Astragalus (Fabaceae), the largest genus of plants in the world with an estimated 3270 species, is known for large numbers of rare endemic species. An inventory of patterns of climatic, topographic, and edaphic diversity of Astragalus taxa in California (98 native species and 144 named taxa) provides a means to understand the occurrence of rarity in relation to climatic equitability and regiona...

BACKGROUND Herb-drug interactions (HDIs) resulting from concomitant use of herbal products with clinical drugs may cause adverse reactions. Organic anion transporter 1 (OAT1) and 3 (OAT3) are highly expressed in the kidney and play a key role in the renal elimination of substrate drugs. So far, little is known about the herbal extracts that could modulate OAT1 and OAT3 activities. METHODS HEK...

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. • ...
