Camellia reticulata Lindl.is valuable for its abundant nutrition and trace element from seed oil.For the edibility evaluation,it was determined and compared on physicochemical properties and main constituents of the oil originated from three regions.Results showed that the oil content of the seed was nearly 50%.For those originated from Zhenyuan of Yunnan Province and Yanbian of Sichuan Province,the iodine values of oil were 185.0 and 176.7,saponification values were 79.85 and 72.09,and refractive index was about 1.472 7.It was detected 5 fatty acids in the oil,among which the total unsaturated acids(9,12-octadecadienoic acid,9-octadecenoic acid and 11-eicosenoic acid) accounted over 80% of the total fatty acids,in concordance with the trends of edible oils.Moreover,there were plenty of mineral elements in the oil;especially the content of Fe was more than 3 times of that in the species originated from Tengchong,Yunnan.The seed oil of C.reticulata was potentially edible for special function and health care.
