Saponins are sterols or triterpene glycosides that are widely distributed in plants. The biosynthesis of soybean saponins is thought to involve many kinds of glycosyltransferases, which is reflected in their structural diversity. Here, we performed linkage analyses of the Sg-3 and Sg-4 loci, which may control the sugar chain composition at the C-3 sugar moieties of the soybean saponin aglycones...

Background: Holothuroids (sea cucumbers) are members of the phylum echinodermata, which produce saponins. Saponins exhibit a wide spectrum of pharmacological and biological activities. In this study, we isolated the crude saponins from the body wall of the dominant Iranian species of sea cucumber, Holothuria leucospilota (H. leucospilota). The purpose of this study was to confirm the presence o...

Plant saponins have been used as additives to mitigate methane emissions originated from enteric fermentation of ruminant animals. Most of the studies however were based on in vitro techniques, and only limited studies were directly conducted on the animals. Inconsistencies of saponin effects on methane emissions have been previously observed, which might be related to their levels in rations. ...

Objective: Moringa oleifera Lam. is the most widely cultivated species of the monogeneric family Moringaceae and has an impressive range of medicinal uses with high nutritional value. In this study saponin was isolated from Moringa oleifera pods. Methods: Thin layer chromatography (TLC) was performed using a mobile phase of Chloroform: methanol: H2O (7:3:1) on silica gel glass plates. High perf...

BACKGROUND Because of the increasingly concern of consumers and public policy about problems for environment and for public health due to chemical pesticides, the search for molecules more safe is currently of great importance. Particularly, plants are able to fight the pathogens as insects, bacteria or fungi; so that plants could represent a valuable source of new molecules. RESULTS It was o...

Saponin-rich GM extract was prepared by refluxing 25 g of GM with 250 ml of EtOH/H2O (1:1, v/v) for 3 h then filtering and distilling EtOH at 50 C. The refluxed extract was partitioned with equal volume of BuOH obtaining crude saponin-rich GM extract with 4.8 ± 0.6% DM of GM that was purified by RP-HPLC eluting 20%, 60% and 100% MeOH fractions with 2.04 ± 0.32%, 0.91 ± 0.16% and 1.55 ± 0.15% DM...

objective(s):marine organisms are known as a potential source of natural products, which contain bioactive substances with therapeutic properties. sea cucumbers are prominent among marine organisms because of their dietary and therapeutic applications. in addition, they have capacity of synthesizing saponins molecules and other metabolites with therapeutic properties such as antitumor, antimicr...

Abstract Although saponin originated from plants has been used to control methanogenesis performed by archaea methanogens in the rumen, its effect inconsistent. The objective of this study was evaluate dietary on enteric methane emission and nutrient digestibility ruminants across various studies employing a meta-analysis method. A database developed integrating data 17 that 11 articles. Differ...

Extracts of the Quillaja saponaria tree contain natural surfactant molecules called saponins that very efficiently stabilize foams and emulsions. Therefore, such extracts are widely used in several technologies. In addition, saponins have demonstrated nontrivial bioactivity and are currently used as essential ingredients in vaccines, food supplements, and other health products. Previous prelimi...
