[Studies on chemical constituents of herbs of Oxytropis microphylla]. Zhongguo Zhong yao za zhi = Zhongguo zhongyao zazhi = China journal of Chinese materia medica, 2009, Volume: 34, Issue:8 To study the chemical constituents of Oxytropis microphylla.. The compounds were isolated and purified by various column chromatographic techniques and their structures were elucidated on the basis of spectral analysis (EI-MS, 1H-NMR, 13C-NMR).. Eight compounds were isolated and identified as kaempferol (1), baicalein (2), 5-hydroxy-7, 8, 4'-trimethoxyflavone (3), stigmasterol (4), stigmast-4-en-3beta-ol (5), beta-sitosterol (6), lupenol (7), dehydrocostus lactone (8).. All compounds were isolated for the first time from this plant, compounds 2, 3, 5, and 8 were isolated for the first time from this genus. Topics: Chromatography, High Pressure Liquid; Flavanones; Flavonoids; Kaempferols; Lactones; Oxytropis; Sesquiterpenes; Sitosterols; Spectrometry, Mass, Electrospray Ionization; Stigmasterol; Triterpenes	2009
[Studies on ethyl acetate soluble constituents of Huanglian Jiedutang]. Zhongguo Zhong yao za zhi = Zhongguo zhongyao zazhi = China journal of Chinese materia medica, 2008, Volume: 33, Issue:18 To study the ethyl acetate soluble constituents from the water extractive of Huanglian Jiedutang decoction, which are composed of Rhizoma Coptidis, Radix Scutellariae, Cortex Phellodendri and Fructus Gardeniae, and provide substances foundation for its pharmacokinetic and pharmacodynamic investigation.. The chemical constituents were isolated by various column chromatographic methods and structurally elucidated by NMR and MS techniques.. Thirty-five compounds were isolated, among which twenty compounds have been identified as beta-sitosterol (1), oroxylin A (2), wogonin (3), ursolic acid (4), skullcapflavone I (5), tenaxin I (6), skullcapflavone II (7), limonin (8), 5, 2'-dihydroxy-6, 7, 8, 3'-tetramethoxyflavone (9), chrysin (12), baicalein (17), tenaxin II (19), 5, 7, 2'-trihydroxy-6, 8-dimethoxyflavone (21), shihulimonin A (22), 6, 2'-dihydroxy-5, 7, 8, 6'-tetramethoxyflavone (26), viscidulin II (28), 5, 7, 4'-trihydroxy-8-methoxyflavone (29), 5, 7, 2', 6'-tetrahydroxyflavone (30), wogonin-7-O-beta-D-glucuronide methyl ester (31) and daucosterol (34).. On the basis of reported results of the chemical constituents of Rhizoma Coptidis, Radix Scutellariae, Cortex Phellodendri and Fructus Gardeniae, it was estimated that all flavonoid compounds rised from the Radix Scutellariae, and compounds 8 and 22 rised from Cortex Phellodendri. Compound 22 was identified in the Cortex Phellodendri for the first time.
