| 中文摘要 | ultrahigh pressure technique was employed to extract ginsenosides from roots of ginseng (panax ginseng c.a. meyer). the optimal conditions for ultrahigh pressure extraction (upe) of total ginsenosides were quantified by uv-vis spectrophotometry with the ginsenoside re as standard, the signal ginsenosides were quantified by hplc and elsd with ginsenosides re, rg(1), rb-1, rc and rb-2 as standards. orthogonal design was applied to evaluate the effects of four independent factors (extraction pressure, extraction temperature, extraction time and ethanol concentration) on the yield and 1,1-diphenyl-2-picrylhydrazyl (dpph) radical scavenging activity of ginsenoside, which are based on microwave extraction (me), ultrasound extraction (ue), soxhlet extraction (se) and heat reflux extraction (hre) method. the results showed that upe method can produce ginsenoside with the highest yield and the best radical scavenging activity compared to other used ones. scanning electron microscopic (sem) images of the plant cells after ultrahigh pressure treatment was obtained to provide visual evidence of the disruption effect. |
