干巴菌抗氧化活性研究

Study on Antioxidant Activity of Wild Mushroom Thelephora Ganbajun Zang

目的研究干巴菌的抗氧化活性.方法采用DPPH自由基清除法对野生食用菌干巴菌提取物的体外自由基清除作用进行研究.结果干巴菌的乙酸乙酯和甲醇提取物活性较好,IC50分别为0.025,1.69 mg/mL.结论干巴菌乙酸乙酯提取部分比芦丁(IC50=0.063 mg/mL)抗氧化活性强.

Objective To study the antioxidant activity of wild mushroom ganbajun in Yunnan. Method DPPH radical scavenging activity in vitro method was used to study the antioxidant activity of thelephora ganbajun zang. Result It was found that the EtOAc extract and the MeOH extract exhibit good scavenging actions （IC50 = 0.025, 1.69 mg/mL） than the others. Conclusion EtOAc extract from ganbajunis stronger than rutin （IC50 = 0.063 mg/mL）.
