连翘子系植物连翘Forsythia suspensa的干燥种子,药名连翘心,中医用于邪陷心包、神昏谵语诸证。作者首次从连翘子中分离鉴定β-Amyrin-3-acetate。取连翘心1118克粉碎,经石油醚提得亮黄色脂肪油(431.4克)静置数月,倾出脂肪油,收集固体并加少量石油醚除去固体表面残留脂肪,石油醚重结晶至熔点234～235℃,呈无色针状结晶。再以丙酮重结晶,得无色细长板针状结晶1.40克,熔点240～241℃,[α](?)=+77.4°(C=0.9,
Forsythia suspensa, the dry seed of the Forsythia Suspension plant, the drug name Forsythia sinensis, the Chinese medicine used in evil trap pericardium, Shenmao proverbs. The authors isolated and identified β-Amyrin-3-acetate from Forsythia suspensa for the first time. Take 1118g of Forsythia crushed, and obtain a bright yellow fatty oil (431.4g) by petroleum ether. Let stand for several months. Pour off the fatty oil. Collect the solid and add a small amount of petroleum ether to remove residual fat from the solid surface. Re-crystallize the petroleum ether to the melting point. 234 ~ 235 °C, was colorless needle crystal. Recrystallization from acetone gave 1.40 g of a colorless, elongated, needle-like crystal, melting point 240-241°C, [α](?)=+77.4° (C=0.9,
