Optimization of Polyphenols from Moringa oleifera Lam. Leaves by Ultrasound-assisted Extraction Using Response Surface Methodology and Their Antioxidant Activities
摘要
Abstract
In order to obtain the best ultrasound-assistedextracting conditions for polyphenols fromMoringa oleifera Lam. leaves, and clarified their antioxidant activities. Response surface methodology was used to explore the effects of ultrasonic power, extraction time, extraction temperature, and solid to liquid ratio on extraction rate. Moreover, the reducing power, the DPPH radical scavenging activities and the O2-· scavenging effect of polyphenols fromMoringa oleifera Lam. leaves were also investigated. The results showed that the best extraction condition were as follows: the extraction time of 19.5 min, the solid to liquid ratio of 1:30 (g/mL), the extraction temperature of 20.2℃, and the ultrasonic power of 250 W. Under the optimal extractions, the extraction rate of phycoerythrin was (25.14 ± 0.46) mg/g. In addition, the polyphenols fromMoringa oleifera Lam. leaves. have strong anti-oxidative, and the reducing power, the DPPH radical scavenging activities and the O2-· scavenging effect were 81.25%, 94.15% and 75.05% ofL-ascorbic acid, respectively. This research could provide the theoretical basis for higher preparation and antioxidants development ofMoringa oleifera Lam. leaves.关键词
