Purpose: To determine, in Sprague Dawley rats, the toxicity profile of the methanol extract of Mentha spicata, a plant used in folklore medicine for the treatment of various forms of pain. Methods: The plant extract, at concentrations ranging from 100 0.07 mg/ml, was used to determine the median lethal concentration (LC50) based on brine shrimp lethality assay. Artificial sea water served as co...

Our recent study has revealed six plant extracts that slow yeast chronological aging more efficiently than any chemical compound yet described. The rate of aging in yeast is controlled by an evolutionarily conserved network of integrated signaling pathways and protein kinases. Here, we assessed how single-gene-deletion mutations eliminating each of these pathways and kinases affect the aging-de...

Investigated six plant extracts viz.,, kaner leaf extract (Nerium indicum), khejri leaf extract (Prosopis cineraria), neem leaf extract (Azadirachta indica), safeda leaf extract (Eucalyptus globulus), tomato leaf extract (Lycopersicum esculentum) and mustard seed extract (Brassica compestris) and four plant powders viz.,, black pepper powder (Piper nigrum), garlic clove powder (Allium sativum),...

BACKGROUND Euphorbia hirta possesses antibacterial, anti-inflammatory, galactogenic, antidiarrheal, antioxidant, hypoglycemic, antiasthmatic, antiamebic, antifungal, and antimalarial activities. OBJECTIVE The overall objective of the current study was the investigation of the whole plant extract of E. hirta and flavonoids from E. hirta on gastroesophageal reflux disease (GERD) in rats. MATE...

peperomia pellucida leaf extract was characterized for its anticancer, antimicrobial, antioxidant activities, and chemical compositions. anticancer activity of p. pellucida leaf extract was determined through colorimetric mtt (tetrazolium) assay against human breast adenocarcinoma (mcf-7) cell line and the antimicrobial property of the plant extract was revealed by using two-fold broth micro-di...

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...
