Antennaria dioica (L.) Gaertn. and Helichrysum arenarium (L.) Moench. are two species of the Asteraceae family, known in Romanian traditional medicine for their diuretic, choleretic, and anti-inflammatory properties. The aim of the present study was to evaluate the phenolic and sterolic composition of flowers from the two species and to assess their antioxidant, antibacterial and antifungal pro...
The ethanolic extracts of aerial shoots of Mollugo cerviana and its leaf derived callus were tested for antimicrobial activity using the filter paper disk assay method. Both the extracts showed antibacterial activity against Bacillus subtilis and Escherichia Coli. The antifungal activity of the extracts against Aspergillus niger and Aspergillus flavus was nil or negligible.
The study was undertaken to assess the dosage-mortality ratio and toxic effects of Piper guineense fruit extracts on the adults of Biomphalaria pfeifferi, the snail intermediate host of Schistosoma mansoni, which causes intestinal schistosomiasis. The result showed significant toxic effects with crude ethanol and hot water fruits extracts. The estimated lethal dose concentration by arithmetic m...
ABSTRACT Introduction Leaves of Tephrosia purpurea Linn (sarpankh), belonging to the family Leguminosae being used for the treatment of jaundice and claimed to be effective in many other diseases. The present research work was under taken to investigate the in-vitro antioxidant activity of aqueous and ethanolic extracts. Method The therapeutic effects of tannins and flavonoids can be largely at...
A method for the separation and quantification of three flavonoids and one isocoumarin by reverse-phase high performance liquid chromatography (HPLC) has been developed and validated. Four constituents present in a crude ethanolic extract of the flowers of Coryloposis coreana Uyeki, were analyzed. Bergenin, quercetin, quercitrin and isosalipurposide were used as calibration standards. In the pr...
Background. In this study antimicrobial effect of ethanolic and aqueous extracts of Juglans regia bark in Iran was evaluated on four different oral bacteria, Streptococcus mutans, Streptococcus salivarius, Streptococcus sanguis, and Staphylococcus aureus. Methods. Aqueous and ethanol extracts of Juglans regia bark were prepared by using disk diffusion technique and Minimal Inhibitory Concentrat...
Ethanolic extract of Naringi crenulata or liminonia crenulata leaves was investigated for Phytochemical and Antimicrobial activities. The macroscopic characteristics of leaves, physical constant values, extractive values, behavior on treatment with different chemical reagents of the powdered leaves. Naringi crenulata were studied to fix some pharmacognostical parameters and preliminary phytoche...
The antibacterial activity of the ethanolic and methanolic extracts from the mossEntodon nepalensis Mizush. was evaluated against three bacterial species. The antibacterial activity was assessed by well diffusion method. The ethanolic extract of plant showed a stronger effect than the methanolic extract. The maximum antagonistic effect showed against tested Escherichia coli followed by Salmonel...
The antiproliferative and antioxidant potential of Cymbopogon citratus (Lemon grass) extracts were investigated. The extracts were isolated by solvent maceration method and thereafter subjected to antiproliferative activity test on five different cancer cells: human colon carcinoma (HCT-116), breast carcinoma (MCF-7 and MDA-MB 231), ovarian carcinoma (SKOV-3 and COAV), and a normal liver cell l...
According to biologically active compounds and traditional use of the Satureja bachtiarica, seem that this plant has significant antimicrobial effects. In this study antimicrobial effect of extracts evaluated by two methods, “Collins method” and “disk agar diffusion method” on Escherichia coli PTCC 1330 and Staphylococcus aureus PTCC 1337 microorganisms. The minimum inhibitory concentration (MI...
