Cytotoxicity assays using cell cultures may be an alternative to assess biological toxicity of plant extracts with potential phytotherapeutic properties. This study compared three methods to prepare culture media for the exposure of Vero cells to plant extracts. Leaves of Glandularia selloi (Spreng.) Tronc. were used to prepare culture medium with aqueous extract, extract in culture medium and ...

A method for the analysis of perchlorate in plants was developed, based on dry weight, and applied to the analysis of plant organs, foodstuffs, and plant products. The method reduced greatly the ionic interferences in water extracts of plant materials. The high background conductivity, due to the plant matrix, was reduced sufficiently to allow quantitation of perchlorate with little or no matri...

The present study investigates the qualitative and quantitative analysis of the major bioactive constituents of medicinally important plant Taraxacum officinale in its aqueous and methanol extract of root, stem and flower. Saponins, flavonoids, alkaloids, phenols were highly concentrated in the stem, root and flower, with the higher concentration of flavonoids in the flower extracts. Phenols an...

The whole plant of Jussiaea suffruticosa Linn. Has been widely used in traditional medicine of India. Important bioactive molecules of the plant extract have been explored with modern phytochemical approaches and reported to consist of betulinic acid, quercetin and β- sitosterol. Furthermore, the experimental data obtained from rational clinical studies indicated that the methanol extract of th...

Spilanthus acemella Murr. also known as toothache plant is investigated for its preliminary phytochemical analysis and molluscicidal activity. The water extract found maximum extractive value (3.730%) than other solvents used. All the tested metabolites were qualitatively present in ethanolic extract and aqueous extract. Different concentrations of plant parts (root stem, leaf) were used for mo...

ArisaemajacquemontiiBlume (Araceae) is reputed for its physiological properties in the folk medicine system and used in Chinese herbal medicine as anti-convulsant. Methanolic extracts of roots and fruits, the chloroform extracts of roots and shoots of ArisaemajacquemontiiBlume were investigated for immunomodulatory,antileishmanialand phytotixic activities. Immunomodulatory activitywas investiga...

The aim of the present study was to evaluate the anxiolytic effects of hydroalcoholic extract (HE) of Nepeta persica Boiss. (Lamiaceae) on the elevated plus-maze (EPM) model of anxiety. The extract of arial parts of the plant was administered intraperitoneally to male NMRI mice, at various doses, 30 min before behavioural evaluation. The HE extract of N. persica at the dose of 50 mg kg(-1) sign...

in this research psedomonas fluorescens as a probiotic, sodium chloride, plant extract (terminalia catappa), malachite green and formalin as antifungal agents were used daily for 19 days on rainbow trout fertilized eggs in order to compare their survival with untreated fertilized eggs in control group. results showed that the percent of live eggs (eyed) after 19 days treatment with p. fluoresce...
