Oil content and fatty acid composition in Toxicodendron vernicifluum kernels from different provenances
In order to find out the effects of provenances on the oil contents and the compositions of fatty acid in Toxicodendron vernicifluum kernels, and to provide some references for selection and breeding of new varieties of T. vernicifluum taking unsaturated fatty acids as the target, using the T. vernicifluum seeds from Dafang county of Guizhou, Fuyuan county and Nujiang Lisu Autonomous Prefecture of Yunan, and Langao county of Shaanxi as experiment materials, the oil contents and fatty acid compositions were determined by Soxhlet extraction and GC-MS. The results showed that the oil contents in kernels from four provenances were 17.4%, 22.1%, 13.3%, and 13.1%, and they had very significant differences between different provenances. Fatty acid compositions in seed oils had obvious differences between different provenances. For example, fatty acid kinds in seed oil from Dafang of Guizhou was the most (total 23 kinds), and that from Nujiang of Yunnan was the least (total 20 kinds). The contents of unsaturated fatty acids from different provenances had obvious differences, ranging from 65.76% to 81.10%, and the amplitude was 15.34%. There were more than 20 kinds of fatty acids in oils from four provenances, and the ratios of main fatty acid contents to total fatty acid contents were respectively 96.99%, 96.88%, 97.31%, and 98.07%.
