Abstract:
OBJECTIVETo study the chemical constituents of Gueldenstaedtia stenophylla.
METHODVarious chromatographic techniques were used to separate and purify the constituents and structure determination was mainly based on the analysis of the spectroscopic data.
RESULTSeven 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.
CONCLUSIONAll these compounds were isolated from the genus Gueldenstaedtia for the first time.
