摘要:
应用密闭微波辅助提取法提取玄参中有效成分玄参苷,考察了微波提取条件(包括溶剂、样品粒径、提取时间、固-液质量体积比和提取次数等)对玄参中提取玄参苷收率的影响,结果表明:溶剂为70%乙醇,玄参的粒径为180目,提取时间为10 m in,料液比为1∶20及提取次数为2次时,玄参苷的提取率最佳。并且与常压微波辅助提取法、超声波提取法及索氏提取法进行了比较,本法具有快速、高效、绿色环保的优点。
Abstract:
The harpagoside from the rad ix scrophulariaew ere ex tracted by means ofm icrow ave-assisted and airtight so lvent ex traction. The influence of some operat ion cond itions, such as so lven,t samp le particle size, m icrow ave irradiat ion tim e, the ratio of samp le w eight to so lvent vo lume and t imes of ex tract ion, on the extraction y ield of harpagoside is studied. The experimental resu lts show that the h ighest ex traction y ield is obta ined when the extraction solvent is 70% ethano,l the sample particle size is 180 mesh, the m icrow ave irrad iation tim e is 10m in , the ratio o f samp le w eight to solvent vo lum e is 1B20 and the times o f the extraction is 2. Compared w ith the m icrow ave-assisted ex traction in norma l pressure, the ultrason ic extract ion and the soxh le t ex traction, them icrow ave-assisted extraction in c losed conta iner is fas,t effic ient and green.
