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.
