从刺五加Eleutherococus senticocus中提取到含活性成分cirindine的催眠药。cirindine外观为无色针晶,UV220nm和265nm,mp192℃,元素分析:C 54.83％,H6.5％,O 38.67％,可溶于水和甲醇。该药药性温和。用33％乙醇提取刺五加根得6.8L提取液,经浓缩后用乙醚提取,除去脂溶部分。水溶部分,浓缩再经离子交换柱得600ml洗脱液,经干燥得2.7g,行硅胶层析,取Rf值为 The hypnotic agent containing the active ingredient cirindine was extracted from Eleutherococus senticocus. The appearance of cirindine is colorless needles, UV220nm and 265nm, mp192°C. Elemental analysis: C 54.83%, H6.5%, O 38.67%, soluble in water and methanol. The medicine is mild. 33% ethanol was used to extract Acanthopanax Senticosus 6.8 L extract, concentrated and extracted with ether to remove the fat-soluble fraction. The water-soluble fraction was concentrated and then subjected to an ion-exchange column to obtain 600 ml of an eluent, which was dried to give 2.7 g. The silica gel was subjected to chromatography to obtain the Rf value.
