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 ...

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.

Saponins are complex multifunctional molecules made up of an aglycone (steroid or triterpene) and of one or several chains of sugars. They are polar and their isolation and separation require solvents and adsorbents of high polarities, sometimes associated with moderately high temperatures.

Chemical Synthesis of Saponins
2014Saponins are a large family of amphiphilic glycosides of steroids and triterpenes found in plants and some marine organisms. By expressing a large diversity of structures on both sugar chains and aglycones, saponins exhibit a wide range of biological and pharmacological properties and serve as major active principles in folk medicines, especially in ...

Saponins are a diverse family of secondary metabolites that are produced by many plant species, particularly dicots. These molecules commonly have potent antifungal activity and their natural role in plants is likely to be in protection against attack by pathogenic microbes. They also have a variety of commercial applications including use as drugs and

The term saponin comes from the Latin word sapo, meaning "soap", reflecting a readiness to form stable soap-like foams in aqueous solutions. The biological role of saponins is not completely understood, but they are generally considered to be part of a plant's defence 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 ...

Abstract This chapter focuses on saponins in quinoa (Chenopodium quinoa), particularly on their chemical structures, biosynthesis, and industrial applications. The genetic basis of saponin content, methods for saponin analysis, and techniques for the removal of saponins from seeds are also covered.
