Abstract:
OBJECTIVETo study the chemical constituents of the whole plant Caragana spinifera.
METHODThe chemical constituents were isolated and repeatedly purified on silica gel column. The structures were elucidated by the NMR spectra and physico-chemical properties.
RESULTSix compounds were isolated and identified as (6aR, 11aR) 4,9-dimethoxy-3-hydroxypterocarpan, (6aR,11aR)-4, 9-dihydroxy-3- methoxypterocarpan (melilotocarpane B), 5, 4'-dihydroxy-7-methoxyisoflavone, 7-hydroxy4'-methoxyisoflavone, 6, 7-dihydroxy4'-methoxyisoflavone, beta-sitosterol respectively.
CONCLUSIONAll compounds were isolated from the plant for the first time.
