Effects of n-butanol and water fractions from Pedicularis decora Franch on oxidative stress in mice induced by a single bout of swimming exercise
This study investigated the effect of water and n-butanol fractions from Pedicularis decoraFranch roots on oxidative stress induced by a single bout of swimming exercise. ICR mice were treated orally with water and n-butanol fractions for three weeks. Lipid peroxidation (LPO) levels, transaminases activities significantly decreased and superoxide dismutases (SOD), glutathione peroxidase (GPx)...

Abundant high-quality RNA from medicinal plants for molecular applications
Medicinal plants provide cure for several human and animal diseases. As a pre-requisite towards manipulating gene expression and engineering metabolites, efficient RNA isolation protocol from medicinal plants is needed. In the present study, four recent protocols of RNA isolation were compared based on the electrophoretic pattern as well as, the A260/A280 and A260/230 ratios of RNAs isolated from an important medicinal...

Down regulation of matrix metalloproteinases by spearmint extract in Wehi-164 cells
Tumor invasion and metastasis are the main causes of cancer death. Matrix metalloproteinases (MMPs) are endopeptidases which degredate the extracellular matrix proteins. MMPs have an important role in tumor progression and metastasis. Fibrosarcoma has been recognized as a highly metastatic cancer which its current therapeutic methods have not been very successful. Medicinal plants are widely used in treatment of...

Comparison of phenolic compounds content in indeciduous Quercus species
Indeciduous Quercus species have been used in Korean folk medicine, having effects on various diseases such as dysentery, diarrhea, hemorrhagia and dermatitis. In this study, five Quercus species were used for determination of phenolic compounds. In particular,phenolic compounds content in Quercus salicina Blume was compared between its leaf and shoot. Results indicated that the...

Preparative enrichment and separation of isofraxidin from Acanthopanax senticosus with HPD100C macroporous resin
Isofraxidin is known as the major pharmacological component in Acanthopanax senticosus. In the present study, in order to screen a suitable resin for the preparative separation and purification of isofraxidin, the adsorption and desorption properties of 26 widely used commercial macroporous resins were evaluated. The preliminary research results indicated that HPD100C...

Biological screening of Hedera nepalensis
The aim of the current work was to screen the crude methanolic extract (Cr. MeOH Ext.) and various fractions of Hedera nepalensis for antibacterial, antifungal, brine-shrimp lethality, phytotoxicity, heamagglutination, insecticidal and nitric oxide free radical scavenging assay. The results revealed that chloroform (CHCl3) fraction of the plant possess good antibacterial activity (60%)...

Antioxidative activity of taheebo (Tabebuia impetiginosa Martius ex DC.) extracts on the H2O2-induced NIH3T3 cells
The antioxidant activities of Tabebuia impetiginosa methanolic extract (TIME) were examined with its serial solvent extracts using hexane, chloroform and ethyl acetate against hydrogen peroxide (H2O2)-induced oxidative stress in NIH3T3 cells. The three serial extracts were selected for the study of regeneration on antioxidant enzyme activities because butanol and water extracts significantly affected cell...

Fatty acid composition, antioxidant and antibacterial activities of Pistacia lentiscus L. fruit oils
This study was performed on oil extracted from mature fruits of Pistacia lentiscus L. harvested from Northern and North Western Tunisia. Extraction was done by two methods: Traditional method practiced by women in forest areas and pressing method that was proposed to improve the yield and the quality of oil. Fatty acid composition was determined by gas chromatography-mass spectrometry (GC/MS). Oleic acid was...
