摘要
本文评估了新疆和田策勒县梭梭肉苁蓉、红柳肉苁蓉的不同部位的活性成分含量及抗氧化能力.结果表明:红柳肉苁蓉的总多酚、总黄酮、总糖、毛蕊花糖苷含量均表现为下部含量最高,中部、上部含量递减.其中红柳肉苁蓉下部的总多酚、总黄酮含量(38.35 mg GAE/g DW、35.61 mg RE/g DW)分别为梭梭肉苁蓉下部的2.47、10.95倍.梭梭上部松果菊苷含量在两种肉苁蓉不同部位中最高,为92.93 mg/g DW,两种肉苁蓉下部总三萜含量显著高于上部、中部(P＜0.05),梭梭下部总三萜最多,为6.75 mg OAE/g DW.此外,梭梭肉苁蓉和红柳肉苁蓉均表现出较强的抗氧化性,并且肉苁蓉下部的抗氧化效果最好,其IC50DPPH分别为7.15和5.95 mg/mL,IC50ABTS+分别为5.19和3.28 mg/mL.相关性分析表明,肉苁蓉中的总多酚、总黄酮、原花青素、总糖、毛蕊花糖苷含量与IC50DPPH和IC50ABTS+呈负相关.结果表明,梭梭肉苁蓉上部的松果菊苷含量丰富,红柳肉苁蓉下部的总多酚、总黄酮、总糖、毛蕊花糖苷含量丰富且高于梭梭肉苁蓉对应部位.本文可以为不同产地肉苁蓉标准化及功能性产品深度研发提供理论基础.
Abstract
In this paper,the content of active ingredients and antioxidant capacity of different parts of Hoxylon and Red Willow Cistanche deserticola,from Hotan Cele County,Xinjiang,were evaluated.The results showed that the active substances,including total phenols,total flavonoids,total sugars,and verbascoside of Red Willow Cistanche deserticola,were the highest in the lower part of the plant,and decreased in the middle and upper parts.In terms of total phenols and total flavonoids,the contents of the lower part ofRed Willow Cistanche deserticola(38.35 mg GAE/g DW,35.61 mg RE/g DW)were 2.47 and 10.95 times compared to the lower part of Hoxylon Cistanche deserticola,respectively.The upper part of Hoxylon Cistanche deserticola showed the highest content of echinacoside with 92.93 mg/g DW.And the total triterpene content of the lower part-especially that of Hoxylon Cistanche deserticola was significantly higher than the upper and middle part(P＜0.05),at 6.75 mg OAE/g DW.In addition,it was found that the antioxidant properties of both Hoxylon and Red Willow Cistanche deserticola were strong,and the highest antioxidant capacity was observed in their lower parts(IC50DPPH:7.15 and 5.95 mg/mL;IC50ABTS+:5.19 and 3.28 mg/mL,respectively).As shown in the correlation analysis,the contents of total polyphenols,total flavonoids,proanthocyanidins,total sugars,and verbascoside in Cistanche deserticola were negatively correlated with IC50 DPPH and IC50 ABTS+.The results demonstrated that the content of echinacoside was the most abundant in the upper part of Hoxylon Cistanche deserticola.And the lower part ofRed Willow Cistanche deserticola was rich in total polyphenols,total flavonoids,total sugars and verbascoside,compared to the corresponding part of Hoxylon Cistanche deserticola.This paper lays the theoretical groundwork for the standardization and in-depth development of functional products derived from Cistanche deserticola from various regions.
