Abstract
Objective:
To study the chemical constituents of Gymnotheca involucrata.
Method:
Separating the constituents by means of chromatography and identifying their structures on the basis of NMR spectra and TLC with authentic samples.
Result:
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.
Conclusion:
All the three compounds were isolated from this genus for the first time.
