| Abstract: | Objective: To establish optimal extraction technology of gallic acid and total polyphenols from loropetalum chinense. Method: With the content of gallic acid and total polyphenols as indexes, four different methods(refluxing extraction, leakage extraction, soxhlet extraction and ultrasonic extraction) were investigated,and orthogonal test was adopted to optimize extraction process parameters,including solvent, ratio of solid-liquid, extraction time and extraction times. Result: Refluxing extraction method was optimal extraction technology, optimum condition was as follow: 8 times the amount of 60% ethanol, extracted three times with 2 hours each time. Conclusion: This extraction process showed higher yield and good stability of gallic acid and total polyphenols,it was available for industrial production. |
