New Sucrose Derivatives from the Bark of Securidaca longipedunculata

Journal of Natural Products, 1993
Two new bitter principles were isolated from the bark of Securidaca longipedunculata (Polygalaceae) and identified as beta-D-(3,4-disinapoyl)fructofuranosyl-alpha-D-(6-sinapoyl)g lucopyranoside and beta-D-(3-sinapoyl)fructofuranosyl-alpha-D-(6-sinapoyl)gluco pyranoside. The structures were elucidated by a combination of 1H nmr (1D, 2D COSY, 2D HOHAHA),

Securigenin glycosides as hypoglycemic principles of Securigera securidaca seeds

Journal of Natural Medicines, 2016
Seeds of Securigera securidaca (Fabaceae) are used in Iranian folk medicine as an antidiabetic treatment. In this study, the antihyperglycemic activity of chloroform and methanol fractions (CF and MF) from S. securidaca seed extract was investigated and their bioactive constituents were identified. The antidiabetic effects of fractions were assessed by
