to study the chemical components of the leaves from Crataegus pinnatifida Bge. var major N. E. Br.
Constituents were isolated by using silica gel, porous resin, Sephadex LH-20 chromatographic technique, etc. Their structures were elucidated by chemical and spectroscopic methods.
Fourteen compounds were identified as quercetin (1), hyperoside (2), quercetin 3-O-beta-D-glucoside (3), rutin (4), quercetin 3-O-[alpha-L-rhamnopyranosyl(1-4)-alpha-L-rhamnopyranosyl-(1-6)-beta-glucopyranoside] (5), vitexin (6), 6"-O-acetyl-vitexin (7), vitexin 2"-O-rhamnoside (8), vitexin 4"-O-glucoside (9), chlorogenic acid (10), ursolic acid (11), beta-sitosterol (12), beta-daucosterol (13), n-triacontanol (14).
Compound 5 and 14 were isolated from Crataegus L. for the first time.
研究山里红叶片的化学成分。
采用硅胶、大孔树脂、葡聚糖凝胶LH - 20等色谱技术进行成分分离,通过化学和光谱方法鉴定其结构。
鉴定出14种化合物,分别为槲皮素(1)、金丝桃苷(2)、槲皮素3 - O - β - D -葡萄糖苷(3)、芦丁(4)、槲皮素3 - O - [α - L -鼠李糖基(1→4)-α - L -鼠李糖基 -(1→6)-β -葡萄糖苷](5)、牡荆素(6)、6″ - O -乙酰基牡荆素(7)、牡荆素2″ - O -鼠李糖苷(8)、牡荆素4″ - O -葡萄糖苷(9)、绿原酸(10)、熊果酸(11)、β -谷甾醇(12)、β -胡萝卜苷(13)、正三十烷醇(14)。
化合物5和14首次从山楂属植物中分离得到。
