[Study on chemical constituents in herbs of Anoectochilus roxburghii II].
OBJECTIVE
To study the chemical constituents of Anoectochilus roxburghii.


METHODS
Silica gel and sephadex LH-20 column chromotography were used in the isolation from the ethanol extracts of the whole plant, the compounds were determined on the basis of various modern spectroscopic analysis and physical constants.


RESULTS
Five compounds were isolated from the CHCl3 soluble portion, identified as p-Hydroxybenzaldehyde (I), ferulic acid (II), quercetin (III), daucosterol (IV), cirsilineol (V).


CONCLUSIONS
All these compounds were isolated from the plant for the first time, compound V was isolated from the Orchid Family for the first time, the other compounds were isolated from this genus for the first time.
