Abstract

Polyscias fruticosa (L.) Harms root extracts were obtained and separated using ultrasound-assisted extraction (UAE) with the preset optimal parameters, such as solvent/solid (SS) ratio (50/1, mL g–1), ethanol concentration (40%, v/v), temperature (45 °C), and extraction time (20 min). The best values of the total phenolic content (TPC) and antioxidant capacity (AC) of the extracts under these extraction conditions were 2.13 ± 0.02 mg of gallic acid equivalents (GAE) per gram of dry sample weight (DW) for TPC and 78.13 ± 0.25% for AC. In addition, the structure of the plant material was examined by scanning electron microscopy (SEM): it was revealed that the structure of the residues changed completely as a result of the ultrasound treatment compared to the initial material.
超声辅助提取茯苓中酚类化合物的研究危害根
多糖(L.)采用超声辅助提取法(UAE),在溶剂/固体(SS)比(50/1,mL g-1)、乙醇浓度(40%,v/v)、温度(45°C)、提取时间(20 min)的条件下进行分离。最好的总酚含量值(TPC)和抗氧化能力(AC)的提取这些萃取条件下分别为2.13±0.02毫克的没食子酸当量(GAE)每克干样品重量(DW) TPC和78.13±0.25% AC。此外,植物材料的结构是由扫描电子显微镜(SEM)研究:据透露,残留的结构彻底改变了由于超声波治疗相比,最初的材料。
