  Supercritical carbon dioxide (SC-CO2) extraction was used to obtain the bioactive flavonoid compounds of Strobilanthes crispus (Pecah Kaca). Process variables namely pressure, temperature and co-solvent flow rate were studied for optimization of the extraction yield and bioactive flavonoid compound of S. crispus by response surface methodology following a Box Behnken design of experiments. HPLC was performed to determine the major bioactive flavonoid compounds from S. crispus. The optimum value of yield extraction (6.55%) was obtained at pressure 200 bar, 50°C temperature and co-solvent flow rate of 5 g/min. Under the optimum conditions, eight flavonoid compounds were identified namely (+)-catechin, (-) epicatechin, rutin, myricetin, luteolin, apigenin, naringenin and kaempferol. The experimental extraction yield is in good agreement with the.. View More»
