Chemical composition and antioxidant capacity of three wild fruits

Author(s): Lin Zhao, Qiang Tian, Xiaona Zhang, Ting Zhang, Mengna Zhang, Lin MA
Abstract: In this study, three wild fruits (Chaenomeles speciosa Nakai, Malus halliana Koehne, Malus micromalus Makino) were extracted with different concentrations of ethanol (50% ethanol, 70% ethanol, 95% ethanol), which provided rich resources of total phenols and total flavonoids. The results showed that the 50% ethanol extract of Cs.n had the highest total phenols content (287.89±14.42 mg/g) and total flavonoids content (44.63±2.32 mg/g). The Cs.n extract for 50% ethanol was demonstrated to have the highest DPPH scavenging ability (EC50 = 0.08±0.01 mg/mL), while its extract for 70% ethanol was ranked with the best ABTS scavenging ability (EC50 = 0.13±0.00 mg/mL). For reducing power assay, the Cs.n extract for 95% ethanol was found with the highest UV absorbance (0.927±0.00). Correlation analysis indicated that there was an extremely significant correlation between total phenols, total flavonoids and antioxidant activity.
