introduction : in the recent years, due to the wide spread of resistant bacteria on one side and several different reports about the side effects of chemical drugs on the other side, vast researches on the medicinal plants have been started. in this study, antimicrobial effect of total extract of tribulus terrestris l . and its fraction containing benzoxazine derivative (terresoxazine) was stud...

This paper described the extraction procedure and determination method for the total flavonoids in ethanol extract from the leaves of Abutilon theophrasti Medic., and evaluated antibacterial and antioxidant activity. Maximum extraction yield was achieved using 60% ethanol, 1 : 30 (g/mL) of a ratio of material to solvent, 20 min of extraction time, 40 kHz of ultrasonic frequency, 100 W of ultras...

The investigation was conducted with methanolic extract of Murraya koenigii L for its anti bacterial, phytochemical screening and antioxidant capacities. Antibacterial activity of the extract was evaluated against various Grampositive and Gram-negative bacteria using agar well diffusion technique. For phytocehmical screening such as flavonoids. alkaloids, resins, glycosides, tannins, saponins, ...

abstract introduction: medicinal plants belong to lamiaceae family are potential sources of new drugs to improve the treatment of diseases which its treatment is linked to anti-oxidative agents. in this paper, antioxidant potentials of some lamiaceae species have been evaluated by two methods. methods: phosphomolybdate assay for total antioxidant capacity and ferric reducing antioxidant potenti...

The different solvent extracts of the leaves of Plectranthus amboinicus were evaluated for their antioxidant and antibacterial properties. The ethyl acetate extract of the leaves which had the highest polyphenolic content showed an appreciable DPPH radical scavenging activity as well as total antioxidant capacity as compared with extracts obtained using hexane, acetone, methanol, hydroalcohol a...

The ethanol crude extracts (ECE) and their subfractions from Zanthoxylum bungeanum leaves were prepared and their phytochemical profiles and antioxidant and antimicrobial activities were investigated. Moreover, the effective HPLC procedure for simultaneous quantification of twelve compounds in Z. bungeanum leaves was established. The correlation between the phytochemicals and antioxidant activi...

this study was carried out to evaluate the antimicrobial and antioxidant effectiveness of methanolic extract and different fractions (n-butanol, ethyl acetate, chloroform and n-hexane) of c.intybus seeds. the antimicrobial activity was determined by the disc diffusion method and minimum inhibitory concentration (mic) against a panel of microorganisms (four bacterial strains, i.e. p. multocida, ...

Chemical evaluation of the semi-purified fraction from the seeds of guaraná, Paullinia cupana H.B.K. var. sorbilis (Mart.) Ducke, yielded the following compounds: caffeine, catechin, epicatechin, ent-epicatechin, and procyanidins B1, B2, B3, B4, A2, and C1. Measurement of the antioxidant activity by reduction of the DPPH radical confirmed the anti-radical properties of the aqueous (AqE) and cru...

In this study, antioxidant and antibacterial activities of various solvent extracts (methanol, ethanol, acetone and petroleum benzine) obtained from bulbs and leaves of Allium deciduum subsp. deciduum and subsp. retrorsum were investigated. Antioxidant activity of the extracts was determined by DPPH radical scavenging and β-carotene/linoleic acid assays. In addition, total phenolic contents in ...

Hedyotis capitellata has widely used in traditional medicine for treatment of toxication, inflammation, diuretic, stomachache. H. capitellata has been showed to have antioxidant, anti-inflammatory and antibacterial effects. In this study we presented the acute and chronic anti-inflammatory and anticancer activities on HeLa, MCF7 and N87 cells line of H. capitellata. Our data showed that H. capi...
