Abstract

OBJECTIVE: To study the chemical constituents in the whole herb of Anoectochiluts roxburghii (Wall) Lindl. METHOD: The chemical constituents were isolated by various column chromatographic methods and structurally elucidated by IR, NMR and MS evidences. RESULT: Fourteen compounds were obtained and there into ten were identified as beta-sitosterol(2), ferulic acid(3), oleanolic acid(6), lanosterol(7), p-hydroxybenzaldehyde(8), 3-methoxyl-p-hydroxybenzaldehlde(9), daucosterol(10),3',4',7-trimethoxy-3, 5-dihydroxyflavone(11), isorhamnetin-3-O-beta-D-rutinoside(12) and rutin(13). CONCLUSION: Compounds 6,7,9 and 11 from genera Anoeetochilus were isolated for the first time.
