Using electron spin resonance (ESR) we showed that PM suspensions as well as their particle-free, water-soluble fractions can generate ?OH in the presence of hydrogen peroxide (H2O2), an effect which was abrogated by both deferoxamine and catalase.

The ethyl ether-, acetone-, and water-soluble fractions obtained from the extract of oat shoots inhibited the germination and growth of roots and hypocotyls of lettuce (Lactuca sativa L.).

Dried young herbs of Artemisia scoparia Waldst et Kit. is one of the four commer- cial varieties of Ing-chen-hao, a drug used in Chinese Medicine for the treatment of jaundice. Chlorogenic acid, a choleretic principle, has been isolated from the water soluble fraction of its extract, which upon alkaline hydrolysis produced caffeic acid in yields around 0.4% of the crude drug.

Dried young herbs of Artemisia scoparia Waldst et Kit. is one of the four commer- cial varieties of Ing-chen-hao, a drug used in Chinese Medicine for the treatment of jaundice. Chlorogenic acid, a choleretic principle, has been isolated from the water soluble fraction of its extract, which upon alkaline hydrolysis produced caffeic acid in yields around 0.4% of the crude drug. Besides, choline was identified and isolated from this fraction. Caffeic acid also possesses choleretic activity. It has also been obtained from other varieties of the drug including A. capillaris Thunb. However, yields varied widely from a bare trace to 0.85%. Although 6,7-dimethoxycoumarin occurred in flower buds in 0.5%, yet it was absent from the young herbs of Artemisia scoparia.

濱蒿(Artemisia scoparia Waldst et Kit.)為四種商品茵陳蒿中之一種,從其提取物的水溶部分分離得到具有利膽作用的成分綠原酸.它的加堿水解產(chǎn)物咖啡酸也具有利膽作用,含量約占生藥的0.4％.此外,并分離確證有膽堿存在.從其他幾種商品茵陳蒿(包括A.capillaris Thunb.在內(nèi))也能得到咖啡酸,但得量高低懸殊,從微量到0.85％.雖然濱蒿花蕾中也含6,7-二甲氧基香豆素0.5％,但從其幼苗中卻未檢出此成分.

From the water soluble fraction of Angelica sinensis (oliv.) Diels (dang～gui), five constituents were isolated by chromatography and identified as ferulic acid, succinic acid, nicotinic acid, uracil and adenine. From the petroleum ether extract of Dang-gui, two compounds were isolated by preparative gas chromatography and identified as butylidenephthalide and ligustilide.All these constituents were found to be present in the injection solutions prepared from dang-gui.Feluric acid, succinic acid, nicotinic...

With leaf disks drilled from well grown tobacco (Nicotiana tabacum) plant are incubated in vitro, it is found that the extension of disks is inhibited in MS basal medium containing 2 ppm 6BA and free hydroxyproline. There is significant inverse correlation between disk extension and hydroxyproline concentration from 0.05 to 0.8 mM. When disks incubated for 3 days are provided with ~(14)C-proline, the radioactivity incorporated into disks and proteins is lower in the culture with MS basal medium or with MS basal...

With leaf disks drilled from well grown tobacco (Nicotiana tabacum) plant are incubated in vitro, it is found that the extension of disks is inhibited in MS basal medium containing 2 ppm 6BA and free hydroxyproline. There is significant inverse correlation between disk extension and hydroxyproline concentration from 0.05 to 0.8 mM. When disks incubated for 3 days are provided with ~(14)C-proline, the radioactivity incorporated into disks and proteins is lower in the culture with MS basal medium or with MS basal medium containing 2 ppm 6 BA and 0.3 mM hydroxyproline, in both of which the disks grow slowly, than in the culture with MS basal medium containing only 2 ppm 6 BA, in which the disks grow rapidly. However, the ratio of hydroxyproline/proline of slowly growing disks is higher than that of rapidly growing disks in both water-soluble fraction of cytoplasm and cell wall fraction. This means that the formation of hydroxyproline-rich proteins in large quantities is probably unfavourable to cell extension.

從生長(zhǎng)良好的煙草葉鉆下圓片進(jìn)行離體培養(yǎng)。發(fā)現(xiàn)在含有2 ppm 6BA的MS培養(yǎng)液中加入游離的羥脯氨酸,能明顯地抑制煙草葉圓片的擴(kuò)大生長(zhǎng).羥脯氨酸濃度在0.05 mM到0.8 mM范圍內(nèi)與圓片的擴(kuò)大生長(zhǎng)呈顯著負(fù)相關(guān)。用~(14)C-脯氨酸餵飼培養(yǎng)了3天的煙草葉圓片,發(fā)現(xiàn)在無(wú)激素的MS培養(yǎng)液中和在含有2 ppm 6BA+0.3 mM羥脯氨酸的MS培養(yǎng)液中生長(zhǎng)緩慢的圓片,其放射性摻入圓片和摻入蛋白質(zhì)的量均低于在含2 ppm 6BA的MS培養(yǎng)液中迅速生長(zhǎng)的圓片。然而,生長(zhǎng)緩慢的圓片,其細(xì)胞質(zhì)水溶性部分和細(xì)胞壁部分羥脯氨酸/脯氨酸之比值卻都高于迅速生長(zhǎng)的圓片。這意味著富含羥脯氨酸蛋白質(zhì)的大量形成可能不利于細(xì)胞的擴(kuò)大生長(zhǎng)。細(xì)胞壁中放射性的摻入量隨餵飼時(shí)間的延長(zhǎng)而增加,羥脯氨酸/脯氨酸比值也隨餵飼時(shí)間的延長(zhǎng)而提高,這說(shuō)明在細(xì)胞壁中亦可能有脯氨酸的羥基化過(guò)程發(fā)生。
