Curcuma lithophila and C. rufostriata, two new species from subgen. Hitcheniopsis, are described illustrated. They compared with their morphologically closest species, rhabdota, papilionacea sparganiifolia. Notes on distribution, ecology, etymology, uses IUCN provisional assessments provided. Further notes the distribution of recently an improved conservation assessment reported additional coll...

BACKGROUND Chinese herbal injections (CHIs) have been proven beneficial to patients with gastric cancer for improving clinical efficacy and relieving adverse reactions (ADRs) of chemotherapy. A network meta-analysis (NMA) was conducted in this study to assess the comparative efficacy and safety of CHIs combined with FOLFOX regimen for treating gastric cancer. RESULTS A total of 2316 records w...

A checklist of Oppiidae sampled at Golden Gate Highlands National Park in central South Africa is provided. Twelve genera and 17 species were recorded of which one species, Arcoppia fenestralis, is recorded from South Africa for the first time. One new subgenus and six new species were identified and are described. The new species are Brachioppia louwi sp. nov., Brachioppiella (B.) dawidi sp. n...

OBJECTIVE To evaluate the antioxidant activities of different chemical constituents from Astragalus mongholicus Bunge and their protection against xanthine (XA)/xanthine oxidase (XO)-induced toxicity in PC12 cells. METHODS The compounds of Astragalus mongholicus Bunge were isolated by chromatography and the structures were elucidated on the basis of spectral data interpretation. Their antioxi...

Astragalus roots from Astragalus membranaceus Bunge or Astragalus membranaceus var. mongholicus (Bunge) Hsiao are among the most popular traditional medicinal plants due to their diverse therapeutic uses based on their tonic, antinephritic, immunostimulant, hepatoprotectant, diuretic, antidiabetic, analgesic, expectorant and sedative properties. Currently, the herb is produced or cultivated in ...

Phylogenetic analyses of large data sets pose special challenges, including the apparent tendency for the bootstrap support for a clade to decline with increased taxon sampling of that clade. We document this decline in data sets with increasing numbers of taxa in Astragalus, the most species-rich angiosperm genus. Support for one subclade, Neo-Astragalus, declined monotonically with increased ...

melanin pigment plays a critical role in camouflage and   protection against harmful effects of solar radiation. melanogenesis is under   complex regulatory control by multiple agents. tyrosinase is a   multifunctional, which catalyzes the first two steps in mammalian   melanogenesis. in this study, inhibitory effects of astragalus fasciculifolius   and astragalus gypsicolus on diphenolase acti...

Only a few species of the large Astragalus genus, widely used for medicinal purposes, have been thoroughly studied for phytochemical composition. The aim of our research was to investigate the rarely studied species A. glycyphyllos L. and A. cicer L. for the distribution of mineral elements and phytochemicals in whole plants at two growth stages and in morphological fractions. We also investiga...
