We assessed the bioactivity of G. kola seeds on Streptococcus pyogenes, Staphylococcus aureus, Plesiomonas shigelloides and Salmonella typhimurium. The crude ethyl acetate, ethanol, methanol, acetone and aqueous extracts were screened by the agar-well diffusion method and their activities were further determined by Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (M...

As a widely used food preservative, methyl paraben was experimentally evidenced with serious hormone-like adverse effect. Herein, high performance thin-layer chromatography platformed bioluminescent bioautography and image analysis for the selective quantification confirmation of proposed validated in vinegar coconut juice. First, detectability to analyte on different layer materials estimated,...

members of the genus bacillus are among the most promising candidates for biological control of plant pathogenic bacteria. in this study, cell free supernatants of three strains b. subtilis utb96, b. subtilis utb1 and b. subtilis utb70 against aspergillus flavus r5 were investigated using dual culture assay. strain b. subtilis utb96 showed the highest inhibition effect. thin lyer chromatography...

The genus Echinops belonging to the Asteraceae family comprises 130 species. The dried leaves and seeds of Echinops orientalis Trauv. were extracted separately with methanol. Apigenin-7-O-(6"-trans-pcoumaroyl--D-glucopyranoside 1, and Apigenin-7-O--D glucoside 2 were isolated from leaves and 1methoxycarbonylindole 3 and beta-sitositerol 4 were isolated from seeds. The compounds were isolated ...

Decoction of roots of the Amazonian palm açaí (Euterpe precatoria Mart.) is widely used by Brazilian and Peruvian people as an anti-inflammatory, to heal kidney and liver diseases and against snake bites. In this study, the antioxidant activity of extracts and flavonoids (quercetin, catechin, epicatechin, rutin and astilbin) isolated from roots and leaf stalks of E. precatoria was investigated ...

The essential oils of branchlets and fruits of Juniperus excelsa subsp. excelsa and Juniperus excelsa subsp. polycarpos were examined for their antioxidant activity. The compositions of the essential oils were studied by GC and GC-MS. To evaluation the antioxidants activity of the volatile oils, pure components and positive controls at different concentrations, thin-layer chromatography (TLC) s...

Alongside with antioxidant, pro-oxidant activity is also observed in phytochemical compounds. In the study, Ficus odorata, an endemic medicinal plant in the Philippines, was screened for the potential medical application of its pro-oxidant activity. Phytochemical screening revealed the presence of terpenes, glycosides and phenolic acids. The crude extract was found to contain low gallic acid an...

Kaempferia parviflora Wall. ex Baker is a medicinal plant found in the upper Northeastern regions of Thailand, which belongs to Zingiberaceae family. The present study aims to investigate the standardization parameters, to analyze chemical constituents of volatile oil by gas chromatography-mass spectrometry, and to determine the content of 5,7-dimethoxyflavone in K. parviflora rhizomes by thin-...

Sponge-associated bacteria can produce bioactive compounds similar to the host. Here, investigation of antioxidant properties yellow-red pigment produced by sponge-associated bacterium AGS112 was conducted using in vitro and vivo analysis. The 16S rRNA gene sequence showed has closest similarity with Bacillus haikouensis C-89 (99%). crude extract contained both phenolic flavonoid. peaks occurre...

BACKGROUND Diseases caused by bacteria remain a major challenge globally and particularly in sub-Saharan Africa. The plants used in this study have been used in South Africa to treat helminth infections in livestock and humans. In a previous study we found a correlation between antifungal and anthelmintic activity in some cases. In this study we examined other potential uses of these thirteen p...
