滇产樟属植物精油的化学研究

The Chemical Studies of Cinnamomum Trew Plants from Yunnan Province

本文研究了云南樟属（Ｃｉｎｎａｍｏｍｕｍ Ｔｒｅｗ）５种植物１４个样品，测定了得油率．其得油率（质量分数Ｗ）叶子为０．３１％～１．７２％，树皮为０．５１％～２．０５％；从挥发油中鉴定了约７０种化学成分，主要含有桂皮醛、水杨醛、苯甲醛、肉桂酸、乙酸肉桂酯等．

samples of Cinnamomum Trew plants from Yunnan Province were studied. The essential oil yield and their chemical constituents were determined. The essential oil yield are about 0. 31 %-1. 72% (leaf) and 0. 51 % -2. 05 % (bark). 70 kinds of chemise constituents were identified from essential oil, which are cinnamic aldehyde, benzaldehyde, cinnamyl acetate, cinnamylic acid and so on.
