Introduction: In this study, Antibacterial and antioxidant activities of the essential oil and methanolic extract of the endemic plant, Zataria multiflora Boiss. have been studied. Method: The antioxidant potential of the samples was evaluated using two separate methods of inhibition of free radical 2,2-diphenyl-1-picrylhydrazyl (DPPH) and ammonium thiocyanate systems. Antibacterial activity wa...

Column chromatography of the dichloromethane fraction from an aqueous methanolic extract of fruit peel of Citrus pyriformis Hassk. (Rutaceae) resulted in the isolation of seven compounds including one coumarin (citropten), two limonoids (limonin and deacetylnomilin), and four sterols (stigmasterol, ergosterol, sitosteryl-3-beta-D-glucoside, and sitosteryl-6'-O-acyl-3-beta-D-glucoside). From the...

The extracts of the dried leaves of Anacardium occidentale  were screened for anti-inflammatory activity using carrageenan induced rat paw edema model. The petroleum ether and chloroform extract and acetone soluble fraction of methanolic extract showed 57.14%, 47.61% and 61.90% inhibition of paw edema respectively. Acetone soluble extract showed better activity than petroleum either and chlorof...

BACKGROUND Urtica dioica, Taraxacum officinale, Calea integrifolia and Caesalpinia pulcherrima are widely used all over the world for treatment of different illnesses. In Mexico, these plants are traditionally used to alleviate or counteract rheumatism and inflammatory muscle diseases. In the present study we evaluated the activity of aqueous and methanolic extracts of these four plants, on the...

        The crude methanolic extract of the seeds of Celastrus paniculatus along with its organic soluble fractions were tested for their possible antioxidant and anti-alzheirmer (AD) activity. The extracts showed prominent DPPH free radical scavenging activity, inhibiting activity of authentic peroxynitrite (ONOO-) and inhibition of total reactive oxygen species (ROS) generation. In D...

Irvingia malayana has been utilized for traditional medicine in West Kalimantan, Indonesia.The aim of this research is to detect cytotoxic activity of extract of Irvingia malayana. The extraction with methanol and partition by variated eluen polarity. This extraction produced methanol extract, n-hexane fraction, methylene chloride fraction, ethylacetate fraction and methanol fraction. Cytotoxic...

This study aimed to determine biological activity and phytochemical study of Scutellaria platystegia (family Labiatae). Methanolic (MeOH) extract of aerial parts of S. platystegia and SPE fractions of methanolic extract (specially 20% and 40% methanolic fractions), growing in East-Azarbaijan province of Iran were found to have radical scavenging activity by DPPH (2, 2-diphenyl -1- pycryl hydraz...

The main objective of this experiment was to investigate the antiinflammatory activity of Citrullus lanatus methanol extract (ME) and its fractions in adult male albino rats. Citrullus lanatus has been traditionally used for various disease and disorders. The phytochemical evaluation of methanolic seeds extract showed the presence of carbohydrate, alkaloids, steroids, saponins, flavonoids, tann...

Chemical fractionation of the methanolic extract of leaves of Leiothrix spiralis Ruhland afforded the flavonoids luteolin-6-C-β-D-glucopyranoside (1), 7-methoxyluteolin-6-C-β-D-glucopyranoside (2), 7-methoxyluteolin-8-C-β-D-glucopyranoside (3), 4'-methoxyluteolin-6-C-β-D-glucopyranoside (4), and 6-hydroxy-7-methoxyluteolin (5), and the xanthones 8-carboxymethyl-1,5,6-trihydroxy-3-methoxyxanthon...
