Optimization of Extraction Process for Polysccharides from Whole Plants of Gonostegia hirta （BL.） Miq.
摘要
Abstract
Objective： To find optimal conditions for the extraction of polysaccharides from whole plants of Gonostegia hirta （BL;） Miq. Methods： Solvent reflux extraction was used for polysaccharide extraction. Five parameters that influence extraction efficiency were investigated using one-factor-at-a-time and orthogonal array design methods, and three main ones were opti- mized based on a quadratic rotation-orthogonal composite experimental design. Results： In decreasing order of their effect on extraction efficiency, five influential parameters were ranked as extraction temperature 〉 solvent-to-solid ratio 〉 extraction time 〉 extraction number 〉 soaking time. Their optimal levels were 96.26 ℃, 27.28： 1 （mL/g）, 109.20 min each time, 2 and 90 min, respectively, resulting in an extraction yield of 25.121%. Conclusion： Quadratic rotation-orthogonal composite experimen- tal design permits reasonable optimization of polysaccharide extraction from Gonostegia hirta （BL.） Miq.关键词
