Abstract Objectives We and others have shown that Aspilia pluriseta is associated with various biological activities. However, there a lack of information on its cytotoxicity. This has created an gap about the safety A. extracts. As extension to our recent publication antimicrobial activity phytochemical characterization root extracts, here we report cytotoxicity tested solvent fractions. evalu...

Knowledge of the mechanistic basis of differential aluminum (Al) tolerance depends, in part, on an improved ability to quantify Al located in the apoplastic and symplastic compartments of the root apex. Using root tips excised from seedlings of an Al-tolerant wheat cultivar (Triticum aestivum L. cv Yecora Rojo) grown in Al solutions for 2 d, we established an operationally defined apoplastic Al...

The objective of this present study was to explore the initial establishment of metabolically active bacteria and subsequent evolution in four fractions: rumen solid-phase (RS), liquid-phase (RL), protozoa-associated (RP), and epithelium-associated (RE) through early weaning and supplementing rhubarb root powder in 7 different age groups (1, 10, 20, 38, 41, 50, and 60 d) during rumen developmen...

This study was carried out to evaluate the antimicrobial activity of methanolic extract and different fractions (nbutanol, ethyl acetate, chloroform and n-hexane) of Glycyrrhiza glabra root. The antimicrobial activity was determined by the disc diffusion method and minimum inhibitory concentration (MIC) against a panel of microorganisms (four bacterial strains, i.e P. multocida, E. coli, B. sub...

Engineering drought -resistant crop plants is a critically important objective. Overexpression of the vacuolar H(+)-pyrophosphatase (H(+)-PPase) AVP1 in the model plant Arabidopsis thaliana results in enhanced performance under soil water deficits. Recent work demonstrates that AVP1 plays an important role in root development through the facilitation of auxin fluxes. With the objective of impro...

Biochemical changes occurred in roots of bur marigold and grapevine infected with Longidorus africanus. Phenols of infected root tips differed quantitatively from those of healthy root tips (optical density of 0.68 and 0.32, respectively). Column chromatography of the phenol extracts resulted in more fractions in the infected than in the healthy root extract. Of the enzymes involved in phenol m...

The study investigated the phytochemical and in-vitro antioxidants potential of Aristolochia bracteolata root extracts. Qualitative quantitative analysis plant extract fractions were carried out. total antioxidant free radical scavenging activity measured by 1, 1-diphenyl-2-picryl-hydrazyl, FRAP TBARS methods. Results obtained showed that saponins (10.10 ± 0.05d) as well found to be significant...

deleanu, frei, and hilton have developed the notion of generalized adams completion in a categorical context. in this paper, we have obtained the postnikov-like approximation of a module, with the help of a suitable set of morphisms.

The crude methanol extracts and fractions of the root and stem barks of Dillenia serrata Thunb. showed 64% to 73% inhibition on the production of prostaglandin E2 (PGE2) in lipopolysaccharide-induced human whole blood using a radioimmunoassay technique. Three triterpenoids isolated from the root bark of the plant, koetjapic (1), 3-oxoolean-12-en-30-oic (2), and betulinic (3) acids, exhibited si...
