不同寒旱地域黑枸杞花青素成分及抗氧化性分析
Analysis of anthocyanidins components of black wolfberries from cold and arid areas and their antioxidant activity
摘要
Abstract
Black wolfberry(Lycium ruthenicum Murr.)from three typical cold and drought areas--Dulan county and Qaidam county of Qinghai province,and Huade county of Inner Mongolia--were selected as experimental materials.Anthocyanin components and types were analyzed using high performance liquid chromatography-electrospray ionization-triple stage quadrupole/mass spectrometer(HPLC-ESI-TSQ/MS).Antioxidant capacities of anthocyanins were assessed.The results showed that two types of anthocyanins and three types of anthocyanins glycosides were detected in black wolfberry from all three regions.However,significant regional differences were observed in anthocyanidins content.The highest total anthocyanidins content was found in Huade county(40.078 mg/L).Samples from Huade showed the highest DPPH·and·O2-scavenging ability of 2.24,3.27 mg/mL,respectively.In terms of·OH radical scavenging ability,the Qaidam sample exhibited the strongest effect(4.11 mg/mL).All three samples demonstrated significantly stronger DPPH·scavenging activity compared to·OH and·O2-free radical.and the radical scavenging rates showed a dose-effect relationship with extract concentration.This study provides preliminarily insights into anthocyanidins composition and antioxidant variations of black wolfberry grown in different cold and arid regions,offering a scientific foundation for the targeted development and utilization of black wolfberry resources in China.关键词
