Microwave Assisted Extraction of Cyanotis beddomei

Mahendran TR, Maheswaran S, John JT and Haarindraprasad R

Cyanotis beddomei is being extracted via Microwave-Assisted Extraction (MAE) method. The chosen variables for the extraction were methanol proportion, extraction time, extraction temperature and ratio of liquid to solid. The optimum extraction conditions were methanol of 70% (v/v), extraction time of 30 min, extraction temperature of 70°C and liquid to solid ratio of 20 mL/g. Under these conditions, 13.31 mg/g total plant extracts were obtained by Microwave Assisted Extraction (MAE). The results showed that all the chosen variables for the MAE were significant on the yield of crude extract while the most important variable was the extraction time and solid to liquid ratio.
