Two new bidesmoside triterpenoid saponins which were identifed as 28-O-β-D-xylopyranosyl(1→3)-β-D-xylopyranosyl(1→4)-α-L-rhamnopyranosyl(1→2)-[α-L-rhamno-pyranosyl(1→3)]-β-D-fucopyranosyl gypsogenin 3-O-β-D-glucopyranosyl (1→2)-β-D-glucopyranosiduronic acid (C1) and 28-O-β-D-xylopyranosyl(1→4)-α-L-rhamnopyranosyl (1→2)-[α-L-rhamnopyranosyl(1→3)]-β-D-fucopyranosyl gypsogenin 3-O-β-D-gluco-pyrano...
The impact of triterpenoid saponins isolated from soybeans on suppression of colon cancer cell proliferation was evaluated. Experiments were conducted to determine the effects of a purified soybean B-group saponin extract on cell proliferation, cell-cycle distribution and programmed cell death in cultures of human HCT-15 colon adenocarcinoma cells. Treatment of cells with the soyasaponins at co...
Saponins, a group of glycosidic compounds present in several plant species, have aglycone moieties that are formed using triterpenoid or steroidal skeletons. In spite of their importance as antimicrobial compounds and their possible benefits for human health, knowledge of the genetic control of saponin biosynthesis is still poorly understood. In the Medicago genus, the hemolytic activity of sap...
Bacopa monnieri has been used in Ayurvedic medicine to improve memory and cognition. The active constituent responsible for its pharmacological effects is bacoside A, a mixture of dammarane-type triterpenoid saponins containing sugar chains linked to a steroid aglycone skeleton. Triterpenoid saponins have been reported to be transformed in vivo to metabolites that give better biological activit...
In this study, the efficient micropropagation protocol of Astragalus mongholicus Bunge was established and also triterpenoid saponin polysaccharide content in ethanol, methanol aqueous extracts different samples were determined by using spectrophotometric methods to investigate whether biologically active compounds depends on stage development plant during vitro culture. The total saponins poly...
