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.
