Yongfang original Piper longum with supercritical extraction of piperine, ultrasonic solvent extraction rate increased more than 7.3%, extract impurities, without the filter can be directly hplc analysis

Yuan yongfang used supercritical fluid extraction of long pepper extract piperine, than the solvent extraction rate improved by ultrasonic wave 7.3%, extract impurities less directly without filtering for HPLC Analysis

Will be originally forever fragrant with the supercritical extract long pepper in the piperine, the extraction rate enhanced 7.3% compared to the solvent ultrasonic wave law, extracts the impurity to be few, cannot carry on the HPLC analysis directly after the filtration

The original Wing Fong used supercritical extraction projectile in quiz pepper alkali, solvent extraction rate than ultrasonic Act had improved 7.3 % impurity, extract, without a filter can be directly carried out analysis HPLC
