To study the flavonoids in the leaves of Apocynum ventum.
Compounds were separated by repeated polyacrylamide column chromatgraphy combined with Sephadex LH-20 column chromatgraphy, their structures were confirmed by the analysis of spectral data and physicochemical properties.
Six compounds were isolated from A. ventum. They were elucidated as quercetin (1), kaempferol (2), kaempferol-3-O-(6"-O-acetyl)-beta-D-glucopyranoside (3), quercetin-3-O-(6"-O-acetyl )-beta-D-glucopyranoside (4), quercetin-3-O-(6"-O-acetyl)-beta-D-galactopyranoside (5), kaempferol-7-O-alpha-L-rhamnopyranoside (6).
Compound 5 and 6 were isolated from the genus Apocynum for the first time.
研究罗布麻叶中的黄酮类化合物。
采用反复聚丙烯酰胺柱色谱结合葡聚糖凝胶LH - 20柱色谱分离化合物,通过光谱数据分析和理化性质确定其结构。
从罗布麻中分离得到6个化合物,分别鉴定为槲皮素(1)、山柰酚(2)、山柰酚 - 3 - O -(6″ - O - 乙酰基)- β - D - 吡喃葡萄糖苷(3)、槲皮素 - 3 - O -(6″ - O - 乙酰基)- β - D - 吡喃葡萄糖苷(4)、槲皮素 - 3 - O -(6″ - O - 乙酰基)- β - D - 吡喃半乳糖苷(5)、山柰酚 - 7 - O - α - L - 鼠李糖苷(6)。
化合物5和6为首次从罗布麻属植物中分离得到。
