초록

Rehmannia glutinosa root and Saururus chinensis plant have been widely used in natural traditional medicines. This study was conductedto investigate the effect of the content of the main components of R. glutinosa root and S. chinensis plant by extraction method. Theresults of comparative analysis of extraction yield, total flavonoid, and polyphenol content by extraction method indicated that extractionyield had the best performance with hot water extraction for R. glutinosa and ultrasound-assisted extraction for S. chinensis. The totalflavonoid and polyphenol content had the best performance with maceration extraction for R. glutinosa and ultrasound-assisted extractionfor S. chinensis. ABTS and DPPH activity was excellent with maceration extraction for both R. glutinosa and S. chinensis. The analysisof the main components showed that maceration extraction was most effective for both S. chinensis and R. glutinosa. Specifically, macerationextraction of R. glutinosa yielded 1.5 times more than conventional ultrasound-assisted extraction.
