Extraction Technology of Volatile Oil from Leaf of Chimonanthus Salicifolicus Hu and Scavenging Capacity against Alkyl Radical
摘要
Abstract
[ Objective ] The ultrasonic-assisted extraction technology of volatile oil from leaf of Chimonanthus Salicifolicus Hu was investigated, and the scavenging capacity against alkyl radical of volatile oil was studied. [ Method] The orthogonal experiments were carried out to study extraction technology of volatile oil with ultrasonic time, extraction time, and material-to-liquid ratio. The scavenging capacity against alkyl radical of 25% volatile oil was studied with 1.00 mg/ml Vc as the positive control. [Result] The optimal extraction technology was obtained as ultrasonic time of 2 h, extraction time of 8 h, and material-to-liquid ratio of 1:9 g/ml. Under the optimal conditions, the extraction yield of volatile oil was.determined to be 1.67%. The IC50 value of scavenging capacity against alkyl radical was 208. 09 μl. [ Conclusion] The volatile oil from leaf of Chimonanthus Salicifolicus Hu was rich, and its scavenging capacity against alkyl radical was good. So, it is worth to develop for application.关键词
