To study the chemical constituents of Pseudostellaria heterophylla.
The compounds were isolated by silica gel and Sephadex LH-20 column chromatography and purified by recrystallization. Their structures were elucidated on the basis of physicochemical properties and spectral analysis.
Seven compounds were identified as 2-minalin (1) , 3-furfuryl pyrrole-2-carboxylate (2), ursolic acid (3), acacetin (4), luteolin (5), acacetin 7-O-beta-D-glucopyranosyl (6-->1)-alpha-L-rhamnopyranoside (6).
Among them, compounds 3-6 were isolated from the plant for the first time.
研究太子参的化学成分。
采用硅胶柱色谱和葡聚糖凝胶LH - 20柱色谱分离化合物,通过重结晶进行纯化。根据理化性质和光谱分析确定其结构。
鉴定出7个化合物,分别为2 - 米纳林(1)、3 - 糠基吡咯 - 2 - 羧酸酯(2)、熊果酸(3)、刺槐素(4)、木犀草素(5)、刺槐素7 - O - β - D - 吡喃葡萄糖基(6→1)- α - L - 鼠李吡喃糖苷(6)。
其中,化合物3 - 6首次从该植物中分离得到。
