枇杷叶在日本民间供药用。本文对挥发油的成分进行了研究。将枇杷(Eriobotrya japonica)的新鲜叶的水蒸馏液以乙醚提取,经硫酸钠干燥后,蒸去乙醚得挥发油,收率为0.045～0.108%。气相层析表明,约有29种组分,主要成分为橙花叔醇(Nerolidol)60.6～73.8%及金合欢醇(Famesol)6.8～15.6%。奈良地区的枇杷叶中的挥发油和橙花叔醇的含 Loquat leaves for private use in Japan. In this paper, the composition of volatile oil has been studied. The aqueous extract of fresh leaves of Eriobotrya japonica was extracted with diethyl ether and dried over sodium sulfate. Evaporation of the ether afforded the essential oil in a yield of 0.045-0.108%. Gas chromatography showed that there were about 29 components with the main components of 60.6-73.8% of Nerolidol and 6.8-15.6% of Famesol.
