Abstract

Anoectochilus formosanus (family Orchidaceae) is a perennial herb that contains many bioactive valuable. In this study, the extract efficiency of bioactive compounds from Anoectochilus formosanus Hayata by microwave-assisted extraction (MAE), ultrasonic- assisted extraction (UAE) treatments, and lactic fermentation in individual and combined impacts were evaluated through the total phenolic content, total polysaccharide content, and antioxidant activity. The results showed that MAE and UAE treatments and lactic fermentation enhanced the effective extraction of bioactive compounds compared to the control samples. The bioactive compound contents from A. formosanus fluid trend differences in individual treatment factors. However, there was no significant difference between these treatment factors in which the fermentation process requires more time to reach the expected extraction efficiency. The ultrasonic pretreatment combined lactic fermentation process would bring many benefits; first, no need for more the MAE treatment; second, reduce fermentation time; third, bring a probiotic source as well as valuable metabolic products from the lactic fermentation process.
