Components of volatile oil was analyzed with gas chromatography-mass spectrometry and the relative contents of compounds were calculated by peaks square of normalization. The results showed that yield of Passiflora edulis sims seed oil extracted by soxhelt method is higher than other methods. 22 components were observed and 19 of them were identified, which accounted for 95.91% of the total volatile oil extraction from Passiflora edulis sims seed by steam distillation. Main constituents in extraction were linoleic acid ethyl ester (25.64% ), 2,4-dimethy-Heptane (24.16% ), linoleic acid (14.17% ), ethyl palmitate (7.04% ). 18 components were separated and 17 components were identified, which accounted for 98.88% of the total volatile oil extraction from Passiflora edulis sims seed by soxhelt method. Main constituents were 2,4-dimethy-Heptane(35.13%), trans-cinnamaldehyde (16.71%), trans-anethole (12.52%), α-cubebene (11.45%). The results give basis for total exploration of Passiflora edulis sims seed. Key words: Passiflora
