Antioxidation and Antibacterial Property of Total Flavonoids from Lilium pumilum Bulb
In this research,we studied the antioxidant and antimicrobial of total flavonoids extracted from Lilium pumilum bulb.Three antioxidant assays in vitro (super oxygen anion scavenging capacity,hydroxyl free radical scavenging capacity and DPPH radical scavenging capacity) were used to evaluate the antioxidant activity of total flavonoids from Lilium pumilum bulb.The antibacterial activity was evaluated by stiletto method.The results showed that the scavenging rate of total flavonoids from Lilium pumilum bulb on superoxide anion was 63.27％,the scavenging rate of hydroxyl free radical was 70.36％ and the scavenging rate of DPPH free radical was 52.83％.Those even better than BHT scavenging capacity in the experimental concentration range,and it on nine kinds of bacteria have different degrees of inhibition.It indicated that the flavonoids extracted from Lilium pumilum bulb can be used as a natural antioxidant and antibacterial agent extensively.
