soyasaponin/glycine max

A new high-throughput method was developed for the simultaneous analysis of isoflavones and soyasaponnins in Soy (Glycine max L.) products by high-performance thin-layer chromatography with densitometry and multiple detection. Silica gel was used as the stationary phase and ethyl

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

Triterpene saponins are a diverse group of compounds with a structure consisting of a triterpene aglycone and sugars. Identification of the sugar-transferase involved in triterpene saponin biosynthesis is difficult due to the structural complexity of triterpene saponin. Two glycosyltransferases from

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.

We investigated how soyasaponins (SS), which had been isolated from soybeans (Glycine max Merrill, seeds), influenced lipid peroxidation. The in vivo reduction in hepatic lipid peroxidation in mice intraperitoneally injected with total soyasaponins (TSS) was comparable to that which has been

Micellar electrokinetic capillary chromatography using sodium cholate as the micellar phase has been investigated for characterization of hapten-protein conjugates. Special focus has been placed on the hapten soyasaponin I which is a quantitatively dominating glycoside in seeds of several legumes

Soybean [Glycine max (L.) Merr.] seeds contain soyasaponin B, which has putative health benefits. Studies were conducted in multiple environments in Quebec, Canada to determine the effects of genotypes, environments, and seeding dates on soyasaponin B concentration in mature seeds. A growth chamber

Key message Significant QTL for soyasaponin I, as the major component of the soyasaponin B, have been identified using an RIL soybean population, which could facilitate the development of functional food soybean cultivars. Soyasaponin B forms that are naturally found in soybean (Glycine max [L.]

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

Soyasaponins from soybean (Glycine max) represent promising new potent adjuvants for vaccine research because of their immunostimulating properties and weak hemolytic activity. In the present study, saponin microstructures of soyasaponins (soyasaponin Bb, soyasaponin Ab) with lipid components

Soy (Glycine max, family Leguminosae), which contains isoflavones and saponins as main constituents, is known to exhibit memory-enhancing effects. Therefore, to investigate the role of soyasaponins in memory impairments, we isolated soyasaponins Ab (SA) and Bb (SB) from soybean and measured their

Bioactive soyasaponins are present in soybean (Glycine max). In this study, the isolation of soyasaponins in relatively pure form (>80%) using precipitation, solid phase extraction and reverse phase low pressure liquid chromatography (RP-LPLC) is described. Soy flour soyasaponins were separated from

Soy (Glycine Max Merr, family Leguminosae) has been reported to possess anti-cancer, anti-lipidemic, estrogen-like, and memory-enhancing effects. We investigated the memory-enhancing effects and the underlying mechanisms of soyasaponin I (soya-I), a major constituent of soy. Impaired learning and

The antiviral activities of two saponins, soyasaponin I and II, isolated from soybean (Glycine max Merrill) were studied in vitro against herpes simplex virus type 1 (HSV-1). Soyasaponin II was more potent than soyasaponin I as shown by reduction of HSV-1 production. Soyasaponin II was also found to

Parkinson's disease (PD) can be ascribed to the progressive and selective loss of dopaminergic neurons in the substantia nigra pars compacta, and thus molecules with neuroprotective ability may have therapeutic value against PD. In the current study, the neuroprotective effects and underlying
