RESUMEN
OBJECTIVE: To study the chemical constituents of the ethnic drug Dicranopteris pedata. METHODS: The compounds were isolated and purified by comprehensive application of silica gel and Sephadex LH-20 chromatography, and their structures were identified on the basis of comprehensive analysis of their physical and chemical properties, NMR data and references. RESULTS: Fourteen compounds were isolated and elucidated as quercitrin(1), kaempferol 3-O-α-L-rhamnoside(2), rutin(3), hyperoside(4), kaempferol(5), quercetin(6),2-hydroxy-4-methoxy-2',3'-benzochalcone(7),stigmasterol(8), cycloastragenol(9), shikimic acid(10), protocatechuic acid(ll), gallic acid(12),β-sitosterol(13), and daucosterol(14). CONCLUSION: Compound 1-14 are for the first time isolated from D. pedata.
