Optimization for extraction on total phenolic contentand radical scavenging capacity of henna (Lawsonia inermis) stems using response surface methodology

This study aimed to optimise potential extraction conditions using response surface methodology (RSM) for yielding maximum levels of total phenolic content (TPC) and 2,2-diphenyl-1-picryhydrazyl radical (DPPH•) scavenging capacity of henna (Lawsonia inermis) stems. The ranges for selected independen...
