Correlation between phylogeny, chemical constituents and pharmaceutical aspects of plants and applications in drug research

Correlation between phylogeny, chemical constituents and pharmaceutical aspects of plants and applications in drug research. Part I. (Chinese Academy of Medical Sciences; Lab. Med. Plants, Inst. Mater. Med., Peking, Peop. R. China). Chih Wu Hsueh Pao, 19(3), 172-81 (Chinese) 1977. CODEN: CHWHAY. DOCUMENT TYPE: Journal CA Section: 63 (Pharmaceuticals) Section cross-reference(s): 11, 25, 26, 28 The pharmacol. properties and chem. constituents of 9 Artemisia, 14 Salvia, 8 Schizandra, 9 Dioscorea, 9 Paeonia and 6 Pueraria species were investigated and their clin. application explored. E.g., Salvia contg. tanshinones and cryptotanshinone [35825-57-1] are antimicrobial, Schizandra contg. wuweizisu C [61301-33-5], g-schizandrin [61281-37-6], wuweizichun B [61281-39-8], schizandrin [552-66-9] and deoxyschizandrin [61281-38-7] show blood serum transaminase-lowering activity, and Pueraria contg. daidzein [486-66-8], daidzin [552-66-9], and puerarin [3681-99-0] are capable of stimulating blood circulation.

HPLC determination of isoflavones in Ge Gen (Radix Puerariae) and its tablets

HPLC determination of isoflavones in Ge Gen (Radix Puerariae) and its tablets. Zhang, Yuzhong; Yang, Fan (Inst. Chin. Mater. Med., Acad. Tradit. Chin. Med., Peop. Rep. China). Yaowu Fenxi Zazhi, 4(2), 67-70 (Chinese) 1984. CODEN: YFZADL. ISSN: 0254-1793. DOCUMENT TYPE: Journal CA Section: 64 (Pharmaceutical Analysis) Daidzein 4',7-diglucoside [53681-67-7], puerarin [3681-99-0], 4'-methoxypuerarin [92117-94-7], daidzin [552-66-9] and daidzein [486-66-8] in Ge Gen (Puerariae roots) or their tablets were detd. by HPLC (Zorbax ODS as stationary phase; MeOH-H2O () as mobile phase). As an example, 0.1 g powder was extd. with 70% EtOH (10 mL), and 1 mL of the ext. was dild. with MeOH with addn. of internal std. A 0.6-mL soln. was subjected to anal. by HPLC. The retention time was 7.94, 12.97, 14.29, 20.09 and 53.76 min, resp. Contents of various isoflavones in roots of P. lobata from various locations in China ranged 0.0155-2.002, 0.108-5.749, 0.2411-1.908, 0.0175-1.393 and 0.049-0.155%, resp. No pretreatment of crude samples was required. The method was simple and rapid and only a small amt. of samples was required in anal.
