摘要
目的:研究齿叶地不容Stephania dentifolia的化学成分。方法:应用氧化铝、硅胶和葡聚糖凝胶LH-20等柱色谱方法分离化合物,根据理化性质测试和波谱分析鉴定化合物结构。结果:从齿叶地不容新鲜块茎的稀硫酸提取物中,分离得到8个生物碱成分,分别为青风藤碱(sinoacutine,1)、青藤碱(sinomenine,2)、8-甲氧基青藤碱(cephamonine,3)、四氢巴马汀(tetrahydropalmatine,4)、卡巴任(capaurine,5)、千金藤宁碱(stepharanine,6)、(+)-stepharine(7)、巴马汀(palmatine,8)。结论:所有化合物均为首次从齿叶地不容中分离得到。
Eight alkaloids were isolated from the thin sulfuric acid extracts of the fresh roots of Stephania dentifolia by aluminum oxide, silica and Sephadex LH-20 column chromatography methods. Based on the spectroscopic analysis and chemical evidence, the structures of these alkaloids were identified as sinoacutine ( 1 ) , sinomenine (2) , cephamonine (3) , tetrahydropalmatine (4) , capaurine (5), stepharanine (6), ( + )-stepharine (7) and palmatine (8). All compounds were obtained from this plant for the first time.
