三七多糖的微波辅助提取工艺
Microwave Assisted Extraction of Polysaccharides from Panax notoginseng
摘要
Abstract
Microwave assisted extraction of polysaccharides from Panax notoginseng was optimized using single factor experiments and the orthogonal test. The mechanism underlying microwave assisted extrac-tion was identified by laser diffraction particle sizing analysis,and the monosaccharide composition of pol-ysaccharides was characterized by thin-layer chromatography. The optimal conditions for microwave assis-ted extraction were obtained:microwave duration of 8 min,soaking time of 60 min,ratio of liquid to solid of 30 mL/g,and particle size of 200 meshes.The extraction yield of microwave assisted extraction(21.0 mg/g) was significantly higher than that of conventional extraction(12.7 mg/g). Thin-layer chromatog-raphy and solubility of polysaccharides were studied. Microwave assisted extraction was superior to con-ventional extraction in terms of the extraction yield. The possible reason was that microwave radiation fa-cilitated the swelling of plant samples, and their structure became loose, which led to the exudation of polysaccharides. Polysaccharides from P. notoginseng were mainly composed of three monosaccharides, which were glucose,galactose and arabinose,while the pH value greatly affected solubility of polysaccha-rides from P. notoginseng.关键词
