Determination of Biomedical Constituents of 350 °C Pyrolyzate from Benzene/ethanol Extractives of Old Bark from Cinnamomum camphora Trunk

摘要

The extractives of C camphora old bark were used to cure some special diseases; however,the biomedical constituents of extractives of C.camphora old bark are still not completely explained.Therefore,350 °C-based pyrolysis-GCMS technology was used to identify the top value-added biomedical constituents of old bark-based benzene/ethanol extractives from C.camphora trunk.74 chemical constituents representing 99.17％ were identified from 86 peaks.The main components are as:Dodecanoic acid,l-(hydroxymethyl)-l,2-ethanediyl ester (15.717％),Octacosanoic acid,methyl ester (10.357％),Abietic acid (8.483％),Heptacosane (5.678％),Ethyl alcohol (5.282％),Hexadecanoic acid,2-hydroxy-,methyl ester (3.365％),Hexacosanoic acid,methyl ester (2.936％),1,2-Benzenedicarboxylic acid,butyl 2-methylpropyl ester (2.928％),2-Methoxy-4-vinylphenol (2.692％),Hexadecanoic acid,ethyl ester (2.312％),Hexacosane (2.076％),Tetracosanoic acid,methyl ester (2.013％),etc.The analytical result showed that the 350 °C pyrolyzate of benzene/ethanol extractives from C.camphora old bark is abundant in biomedical constituents,and also contains other bioactive components,which can be used as top value-added materials of high-grade cosmetic,food,spice and chemical solvents.
