Chemical composition and antioxidant capacity of extracts from the whole berry, pulp and seed of Hippophae¨ rhamnoides ssp. yunnanensis .

In the present study, profiles of fatty acid, sn-2 fatty acid, triglyceride, phytochemical (including tocopherol/tocotrienol, phytosterol, flavonoid, carotenoid and polyphenol) and antioxidant capacity of extracts from the whole berry, pulp and seed of Hippophae¨ rhamnoides ssp. yunnanensis were investigated and compared. The distributions of fatty acid, sn-2 fatty acid and triglyceride that was identified using ultra-performance liquid chromatography tandem quadrupole time of flight mass spectrometry (UPLC-Q-TOF/MS) showed obvious differences among the different parts of the ssp. yunnanensis . The whole berry and pulp extracts exhibited high flavonoid, carotenoid and polyphenol contents, whereas, the seed portion expressed high tocopherol/tocotrienol and phytosterol concentrations. Results deduced from this study demonstrated that ssp. yunnanensis is a rich source of unsaturated fatty acid and bioactive minor component, which should be further developed and utilized by breeders and planters.
