Tóm tắt

The Central composite design (CCD) of response surface methodology (RSM) was used to investigate the effects of three factor as extraction temperature (°C), extraction time (min) and ethanol concentration (%) of Launaea sarmentosa leaves on the responses: total phenolic content (TPC) and total flavonoid content (TFC). The optimal conditions obtained from response RSM were 90% v/v for
the solvent ratio, 54°C for extraction temperature and 110min for extraction time. The experimental values of TPC and TFC were 318.85±0.32 mgGAE/g, 8.21±0.14 mgCE/g.
