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。
