Optimization of Extraction Conditions of Active Constituents from Siraitia Grosvenorii

Abstract:

Article Preview

The conditions of cascade extraction and isolation of some active constituents from Siraitia grosvenorii were optimized. The active constituents were extracted by ultrasonic extraction and isolated by chromatography; the obtained active constituents were determined by HPLC and/or spectrophotometry etc. The yields of the active constituents were as follows, mogroside 3.97% (purity 91.84%), polyphenol 3.45%, free polysaccharide 12.53%, free oligosaccharide 11.96%, combined polysaccharide 2.29%, combined oligosaccharide 2.88%, amino acids 6.54% and alkaloid 7.06%. This extraction process could be used as a guideline for the multi-utilization of Siraitia grosvenorii.
