Studies on chemical constituents from herbs of Botrychium lanuginosum / 中国中药杂志

ABSTRACT

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