Comparison of extraction techniques on extraction of gallic acid from stem bark of Jatropha curcas

In this study, effectiveness of three different commonly applied extraction techniques for the determination of gallic acid in the stem bark of Jatropha curcas has been compared. The three different techniques that were used are namely as Soxhlet extraction, Ultrasonic-Assisted Extraction (UAE) and...
