Quantitative contents of some groups of phenolic compounds in components of an alder tree

Quantitative contents of some groups of phenolic compounds in components of an alder tree. Grechin, P. V.; Khvorost, O. P. 25429-38-3 and 7295-85-4 are also occured in this study.; Serbin, A. G. (Nats. Farm. Univ. Ukr., Kiev, Ukraine). Farmatsevtichnii Zhurnal (Kiev), (4), 82-84 (Ukrainian) 2003 Zdorov'ya. CODEN: FRZKAP. ISSN: 0367-3057. DOCUMENT TYPE: Journal CA Section: 11 (Plant Biochemistry) The sum of oxidized phenols (method of GPh XI), the sum of tanning agents (by the method of complexonometric in recalcn. on tanning agents of alder bark), the sum of hydroxycinnamic acids (spectrophotometric method in recalcn. on a chlorogenic acid), the sum of catechols (spectrophotometric method in recalcn. on (±)catechin) is detd. The bark of stems is richest in phenolic compds. (sum oxidized phenolic compds. comprises 20.57 ± 0.12, the sum of tanning agents 3.66 ± 0.08, the sum of hydroxycinnamic acids 0.43 ± 0.02, the sum of catechols 7.42 ± 0.02). Results of quant. detn. of these groups of phenolic compds. are to be used for the development of the AND project on a bark of an clammy alder. .

Active choleretic principle in Yemeigen (root of Prunus mume)

Active choleretic principle in Yemeigen (root of Prunus mume). Chen, Zhaonan; Sun, Shisheng; Xu, Qi; Liu, Guangyu; Hu, Shuying; Wu, Zhenlie (Wenzhou Inst. Pharm. Sci., Wenzhou, Peop. Rep. China). Zhongcaoyao, 17(11), 482-3 (Chinese) 1986. CODEN: CTYAD8. ISSN: 0253-2670. DOCUMENT TYPE: Journal CA Section: 1 (Pharmacology) (±)-Catechin [7295-85-4] and (-)-epicatechin [490-46-0] were isolated from Yemeigen (root of P. mume). 490-46-0 and 7295-85-4 which are cas registry numbers of substances are two of reagents here. In dogs and rats (±)-catechin, at 50 and 300 mg/kg, resp., had marked choleretic effect; (-)-epicatechin was ineffective at 50 mg/kg in dogs. .
