Abstract:The kernel of lodes vitiginea (Hance) Hemsl. (Icacinaceae) contains 39---50% of oil. Analysing with GC, the main fatty acids are hexadecenoic and palmitic acid. By means of ozonization, GC/MS, IR, etc., the hexadecenoic acid was identified as cis- 7-hexadecenoic acid. Thirteen triglycerides (peak) have been separated by HPLC from oil, among them, eight triglycerides were identified by C,C with HHH, 18.4; HHP, 32.3%; PHP, 16.8% as the main composition.
