In this study, distribution of Calcium oxalate (CaOx) crystal types within generative organs of Astragalus hamosus L. and Astragalus glycyphyllos L. and crystal types of them were examined using light microscopy (LM). During cytoembryological studies on A. glycyphyllos, CaOx crystals have been observed in generative organs. Prismatic and druse type crystals were determined in different regions ...

Astragalus L., is one of the largest genuses of flowering plants in the Leguminosae family. Roots of A. membranaceus Bge. var. mongholicus (Bge.) Hsiao, A. membranaceus (Fisch.) Bge. and its processed products are listed in the China Pharmacopeia for "qi deficiency" syndrome treatment. However, more and more researches on other species of Astragalus have been conducted recently. We summarize th...

Astragalus L. is a perennial herbaceous genus belonging to the family Fabaceae. Chromosome morphology was defined for the first time in four species of Astragalus namely; A. antalyensis A.Duran & Podlech, A. nezaketae A.Duran & Aytaç, A. cariensis Boiss. & A. schizopterus Boiss. All species contained diploid chromosome numbers of 2n = 16. However, polyploid cells (4x = 32) were also observed in...

This paper shows the changes of the volatile compounds from four Astragalus species at three phenological stages: leaf development, flowering and fructification, which might be connected with the plant defense. After GC/MS analyses of Astragalus glycyphyllos L., A. hamosus L., A. cicer L. and A. spruneri Boiss., different groups of volatile compounds were found: hydrocarbons, alcohols, aldehyde...

BACKGROUND Astragalus was broadly used for treating heart failure (HF) and arrhythmias in East Asia for thousands of years. Astragalus granule (AG), extracted from Astragalus, shows beneficial effect on the treatment of HF in clinical research. We hypothesized that administration of AG prevents the remodeling of L-type Ca2+ current (ICa-L) in HF mice by the downregulation of Ca2+/calmodulin-dep...

Some species hyperaccumulate selenium (Se) upwards of 0.1% of dry weight. This study addressed whether Se hyperaccumulators also accumulate and tolerate more molybdenum (Mo). A field survey revealed on average 2-fold higher Mo levels in three hyperaccumulator Astragali compared to three nonaccumulator Astragali, which were not significantly different. Next, a controlled study was performed wher...

Many foods and food components boost the immune system, but little data are available regarding the mechanisms by which they do. Bacterial strains have disparate effects in stimulating the immune system. In dendritic cells, the gram-negative bacteria Escherichia coli upregulates proinflammatory cytokines, whereas gram-positive Lactobacillus acidophilus induces a robust interferon (IFN)-β respon...

Astragalus L., is one of the largest genus of flowering plants in the Leguminosae family. The aim of this study was to review anti-carcinoma activities of this valuable herb. This review article was carried out by searching studies in PubMed, Medline, Web of Science, and Iran Medex databases .The initial search strategy identified about 128 references. In this study, 113 studies was accepted fo...

Abstract. Microclonal propagation of rare plant species solves the problem biodiversity conservation, because received explants can be introduced into natural conditions to maintain stability communities. The purpose research was obtain in vitro cultures plants from Fabaceae family: Astragalus gorodkovii and gorczakovskii. Materials methods: seeds were selected population Komi Republic 2004. Se...
