Abstract:

The extraction technology of xanthoceraside from Xanthoceras sobifolia Bunge husks was optimized through singlefactor test and orthogonal test with extract yield and content of xanthoceraside in extract as the evaluation indexes. The obtained best extraction process is as follows: twice extracting powdered Xanthoceras sorbifolia Bunge husks twice with 7 times volume of 70% ethanol for 5 h under reflux in the thermostatically controlled water-bath. This extraction process is rational, stable and feasible, and can offer useful information for industrial production.

Key words: Xanthoceras sorbifolia Bunge, xanthoceraside, orthogonal test
