To study the chemical constituents from the roots of Pterospermum heterophyllum.
The chemical constituents of P. heterophyllum were isolated and purified by silica gel and sephadex LH-20 column chromatography. Their structures were identified on the basis of spectroscopic data and physicochemical properties.
Nine compounds were isolated and identified as taraxerol (1), betulin (2), betulinic acid (3), sumaresinolic acid (4), 2-methoxy-5-hydroxy-1, 4-naphthoquinone (5), 5, 7-dihydroxy-6, 8-dimethylchromone (6), alpha-monpalmitin (7), palmitic acid (8), beta-sitosterol (9).
Compounds 2-7 were isolated from this genus for the first time.
研究异叶翅子树根部的化学成分。
采用硅胶柱色谱和葡聚糖凝胶LH - 20柱色谱对异叶翅子树的化学成分进行分离纯化，并根据光谱数据和理化性质鉴定其结构。
分离鉴定出9个化合物，分别为蒲公英赛醇（1）、白桦醇（2）、白桦酸（3）、苏门树脂酸（4）、2 - 甲氧基 - 5 - 羟基 - 1,4 - 萘醌（5）、5,7 - 二羟基 - 6,8 - 二甲基色酮（6）、α - 单棕榈酸甘油酯（7）、棕榈酸（8）、β - 谷甾醇（9）。
化合物2 - 7为首次从该属植物中分离得到。
