摘要
以竹叶兰为试材,研究了其不同部位提取物对DPPH自由基的清除活性的影响。结果表明:竹叶兰不同部位提取物均有很强的抗氧化活性;竹叶兰的根、茎、叶的IC50值分别为0.03869、0.04976、0.02966mg/mL;根、茎、叶最大清除率分别为:85.26%、84.75%、90.41%;竹叶兰不同部位抗氧化能力顺序为叶>根>茎。
Taking Arundina graminifolia as material, the scavenging activities of different part extracts from it on DPPH free radical was investigated. The results showed that different parrs of Arundina graminifolia all had strong antioxidant activity. The ICs0 values of root, stem, leaves were 0. 03869,0. 04976,0. 02966 mg/mL, respectively; the maximum scavenging rate was 85.26M for root, 84. 75% for stem and 90. 41% for leaves; the antioxidant capacity was observed in the following order： leaves〉root〉stem.
