[Chemical constituents of Gymnotheca involucrata Pei].Zhongguo Zhong Yao Za Zhi. 2001 Jan; 26(1):43-5.ZZ
To study the chemical constituents of Gymnotheca involucrata.
Separating the constituents by means of chromatography and identifying their structures on the basis of NMR spectra and TLC with authentic samples.
From the methanolic extract of the whole plant of G. involucrata, three compounds were isolated and identified as kaempferol-4',7-dimethyl-3-O-glucoside, daucosterol and stigmasterol.
All the three compounds were isolated from this genus for the first time.
