Abstract: 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.

Key words: non-food biodiesel plants, physicochemical property, evaluation, screening, Xiangxi region
