CHEMICAL STUDY FOR SECONDARY METABOLITES IN THE ROOTS OF POLYGONUM STRINDBERGII SCHUST. IN BULL. HERB. BOISS. SER

Hong-yan Ma, Li-rong Nie, Shun Yao.




Abstract

To study the secondary metabolites in Polygonum Strindbergii Schust. in Bull. Herb. Boiss. ser. in Yunnan province of China, the ground
roots were extracted with IL (ionic liquid) aqueous solution, then partitioned by organic solvents and isolated by column chromatography
repeatedly. Eight compounds were obtained and their structures were identified by spectral methods, which were found from the plant for the
first time. Moreover, the key conditions of ILs application were investigated, which are wished to be helpful for related researchers. The
plant is supposed to be further utilized and developed as a meaningful natural resource in the genus.

Key words: Polygonum Strindbergii Schust. in Bull. Herb. Boiss. ser., secondary metabolites, Ionic liquids, separation and identification
