5种能源植物种子含油量与脂肪酸组成 . Oil contents and relative components of fatty acid in the seeds of five energy plants

Abstract

Energy plants are the important bioenergy raw materials. In order to find the potential energy plants, we measured the seed oil contents of Jatropha curcas, Datura stramonium, Xanthium sibiricum, Rhus typhina, Kosteletzkya pentacarpos and Hibiscus trionum by using Soxhlet Extraction Method, and analyzed the relative components of the fatty acid composition by using GC-MS Method. The results showed that except for R. typhina which seed oil content is 9.50%, the other five plants has more than 17% of seed oil contents. The unsaturated fatty acid contents of the five plants except for R. typhina range from 73.51% to 92.23%, and the unsaturated C18 ranges from 67.9% to 92.23%, which is the main component of biodiesel. Our data showed that J. curcas, D. stramonium, X. sibiricum, K. pentacarpos and H. trionum grown in marginal land are potential energy plants, which can be used for the development and utilization of biomass energy.
