Total phenolic content, total antioxidant activity of Myrobalan plum (Prunus cerasifera Ehrh.) and anthocyanin content in peel were analyzed in this article. In addition, ultra-performance liquid chromatography with photodiode array detection and electrospray ionization tandem mass spectrometry were used to determine anthocyanin composition of this fruit. The range of total phenolic content of the tested samples was 1.34 to 6.11 g/kg fresh weight (FW), and anthocyanin content in fruit peel of Myrobalan plum was from 1.93 to 19.86 g/kg peel. Ferric reducing antioxidant power values varied from 11.20 to 44.83 μmol Trolox equivalent/g FW. Four main kinds of anthocyanins in purple Myrobalan plum were detected while 6 kinds in red ones.
The article showed the anthocyanin composition, phenolic content, and antioxidant activities of wild Myrobalan plum. The purple Myrobalan plum could be developed as a resource of fruit drinks because of its high antioxidant activity and the peel could be used as the resource to extract natural pigments.
本文分析了桃金娘李(Prunus cerasifera Ehrh.)的总酚含量、总抗氧化活性和果皮中的花色苷含量。此外,还使用超高效液相色谱-光电二极管阵列检测和电喷雾串联质谱法来确定这种水果的花色苷组成。测试样品的总酚含量范围为 1.34 至 6.11g/kg 鲜重(FW),桃金娘李果皮中的花色苷含量为 1.93 至 19.86g/kg 果皮。铁还原抗氧化能力值范围为 11.20 至 44.83μmol Trolox 当量/g FW。在紫色桃金娘李中检测到 4 种主要的花色苷,而在红色桃金娘李中检测到 6 种。
本文展示了野生桃金娘李的花色苷组成、酚含量和抗氧化活性。由于其高抗氧化活性,紫色桃金娘李可作为水果饮料的资源,其果皮可用作提取天然色素的资源。
