Objective:
To study the chemical constituents of Gueldenstaedtia stenophylla.
Method:
Various chromatographic techniques were used to separate and purify the constituents and structure determination was mainly based on the analysis of the spectroscopic data.
Result:
Seven compounds, including 2', 4, 7-trihydroxy-4'-methoxyisoflavans (1), genkwanin (2), quercetin (3), rutin(4), 12-oleanen-3beta, 22beta, 24-triol (5), betulinic acid (6), and 3, 4-dihydroxybenzoic acid (7) were isolated and identified.
Conclusion:
All these compounds were isolated from the genus Gueldenstaedtia for the first time.
