Abstract

The edible berries of three plants indigenous to the Tibetan plateau, namely Nitraria tangurorum B. (NTB), Hippophae rhamnoides L. (HRL) and Berberis dasystachya M. (BDM), have been used for medicinal purposes for a long time. For these three berries that occur in the wild, it is important to understand the differences between the content and biological activity of their seed oils. Therefore, this study was designed in order to determine the total polyphenol content (TPC), carotenoid content (TCC), steroid content (TSC) and fatty acid composition of seed oils obtained from these three berries, using standard analytical methods. In addition, in vivo anti-fatigue activity of three seed oils were investigated using forced swimming mice. Free radical scavenging activity and antioxidant capacity were estimated using different assays. The results indicated that seed oil of these three berries contained a variety of active compounds. BDM seed oil showed a higher TPC concentration of 281.61 ± 19.06 µg/g compared to the other berries; HRL seed oil showed a higher TSC concentration of 329.06 ± 16.53 µg/g compared to the other berries. The total content of polyunsaturated fatty acids in seed oils from the three berries was found to be 331.6, 342.91 and 305.39 µg/mL for NBT, HRL, and BDM, respectively. The antioxidant assay results indicated that the seed oil obtained from HRL was significantly more active in scavenging free radicals compared to the other seed oils. Therefore, the results indicate that such seed oil supplements could prevent lipid oxidation in forced swimming mice.
