To study the chemical constituents of Oxytropis microphylla.
The compounds were isolated and purified by various column chromatographic techniques and their structures were elucidated on the basis of spectral analysis (EI-MS, 1H-NMR, 13C-NMR).
Eight compounds were isolated and identified as kaempferol (1), baicalein (2), 5-hydroxy-7, 8, 4'-trimethoxyflavone (3), stigmasterol (4), stigmast-4-en-3beta-ol (5), beta-sitosterol (6), lupenol (7), dehydrocostus lactone (8).
All compounds were isolated for the first time from this plant, compounds 2, 3, 5, and 8 were isolated for the first time from this genus.
研究小叶棘豆的化学成分。
采用多种柱色谱技术对化合物进行分离纯化，并通过光谱分析（EI-MS、1H-NMR、13C-NMR）确定其结构。
分离得到8个化合物，分别鉴定为山柰酚（1）、黄芩素（2）、5-羟基-7,8,4'-三甲氧基黄酮（3）、豆甾醇（4）、豆甾-4-烯-3β-醇（5）、β-谷甾醇（6）、羽扇豆醇（7）、去氢木香内酯（8）。
所有化合物均首次从该植物中分离得到，化合物2、3、5和8为首次从该属植物中分离得到。
