| optimized extraction of resveratrol from arachis repens handro by ultrasound and microwave: a correlation study with the antioxidant properties and phenol contents. | the vegetal species arachis repens, commonly known as peanut grass, was studied and, for the first time, we detected the presence of the bioactive compound trans-resveratrol (t-rsv). we compared the efficiency of three different methodologies (conventional maceration [cm], ultrasound-assisted extractions [uae], and microwave-assisted extractions [mae]) concerning total phenolics (tp) and resveratrol (t-rsv) content, followed by antioxidant activity (aa) evaluation. by cm, at 1 h, the highest rsv ... | 2016 | 28116343 |
