| Abstract: |
| The basic physicochemical indexes, fatty acid composition, glyceride composition, triglyceride composition and trace components of the seed oils of Trichosanthes kirilowii (TKO) from Anhui, Henan and Shandong were comparatively analyzed. The results showed that the TKO from the three regions showed a dark green color. Triglycerides was main components in TKO.TKO was rich in oleic acid (1713%-26.17%), linoleic acid (35.83%-37.91%) and trichosanic acid (22.57%-3747%), and the content of unsaturated fatty acids reached above 93%. The content of trichosanic acid in TKO from Henan was the highest (37.47%). The fatty acids at sn-2 position were mainly linoleic acid and oleic acid, and trichosanic acid was mainly distributed at sn-1,3 position. The principal components of triglyceride in TKO from three regions were β-TcLO, β-TcLL and β-TcLTc. The total content of tocopherols in TKO from three regions was 415.71-486.59 mg/kg, in which the content of γ-tocopherol (67%-74%) was the highest, followed by α-tocopherol (25%-33%). Five kinds of sterols were detected from TKO, and the total content of sterols was 0.19%-0.28%. |
