Abstract

This study investigated the chemical and volatile characteristics of sea buckthorn fruits from three different regions in China. The chemical composition of the volatile oil was determined by using a non-targeted gas chromatography and mass spectrometry (GC/MS) method and the differences in chemical composition among the three producing areas were compared by heatmap providing a visual basis for researchers. A total of 93 compounds were identified, including 52 compounds from the Northeast China, 51 from the Xinjiang region, and 37 from Inner Mongolia region. Then, the in vitro antioxidant activity of sea buckthorn fruit oil was measured using DPPH, ABTS, and SOD inhibition tests, and the results showed that sea buckthorn fruit oil in northeast China was the strongest antioxidant, followed by Inner Mongolia and Xinjiang. The results of the CCK-8 experiment indicated that within the tested concentration, there is no cell cytotoxicity of the essential oil in human umbilical vein endothelial cells (HUVECs) cells. The results could supply reference to distinguish sea buckthorn fruit from different production areas and, meanwhile, clarify the activity and safety of sea buckthorn oil.

Keywords: Antioxidant Activity; Fingerprints; Heat map; Sea buckthorn; Sea buckthorn fruit oil.
