摘　　要：随着煤炭、石油等化石能源价格的不断上涨,加快可再生能源,尤其是生物质能源的发展,以推进能源替代,被认为是解决全球能源危机的最理想途径之一（唐红英,2008）。目前,世界各国,尤其是发达国家,都致力于开发高效、无污染的生物质能源利用技术,以保障能源安全,实现CO2减排,促进经济、社会的可持续发展（Holdren,1991）。Oil rate and fatty acids content were analyzed in Idesia palycarpa Maxim fruits,sampled from nine different geographical populations in the main I. palycarpa distribution areas in China and one cultivated in the process of fruitsripening,were analyzed in this paper. Oil rate of fruits were measured with a national standard method and fatty acids content of fruits was quantitatively determined by using a pre-column derivatization gas chromatograph （ GC） with the reference substarces. The results showed that fruits of Ningqiang population from Shaanxi Province had the highest oil rate （44. 08 ± 0. 5 % ） and was the most potential utilization value population. The best harvesting time for cultivated I. palycarpa fruits was November 15 every year and by then oil rate of fruit was the highest. There were six main fatty acids in I. palycarpa fruit oil,including to palmitic acid,methyl palmitelaidate,octadecanoic acid,oleic acid,linolenic acid, and linoleic acid,among which Linolenic acid was the dominant component.
