Abstract:
Objective:To optimize the flash extraction method for polygonatum saponin by orthogonal design. Methods: The ex-traction technology was optimized by L9 (34 ) orthogonal test based on the results of single factor experiments. The optimized conditions were as follows:the material liquid ratio was 1 ∶20, the extraction voltage was 100 V, the extraction time was 40s, and the herbs were extracted 3 times (40 s per time). Results:The ratio of material to liquid had significant effect on the extraction rate,and under the a-bove extraction conditions, the extraction amount of polygonatum saponin reached up to (38. 92 ± 0. 67) mg·g-1 . The order of extrac-tion rate was flash extraction >ultrasonic extraction> ethanol extraction. Conclusion:The flash extraction is beneficial to the extrac-tion of polygonatum saponin.
