Astragalus hamosus and corniculatus were examined for the presence of flavoalkaloids, acylated highly glycosylated flavonoids. Non-purified extracts overground parts species subjected to ultra-high performance liquid chromatography – high resolution electrospray ionisation mass spectrometry (UHPLC-HRESIMS) analysis results compared authentic reference substances. A flavoalkaloid kaempferol was ...

The phylogeny of symbiotic genes of Astragalus glycyphyllos L. (liquorice milkvetch) nodule isolates was studied by comparative sequence analysis of nodA, nodC, nodH and nifH loci. In all these genes phylograms, liquorice milkvetch rhizobia (closely related to bacteria of three species, i.e. Mesorhizobium amorphae, Mesorhizobium septentrionale and Mesorhizobium ciceri) formed one clearly separa...

Seed storage is the final stage of technological process its production, purpose which to ensure preservation seed quality from collection use. At same time, loss seeds in sowing conditions can cause significant losses both direct subjects production medicinal crops and producers raw materials. questions regarding terms sickle-leaved astragalus (Astragalus falcatus Lam.) rates their during rema...

The antioxidant effect of aqueous-ethanolic extract from Astragalus glycyphylloides (Fabaceae), and its protection against carbon tetrachloride-induced hepatotoxicity were investigated in male Wistar rats. For seven consequent days the animals were treated orally with A. glycyphylloides extract (EAG) (100 mg/kg). Two hours after the last administration the animals were charged with carbon tetra...

We investigated the effects of Astragalus polysaccharide (APS) on palmitate-induced insulin resistance in C2C12 skeletal muscle myotubes. Palmitate-reduced glucose uptake was restored by APS. APS prevented palmitate-induced C2C12 myotubes from impaired insulin signaling by inhibiting Ser307 phosphorylation of insulin receptor substrate-1 (IRS-1) and increasing Ser473 phosphorylation of Akt. Mor...

Chromosome number and karyotype of Astragalus stereocalyx Bornm. (Milk-vetch) in the section Stereocalyx Bornm. distributing naturally in Turkey were analyzed in detail. This species is endemic to Turkey and growing in Eskişehir and Konya provinces. Squash preparation method was used for chromosome study in this species. The somatic chromosome number was determined as 2n = 16 in A. stereocalyx....

Some Chinese herbs are anti-thrombolysis, and anti-inflammatory, improves brain RNA content, promotes brain protein synthesis, enhances dopamine function, regulates brain hormones, and improves microcirculation in central nervous system that might improve, repair and rehabilitation from the stroke and brain injury. Specific Chinese herbs and their components, such as Acanthopanax, Angelica, cou...

Astragalus bibullatus (Fabaceae) is an endangered plant species endemic to limestone cedar glades in Tennessee. Data from 134 amplified fragment length polymorphism (AFLP) fragments indicate that populations of this species are genetically very similar, with genetic identity values ranging from 0.976 to 0.991. Approximately 10% of the species' total genetic variation is due to differences among...
