雪岭云杉针叶叶绿素-胡萝卜素软膏酸性物质化学组成的研究

STUDY ON THE CHEMICAL CONSTITUENTS OF ACIDIC FRACTION IN CHLOROPHYLL CAROTENE PASTE FROM NEEDLES AND TWIGS OF PICEA SCHRENKIANA

雪岭云杉针叶叶绿素胡萝卜素软膏中含酸性物质约２２ ％ （ 占软膏重） ，其中脂肪酸占４４－８６ ％ ，树脂酸占５２－４９ ％ 。该酸性物质经气相色谱和质谱定性、定量分析，共分离出３１ 个峰，鉴定出２６ 个化合物，被鉴定的组分占酸性物质总量的９７－３５ ％ 。其中主要成分为枞酸（２１－５５ ％ ） 、异海松酸（１２－８９ ％ ） 、油酸（１２－０７ ％ ） 、亚麻酸（７－３１ ％ ） 、新枞酸（６－１０ ％ ） 等。研究发现，雪岭云杉针叶叶绿素胡萝卜素软膏酸性物质中，不含松叶酸成分。

The acidic fraction of chlorophyll carotene paste from schrenk spruce ( Picea schrenkiana Fisch. et Mey. )needles and twigs was about 22 % of the paste,which consists of 44.86 % fatty acids and 52.49 % resin acids. The chemical constituents of the acidic fraction were analysed quantitatively and qualitatively by GC and GC MS,respectively. Of the 31 peaks,26 components which make up 97.35 % of the total acid were identified. The major components are abietic acid (21.55 %), isopimaric acid (12.89 %), oleic acid (12.07%), linolenic acid (7.31 %), neoabietic acid (6.10 %), etc. The research shows that no pinifolic acid have been found in the acidic fraction of chlorophyll carotene paste from needles and twigs of P. schrenkiana.
