[Chemical constituents of Oxytropis chiliophylla].
OBJECTIVE
To study the chemical constituents of Oxytropis chiliophylla.


METHODS
The air-dried whole plants of O. chiliophylla were extracted with EtOH (90%) three times at room temperature. The compounds were isolated by silica-gel, polyamide, C-18 and Sphadex LH -20 columns. The structures were identified based on spectral analysis.


RESULTS
8 compounds were isolated from O. chiliophylla and identified as azukisapogenol (1), (22E, 24R) -24-methyl-5alpha-cholesta-7, 22-diene-3beta, 5alpha, 6beta-triol (2), apigein (3), 3', 4'-dimethoxy-quercetin-3-O-beta-D-galactopyranoside (4), 7, 3', 4'-trimethoxy-quercetin-3-O-alpha-L-rhamopyranosyl-(1-->2)-beta-D-glucopyranoside (5), (2S, 3S, 4R)-N-[(R)-2'-hydroxytetracosanoyl]-1, 3, 4-trihydroxy-2-amino-octadeca-6-ene (6), beta-sitosterol (7), daucosterol (8).


CONCLUSIONS
All the compounds were isolated from O. chiliophylla for the first time.
