摘要: 为初步探究肉苁蓉(荒漠肉苁蓉和管花肉苁蓉)及混淆品(盐生肉苁蓉、沙苁蓉、兰州肉苁蓉和弯管列当)粗多糖的体外抗氧化能力,本研究测定了其粗多糖对DPPH·、·OH、ABTS·的清除能力和总抗氧化能力(T-AOC)。采用Topsis法综合分析各项指标,整体评价6种药用植物粗多糖的体外抗氧化能力,评价结果显示,6种药用植物粗多糖体外抗氧化能力的排序依次为:管花肉苁蓉>弯管列当>荒漠肉苁蓉>兰州肉苁蓉>沙苁蓉>盐生肉苁蓉。其中,弯管列当和兰州肉苁蓉粗多糖体外抗氧化能力接近正品肉苁蓉。本研究综合评价了肉苁蓉及混淆品6种药用植物粗多糖的体外抗氧化能力,对肉苁蓉等相关药用植物资源的综合开发具有借鉴意义。

Abstract:

To initially investigate the antioxidant capacity in vitro of crude polysaccharides from Cistanche(Cistanche deserticola and C. tubulosa) and its adulterants (C. salsa,C. sinensis,C. lanzhouensis and Orobanche cernua),their ability of crude polysaccharides to scavenge DPPH·,·OH,and ABTS· and their total antioxidant capacity (T-AOC) were determined respectively.Simultaneously,the Topsis method was used to comprehensively analyze the antioxidant capacity in vitro of those crude polysaccharides from six medicinal plants.As a result,the order of antioxidant capacity in vitro of their crude polysaccharides was as follows:C. tubulosa> O. cernua> C. deserticola> C. lanzhouensis> C. sinensis> C. salsa.Among them,the antioxidant capacity in vitro of crude polysaccharides from O. cernua and C. lanzhouensis is close to authentic Cistanche.This study comprehensively evaluated the antioxidant capacity in vitro of crude polysaccharides from six medicinal plants of Cistanche and its adulterants,which can provide a significant reference for the comprehensive development of related medicinal plant resources such as Cistanche and its adulterants.

Key words: Cistanche, adulterants, crude polysaccharides, antioxidant capacity
