Objective:
To study the chemical constituents of Botrychium lanuginosum.
Method:
Various chromatographic techniques were used to isolate and purify the constituents. The structures were elucidated by chemical evidence and spectroscopic methods.
Result:
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).
Conclusion:
Compounds 1-10 were isolated from this genus for the first time.
