Variation in saponin content during the growing season of spotted medic [Medicago arabica (L.) Huds.].

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND Spotted medic [Medicago arabica (L.) Huds.] is a minor forage species containing saponins which are reported to be biologically active. This study assessed the concentration and composition pattern of spotted medic saponins during the growing season and at senescence. The pattern of

Triterpene saponins from the roots of Medicago hybrida.

Numai utilizatorii înregistrați pot traduce articole

Fourteen triterpene saponins (1-14) have been isolated from the roots of Medicago hybrida and their structures elucidated by FAB-MS and NMR analysis. Two of them are new compounds and were identified as hederagenin

Triterpenoid glycosides from the leaves of two cultivars of Medicago polymorpha L.

Numai utilizatorii înregistrați pot traduce articole

The saponin composition of leaves from the Medicago polymorpha cultivars 'Santiago' and 'Anglona' belonging to the botanical varieties brevispina and vulgaris, respectively, was investigated by a combination of chromatographic, spectroscopic, and spectrometric techniques. Several compounds were

New triterpenic saponins from the aerial parts of Medicago arabica (L.) huds.

Numai utilizatorii înregistrați pot traduce articole

The reinvestigation of saponin composition from Medicago arabica from Italy allowed the detection of nineteen (1-19) saponins. All of them were purified by reverse-phase chromatography and their structures elucidated by spectroscopic and spectrometric (1D and 2D NMR; ESI-MS/MS) and chemical methods.

Triterpenoid glycosides from leaves of Medicago arborea L.

Numai utilizatorii înregistrați pot traduce articole

Eighteen triterpene saponins (1-18) from Medicago arborea leaves have been isolated and their structures elucidated by spectroscopic, spectrometric (1D and 2D NMR, FAB-MS, ESI-MS/MS), and chemical methods. They have been identified as glycosides of medicagenic, zanhic, and 2beta-hydroxyoleanolic

Triterpene saponins from aerial parts of Medicago arabica L.

Numai utilizatorii înregistrați pot traduce articole

Eight major triterpene saponins have been isolated from the aerial parts of Medicago arabica and their structures elucidated by FAB-MS and NMR analysis. Three of them are new compounds and are identified as 3-O-(alpha-L-arabinopyranoside) bayogenin, 3-O-(alpha-L-arabinopyranosyl),

Saponins in alfalfa (Medicago sativa L.) root and their structural elucidation.

Numai utilizatorii înregistrați pot traduce articole

Twenty-four saponins have been identified in alfalfa roots, including 13 medicagenic acids, 2 zanhic acids, 4 hederagenins, 1 soyasapogenol A, 2 soyasapogenol B's, 1 soyasapogenol E, and 1 bayogenin glycoside. Ten of the identified compounds, including

Isolation and determination of saponin hydrolysis products from Medicago sativa using supercritical fluid extraction, solid-phase extraction and liquid chromatography with evaporative light scattering detection.

Numai utilizatorii înregistrați pot traduce articole

Saponins are widespread secondary metabolites with various beneficial properties: fungicidal, antibacterial, antiviral, and anticancer. Alfalfa saponin molecules contain mainly: medicagenic acid, hederagenin, bayogenin, and soyasapogenol B. Structural diversity of saponins makes their determination

Chemical investigation of saponins from twelve annual Medicago species and their bioassay with the brine shrimp Artemia salina.

Numai utilizatorii înregistrați pot traduce articole

The saponin and sapogenin composition of the aerial growth of 12 annual Medicago species sampled at full senescence were investigated. Saponins were extracted from the plant material and obtained in a highly pure grade by reverse-phase chromatography, with a yield ranging from 0.38 +/- 0.04% to 1.35

Enhanced triterpene saponin biosynthesis and root nodulation in transgenic barrel medic (Medicago truncatula Gaertn.) expressing a novel beta-amyrin synthase (AsOXA1) gene.

Numai utilizatorii înregistrați pot traduce articole

Triterpene saponins are a group of bioactive compounds abundant in the genus Medicago, and have been studied extensively for their biological and pharmacological properties. In this article, we evaluated the effects of the ectopic expression of AsOXA1 cDNA from Aster sedifolius on the production of

Large-Scale Profiling of Saponins in Different Ecotypes of Medicago truncatula.

Numai utilizatorii înregistrați pot traduce articole

A total of 1,622 samples representing 201 Medicago truncatula ecotypes were analyzed using ultrahigh pressure liquid chromatography coupled to mass spectrometry (UHPLC-MS) to ascertain saponin profiles in different M. truncatula ecotypes and to provide data for a genome-wide

Artefact formation during acid hydrolysis of saponins from Medicago spp.

Numai utilizatorii înregistrați pot traduce articole

Artefact compounds obtained during acid hydrolysis of saponins from Medicago spp. (Fabaceae), have been monitored and evaluated by GC-FID. Their identification has been performed by GC-MS and 1H and 13C NMR. Saponins with different substituents on the triterpenic pentacyclic aglycones were

A genomics approach to the early stages of triterpene saponin biosynthesis in Medicago truncatula.

Numai utilizatorii înregistrați pot traduce articole

The saponins of the model legume Medicago truncatula are glycosides of at least five different triterpene aglycones: soyasapogenol B, soyasapogenol E, medicagenic acid, hederagenin and bayogenin. These aglycones are most likely derived from beta-amyrin, a product of the cyclization of

Activity of saponins from Medicago species against HeLa and MCF-7 cell lines and their capacity to potentiate cisplatin effect.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND Saponins from Medicago species display several biological activities, among them apoptotic effects against plant cells have been evidenced. In contrast, their cytotoxic and antitumor activity against animal cells have not been studied in great details. OBJECTIVE To explore the cytotoxic

Genomics-based selection and functional characterization of triterpene glycosyltransferases from the model legume Medicago truncatula.

Numai utilizatorii înregistrați pot traduce articole

The biosynthesis of triterpene saponins is poorly characterized in spite of the importance of these glycosylated secondary metabolites for plant defense and animal health. The model legume Medicago truncatula synthesizes more than 30 different saponins based on at least five triterpene aglycones;
