In recent years there has been an increasing interest in compounds present in foods that may prevent or slow the progression of chronic illnesses, such as cardiovascular disease, osteoporosis and cancer. Saponins have been reported to have important time-dependent anti-cancer properties. We have
Glycyrrhetinic acid, as pentacyclic triterpenoid aglycone, is the major functional component in licorice which mainly exists in the form of functional glycosides in licorice. The introduction of sugar moiety to the C-3 OH of GA to yield glycosylated derivatives has been reported, but the late-stage
Soybeans (Glycine max L. Merill) and soy-based food products are major dietary sources of saponins. An oleanane triterpenoid saponin, soyasaponin Bh (1) containing a unique five-membered ring with a hemiacetal functionality together with seven known saponins were isolated from soybeans. Their
Soyasaponins I and III are monodesmodic oleanane triterpenoids that are thought to be one of the main potentially bioactive saponins found in soy ( Glycine max ) and related products. An extract that contained a majority of the soyasaponins as I (62%) and III (29%) was studied in a hepatocarcinoma
Lotus japonicus is an important model legume plant in several fields of research, such as secondary (specialized) metabolism and symbiotic nodulation. This plant accumulates triterpenoids; however, compared to Medicago truncatula and Glycine max, less information regarding its composition, content,
Soyasaponins are a group of complex and structural diverse oleanane triterpenoids found in soy (Glycine max) and other legumes. They are primarily classified into two main groups - group A and B - based on the attachment of sugar moieties at positions C-3 and C-22 of the ring structures. Group A
Triterpenoid saponins are naturally occurring structurally diverse glycosides of triterpenes that are widely distributed among plant species. Great interest has been expressed by pharmaceutical and agriculture industries for the glycosylation of triterpenes. Such modifications alter their taste and
Triterpene saponins are a diverse group of biologically functional products in plants. Saponins usually are glycosylated, which gives rise to a wide diversity of structures and functions. In the group A saponins of soybean (Glycine max), differences in the terminal sugar species located on the C-22
Root exudates are plant metabolites secreted from the roots into the soil. These exudates are involved in many important biological processes, including acquisition of nutrients, defense and signaling to rhizosphere bacteria, such as isoflavones of soybean crucial for the symbiosis with rhizobium.
Saponins can be found in more than one hundred plant families and in some marine animals. However, chemical investigation of soybean (Glycine max L. Merrill) saponins has begun only as recently as the 1970s. Here we focus on the chemical structure, the content, and biological activity of soybean
Triterpenoid saponins are one of the most highly accumulated groups of functional components in soybean (Glycine max) and the oxidative reactions during their biosynthesis are required for their aglycone diversity. Natural mutants of soyasaponins in wild soybean (Glycine soja) are valuable resources
Plant uridine 5'-diphosphate glycosyltransferases (UGTs) influence the physiochemical properties of several classes of specialized metabolites including triterpenoids via glycosylation. To uncover the evolutionary past of UGTs of soyasaponins (a group of beneficial triterpene glycosides widespread
