Echinops spinosus, belonging to Asteraceae family, is used in folk medicine as an abortifacient and diuretic for blood circulation, diabetes, stomach pain, indigestion spasmolytic problems. The objective of this work the study acute toxicity, content phenolic compounds (polyphenols, flavonoids tannins), antioxidant activity (DPPH, ABTS, FRAP, H2O2 xanthine oxidase) antidiabetic (?-amylase, ?- g...

Effects of red (600 to 680 nanometers) and far red (700 to 760 nanometers) irradiances on Amaranthus retroflexus L. seeds indicate that synthesis of phytochrome in the red-absorbing form takes place in water-imbibed nongerminating seeds at 35 C. After 96 hours in darkness, conversion of about 0.10% phytochrome to the far red-absorbing form induces 50% germination. Continuous far red radiation a...

Laelaps neacomydis n. sp. is described from the pelage of the rodent Neacomys spinosus collected in Bolivia. Collection records from northern Brazil, southeastern Peru, and central Bolivia indicate its wide distribution across Amazonas associated with rodents of the genus Neacomys. The formal taxonomic description and illustrations are derived from the adults (female and male). Two larger speci...

BACKGROUND AND AIMS Cress-seed (Lepidium sativum) exudate exerts an allelochemical effect, promoting excessive hypocotyl elongation and inhibiting root growth in neighbouring Amaranthus caudatus seedlings. We investigated acidic disaccharides present in cress-seed exudate, testing the proposal that the allelochemical is an oligosaccharin-lepidimoic acid (LMA; 4-deoxy-β-l-threo-hex-4-enopyranuro...

Nine species of Alysson Panzer 1806 are recorded from Russia and adjacent territories. The new synonymy is proposed for Alysson pertheesi Gorski 1852 =A. fuscatus var. jaroslavensis Kokujev 1906, =A. harbinensis Tsuneki 1967; Pompilus spinosus (Panzer 1801) =Alysson katkovi Kokujev 1906. The number of valid species-group taxa in the genus Alysson is reduced to 39 species. An original key to the...

Phytoextraction field experiments were conducted on soil contaminated with 0.39 to 8.7 Bq/g of 137Cs to determine the capacity of five plant species to accumulate 137Cs and the effects of three soil treatments on uptake. The plants tested were redroot pigweed (Amaranthus retroflexus L. var. aureus); a mixture of redroot pigweed and spreading pigweed (A. graecizans L.); purple amaranth (A. crute...

This study examined the levels of heavy metals in soil, water, and vegetables (amaranthus, hibiscussabdariffa, allium cepa leaves) around industrial area Bauchi, Northeastern Nigeria. The composite samples were collected determine level (Mn, Zn, Cd, Pb, As) using Atomic Absorption Spectrophotometer (AAS). decreased order Mn > Zn Pb Cd respectively. Among vegetables, amaranthus had highest fo...
