Abstract:
To investigate the antioxidant activities and antimicrobial activities from tuberous root of Siraitia grosvenorii(swingle)，the total phenolics and flavonoids from tuberous root of Siraitia grosvenorii (swingle) were extracted with different concentrations of ethanol.The extractions were applied into scavenging their oxidant capacities，such as superoxide anion radicals (O?[TX-*4]2)，hydroxyl radicals (?OH)，DPPH? radicals,ABTS+?，ferric reducing antioxidant power and total reducing power.They also were applied into inhibiting the microbial activities.Six kinds of microbe were selected.The results showed that the contents of total phenolics and flavonoids were 5.79% and 8.17%，respectively，when the optimum ethanol concentration was 80%.The extraction had strong antioxidant activities and antimicrobial activities.Moreover，the activities of the extraction were contacted with contents of the extraction.Compared with the vitamin C，the antioxidant activities of extraction from tuberous root of Siraitia grosvenorii with 80% ethanol was lower.This study could provide a certain scientific basis for development of Siraitia grosvenorii(swingle).
