[Studies on chemical constituents from herbs of Botrychium lanuginosum].

OBJECTIVE

To study the chemical constituents of Botrychium lanuginosum.

METHODS

Various chromatographic techniques were used to isolate and purify the constituents. The structures were elucidated by chemical evidence and spectroscopic methods.

RESULTS

Ten compounds were isolated from the 95% ethanol extract of the herb of B. lanuginosum and their structures were elucidated as 30-nor-21beta-hopan-22-one (1), beta-sitosterol (2), luteolin (3), thunberginol A (4), apigenin (5), (6'-O-palmitoyl)-sitosterol-3-O-beta-D-glucoside (6), daucosterol (7), 1-O-beta-D-glucopyranosyl-(2S, 3R, 4E, 8Z)-2-[(2R-hydroxy hexadecanoyl) amino]-4, 8-octadecadiene-1, 3-diol (8), luteolin-7-O-glucoside (9), sucrose (10).

CONCLUSIONS

Compounds 1-10 were isolated from this genus for the first time.
