thunberginol-a and lyoniside

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