Anthocyanins composition and antioxidant activity of two major wild Nitraria tangutorun Bobr. variations from Qinghai–Tibet Plateau

Nitraria tangutorun Bobr., a unique kind of fruit, widely spreads in the Qinghai–Tibet Plateau. In the present study, nine anthocyanins were identified in two variations (purple fruit and red fruit) of N. tangutorun by HPLC/DAD–ESI/MS.

Description
Summary:Nitraria tangutorun Bobr., a unique kind of fruit, widely spreads in the Qinghai–Tibet Plateau. In the present study, nine anthocyanins were identified in two variations (purple fruit and red fruit) of N. tangutorun by HPLC/DAD–ESI/MS. Cyanidin-3-O-(trans-p-coumaroyl)-diglucoside (215.76±22.91mg of Mv3G5G equivalent per 100g of fresh weight) and pelargonidin-3-O-(p-coumaroyl)-diglucoside (5.13±0.35mg of Mv3G5G equivalent per 100g of fresh weight) were the main anthocyanins in the purple and red fruits respectively. In addition, most of the anthocyanins were acylated by coumaric acid, and the rare anthocyanins that naturally presented a coumaric acid in both cis and trans configurations have been detected. Furthermore, the extract of the two variations showed significantly different antioxidant activity (p
