As a result of a taxonomic and phylogenetic revision of Astragalus section Hymenostegis we identified a new species of Astragalus from northwestern Iran, namely A. remotispicatus spec. nov., which is described and illustrated here. It is morphologically similar to A. karl-heinzii in possessing a lax inflorescence. Phylogenetic inference of the nuclear ribosomal DNA internal transcribed spacer (...

Abstract Five flavonol glycosides, including a new glutaryl-conjugated compound, were isolated from methanolic extract of the endemic Balkan species Astragalus thracicus Griseb. Based on NMR and MS spectra, one compound was identified as kaempferol 3-O-[?-glucopyranosyl-(1?4)-?-rhamnopyranosyl-(1?6)-(2-3-hydroxy-3-methylgutaroyl)-?-galactopyranoside)] (1). The other compounds, all known, maurit...

Determining the Potential Habitat of Astragalus verus using CART Regression Decision Tree Algorithm (Case Study: West Isfahan Province)

The effects of supplemental dietary creatine and a botanical extract consisting of ginseng and astragalus were evaluated in 44 adults aged 55-84 years participating in a 12-week strength-training program. Participants consumed creatine only (Cr), creatine plus botanical extract (CrBE), or placebo (PL), and performed bench press, lat pull down, biceps curl, leg press, knee extension, and knee fl...

UNLABELLED PREMISE OF STUDY A survey of the root-nodule symbiosis in Astragalus and its interaction with selenium (Se) has not been conducted before. Such studies can provide insight into how edaphic conditions modify symbiotic interactions and influence partner coevolution. In this paper plant-organ Se concentration ([Se]) was investigated to assess potential Se exposure to endophytes. • ...

The high degree of degradation and the low angiogenic capabilities of temporary tissue substitutes still represent a major challenge in the field of tissue engineering. In an attempt to meet some of these challenges we covalently incorporated Astragalus polysaccharides, a plant extract with angiogenic properties, into collagen matrices. This contribution aims at developing a three-dimensional s...
