Optimization of Ultrasonic-Assisted Extraction of Polyphenolic and Flavonoids from Labisia pumila

This work presents an optimization study of polyphenol extraction from L. pumila with aid of sonication. The polyphenol content was evaluated using Singleton�s method and aluminium chloride colorimetric assay. The two level factorial design 2LF was used to screen the significance of the extraction p...
