摘　　要：根据国家标准方法测定酸值、碘值、皂化值及脂肪酸组成,分析湘西地区88种含油量在30%以上的非粮油脂植物籽油的理化性质,并对其进行综合评价筛选。结果显示:所测定的88种植物中,酸值介于0.63~202.35 mg/g之间,碘值介于1.85%~288.26%之间,皂化介于70.72~576.16 mg/g之间,亚麻酸质量分数介于0.02%~63.93%之间。按照湘西地区非粮油脂植物的筛选指标,88种植物中共有11种符合标准。运用层次分析(AHP)法从物种的自然特性、种子油脂理化特性和油脂的能源成分3个方面共8个评价指标对这11个物种进行综合评价,综合得分排序为:山橿>算盘子>湖南山核桃>牛蒡>蜡梅>猴欢喜>华榛>猫儿屎>白檀>尖连蕊茶>复羽叶栾树。通过综合判断分析认为适合在湘西地区发展的5种非粮油脂植物物种为山橿、湖南山核桃、牛蒡、蜡梅和白檀,其中以山橿和湖南山核桃为优选、首选物种。The physical and chemical properties of seed oil from 88 non-food biodiesel plants species with the oil content 30% in Xiangxi region were analyzed,evaluated and screened by measurement of acid value,iodine value,saponification value and the components of fatty acids. The results showed that within the 88 species,the acid value,iodine value,saponification value and linolenic acid in the oil ranged from 0. 63-202. 35 mg/g,1. 85%-288. 26%,70. 72-576. 16 mg/g and 0. 02%-63. 93 %,respectively. According to the evaluation standard in Xiangxi region,14 species of 88 non-food biodiesel plants species were preliminarily screened. Based on the analytic hierarchy process（ AHP） from 8 evaluation indexes,belonging to three classes,i.e.,the specie natural property,seed oil physicochemical property and the oil composition content,these 11 non-grain biodiesel plants were evaluated and ranked as Lindera reflexa〉Glochidion puberum〉Carya hunanensis〉Arctium lappa〉Chimonanthus praecox〉Sloanea sinensis 〉Corylus chinensis〉 Decaisnea insignis 〉Symplocos paniculata Camellia cuspidata Koelreuteria bipinnata.Combing the biological traits of these species, it was proposed that L. reflexa,C. hunanensis,A. lappa,C. praecox and S. paniculata were suitable for the biodiesel development in Xiangxi region, among which four species（ L. reflexa and C. hunanensis） showed the largest potentiality.
