosities, penetration temperatures, and visco-ductilities, and so on) of the wax. However, smaller visco-ductility of the wax was recognized when the wax had a particularly large iodine value as well as plural penetration temperatures. 5) The Oho haze cultivar in the 13 cultivars was found to be a superior haze cultivar for the production of haze wax because the cultivar had both a large wax content and fine physical properties including great visco-ductility.

    Mechanical treatment of either syringaldehyde (1) or acetosyringone (2) with CBM (ceramic ball mill) gave no reaction product, but the treatments with both a VBM (vibration ball mill), and a laboratory refiner produced 3, 5-dimethoxy-p-benzoquinone (3). As a model compound with β-O-4 linkage, α-(2-methoxyphenoxy)-β-hydroxypropiosyringone (4) was therefore synthesized and treated mechanically to find out the reaction products. Differently from the cases of syringaldehyde (1) and acetosyringone (2), the treatments of a larger molecule of compound (4) with CBM, VBM, and a laboratory refiner produced 3.5-dimethoxy-p-benzoquinone (3) and others. By the mechanical treatments of compound (4) in the aqueous media, Daikin-type of radical splitting reactions of Car-Cα and Cα-Cβ bonds occurred to give firstly compounds (3), (10), and (11), secondly compounds (12) and (13). © 1992, The Society of Fiber Science and Technology, Japan.

    Treatment of both formaldehyde and creosol dispersed in linter pulp by either CBM and VBM furnished three condensation products I ˜ III. Addition of creosol to pine chips, “rough pulps” (Asplund pulps), and the mill-made “1R-pulps” (TMP), followed by the treatment with laboratory refiner also afforded products I ˜ III. Effect of pH of 4.0, 7.0, and 10.0 on the yields of condensation products I ˜ III was also examined for “rough pulps” and “1R-pulps” by refiner treatment. The higher the pH value, the yields of reaction products I and II increased. © 1992, The Society of Fiber Science and Technology, Japan. All rights reserved.
