[Studies on the chemical constituents from herba anoectochili].
OBJECTIVE
To study the chemical constituents in the whole herb of Anoectochiluts roxburghii (Wall) Lindl.


METHODS
The chemical constituents were isolated by various column chromatographic methods and structurally elucidated by IR, NMR and MS evidences.


RESULTS
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).


CONCLUSIONS
Compounds 6,7,9 and 11 from genera Anoeetochilus were isolated for the first time.
