One new cycloartane-type saponin, 3-O-[β-D-xylopyranosyl-(1→2)-β-D-xylopyranosyl]-6-O-β-Dglucuronopyranosyl-3β,6α,16β,24(S),25-pentahydroxyxyxloartane (1) was isolated from the MeOH extract of whole plant parts of Astragalus erinaceus along with 5 known saponins (2-6), cyclodissectoside, cycloastragenol, 6-O-β-D-glucopyranosyl-3β,6α,16β,24(S),25-pentahydroxycycloartane, oleifolioside B and 3,6d...

PREMISE OF THE STUDY Juncus roemerianus (Juncaceae) is a foundational species and ecosystem engineer of salt marshes in the Gulf of Mexico. These ecosystems provide coastal flood attenuation, nurseries for important species, and other ecosystem services, but are experiencing significant decline. Nuclear microsatellite markers were developed for J. roemerianus to study genetic diversity and popu...

BACKGROUND Non-small-cell lung cancer (NSCLC) is a leading cause of death. Interventions to reduce mortality in patients with NSCLC represent a patient-important field of research. Little is known about interventions used outside the Western world for NSCLC. One intervention widely used in Asia is astragalus-based herbal preparations. METHODS We conducted a comprehensive systematic review of ...

Abstract Medicinal plants always are part of folk medicine and nowadays receiving worldwide attention for prophylaxis, management, treatment several diseases, as an alternative to chemical drugs. The current work provided a comprehensive overview analysis the Astragalus health relationship in literature. their therapeutic potential is thus instrumental understand bioactivity. Among these, flowe...

Radix Astragali, the root of Astragalus (A.) membranaceus, has been applied in a variety of diseases for a long time in Asian countries such as Korea and China. In addition, the aerial parts such as leaves and stems of A. membranaceus have received a great deal of attention. Recently, the polysaccharide fraction showing a potent immunomoduating activity was isolated from the aerial parts of A. ...

The content of total phenolics in roots, leaflets and seeds of a number of Astingulus species from Iran was examined. Phenolics content of the aqueous and methanolic extracts of the species were determined spectrophotometrically. Phenolics content depend on factors such as the species, geographical location of the plants and the organs. Moreover, the content of phenolics depends on the extracti...

The conservation of rare plant species hinges on our ability to identify the underlying mechanisms that limit rare plant populations. Theory on rarity suggests that both predispersal seed predation and competition can be important mechanisms influencing abundance and/or distribution of rare plant populations. Yet few studies have tested these interactions, and those that have evaluated each mec...
