The chemical structure of gleditsia saponin C (GS-C), a major triterpenoid saponin of the fruit capsule of Gleditsia japonica Miq. (Leguminosae), comprised echinocystic acid, eight sugar units and two monoterpenyl groups ((+)2,6-dimethyl- and (+) 2-hydroxymethyl-6-methyl-6-(S)hydroxy-2- trans-2,7-octadienoyl groups).

Saponins and acylated saponins from Dizygotheca kerchoveana
Phytochemistry, 2004Four new triterpenoid saponins were isolated from the leaves and stem of branches of Dizygotheca kerchoveana along with seven known ones. The new saponins were respectively characterized as 3-O-[beta-D-glucopyranosyl-(1-->3)]-[beta-D-glucopyranosyl-(1-->2)]-alpha-L-arabinopyranosyl echinocystic acid, 3-O-[beta-D-glucopyranosyl-(1-->3)]-[beta-D ...

The term saponin comes from the Latin word sapo,meaning "soap", reflecting a readiness to form stablesoap-like foams in aqueous solutions. The biologicalrole of saponins is not completely understood, butthey are generally considered to be part of a plant'sdefence system against pathogens and herbivores,particularly because of their bitter flavour ...

There is now a large body of theory concerning algebraic varieties over finite fields, and many conjectures exist in this area that are of great interest to researchers in number theory and algebraic geometry. This 1995 book is concerned with the arithmetic of diagonal hypersurfaces over finite fields, with special focus on the Tate conjecture and the ...

The Journal of Nutrition, 1995
Saponins, which are present in plants, have been suggested as possible anticarcinogens. They possess surface-active characteristics that are due to the amphiphilic nature of their chemical structure. The proposed mechanisms of anticarcinogenic properties of saponins include direct cytotoxicity, immune-modulatory effects, bile acid binding and ...

Three main saponins were isolated from the seeds of Albizzia lucida. Their structures were established by spectral analyses and chemical and enzymatic transformations as 3-O-[beta-D-xylopyranosyl(1----2)-alpha-L-arabinopyranosyl (1----6)] [beta-D-glucopyranosyl (1----2)] beta-D-glucopyranosyl echinocystic acid; 3-O-[alpha-L-arabinopyranosyl (1----6 ...

It has been found that the water solubilities of saikosaponins, the active principles of Bupleuri radix, are greatly increased in the presence of ginsenoside-Ro, the glucuronide bisdesmoside of oleanolic acid of Ginseng. No solubilizing effect was observed with the neutral dammarane Saponins of Ginseng.

Steroidal alkaloid saponins and steroidal saponins from Solanum surattense
Phytochemistry, 2011A rare 16β-H steroidal alkaloid saponin (1), an avenacoside-type saponin (2), two steroidal saponins (4, 5), one revised-structure steroidal saponin (3) and six known compounds (6-11) were isolated from aerial parts of Solanum surattense Burm. f. Their structures were established on the basis of physical data, as well as by using spectroscopic (HRESIMS,
