[Studies on chemical constituents of Caragana spinifera].
OBJECTIVE
To study the chemical constituents of the whole plant Caragana spinifera.


METHODS
The chemical constituents were isolated and repeatedly purified on silica gel column. The structures were elucidated by the NMR spectra and physico-chemical properties.


RESULTS
Six 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.


CONCLUSIONS
All compounds were isolated from the plant for the first time.
