|
|
The purpose of this study is to develop a new preparation process of ginseng (Panax ginseng) flower buds extracts featuring high concentration of ginsenosides Rg2, Rg3, Rg5, F4 and Rh1, red ginseng special components. Chemical transformation from ginseng saponin glycosides to prosapogenin was analyzed by the HPLC. Extracts of ginseng flower buds were processed under several treatment conditions of ultrasonication (at 100oC). The results showed that the quantity of ginsenoside Rg6 increased by over 8.8% at the 16 hours of ultrasonication. Ginseng flower buds ethanol extract compared with other process times. The result of UGF-16 indicates that the ultrasonication processed ginseng flower buds extracts (at 100oC) treated for 16 hours produced the highest amount of ginsenoside F4 (8.833%), Rg3 (2.230%), Rg5 (2.339%) and Rg2 (1.002%).
