Studies on chemical constituents of Caragana spinifera / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study the chemical constituents of the whole plant Caragana spinifera.</p><p><b>METHOD</b>The chemical constituents were isolated and repeatedly purified on silica gel column. The structures were elucidated by the NMR spectra and physico-chemical properties.</p><p><b>RESULT</b>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.</p><p><b>CONCLUSION</b>All compounds were isolated from the plant for the first time.</p>
