| Abstract: |
| In order to discover new components in sesame oil, the methanol extracts of four kinds of sesame oils were detected and analyzed by UPLC/Q-TOF MS/MS. The results showed that 143 common components in sesame oil were found, including 71 in the positive ion mode and 72 in the negative ion mode. A total of 77 components among 143 were identified, and the remaining 66 components were unidentified. The 77 identified components included 12 known components such as sesamin, sesamolin, eight fatty acids and derivatives and stearamide, and 65 newly discovered components. The newly discovered components included 17 fatty amides (erucamide, 8-methyl-N-vanillyl-nonamide, oleamide, palmitamide, linoleamide, capsiamide, N-stearoyl alanine, etc), 22 fatty acids and derivatives (hexadecenoic acid, octadeceneic acid, etc), 5 flavonoids such as 5-deoxyvitanol and tinosporinone, 21 other ingredients such as matairesinol, ginkgoic acid,etc. The sesame oil contains a large number of new and unknown components, and rich in fatty acids, fatty acid amides, flavonoids, lignans and other substances, which can explain its unique physiological functions. |
