Chemical study on Sophora tonkinensis was written by Deng, Yinhua;Xu, Kangping;Zhang, Wei;Tan, Guishan. And the article was included in Tianran Chanwu Yanjiu Yu Kaifa in 2005.Product Details of 6807-83-6 This article mentions the following:
Five compounds were isolated from the roots of Sophora tonkinensis by column chromatog. Their structures were elucidated as L-maackiain (1), trifolirhizin (2), quercetin (3), rutin (4), and isorhamnetin-3-rutinoside (5) on the basis of spectral evidence. Among them, 3 and 5 were isolated from this plant for the first time. In the experiment, the researchers used many compounds, for example, (2S,3R,4S,5S,6R)-2-(((6aR,12aR)-6a,12a-Dihydro-6H-[1,3]dioxolo[4′,5′:5,6]benzofuro[3,2-c]chromen-3-yl)oxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol (cas: 6807-83-6Product Details of 6807-83-6).
(2S,3R,4S,5S,6R)-2-(((6aR,12aR)-6a,12a-Dihydro-6H-[1,3]dioxolo[4′,5′:5,6]benzofuro[3,2-c]chromen-3-yl)oxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol (cas: 6807-83-6) belongs to benzofurans derivatives. Benzofurans are only weakly aromatic in nature and they are cleaved by many oxidative and reductive conditions. Introduction of benzofurans in organic synthesis, particularly drug synthesis, involves generally the use of their metalated species as nucleophiles in addition reactions or in metal-catalysed cross-coupling reactions.Product Details of 6807-83-6
