BACKGROUND Tropaeolum pentaphyllum Lam. tubers (Tropaeolaceae) are known and used as a condiment and for the treatment of skin infections in Southern Brazil. However, its activity and composition has not yet been investigated. Thus, different extracts and the essential oil from the tubers were tested against a range of microorganisms. The most active extracts were submitted to chromatographic a...

A pot experiment was conducted to determine the effect of compost and bio-fertilizers on the growth, yield and oil constituents of marjoram (Majorana hortensis L.). Forty five days old seedling were transplanted in soil treated with 15 and 30% aqueous extracts of compost and/or biofertilizers (mixture of Azospirillum brasilienses, Azotobacter chroococcum, Bacillus polymyxa & B. circulans) in ad...

The first aim of this study is to evaluate the in vitro antimicrobial activity of the essential oil and two extracts of Saharan myrtle: Myrtus nivellei Batt & Trab. For this purpose, paper disc-diffusion method and micro-dilution test were used. As far as the antimicrobial activity is concerned the essential oil exhibited higher ones against S. epidermidis (MIC=0.28mg/ml), S. typhi (MIC=0.56mg/...

Aim of the present investigation was to assess the in vitro efficacy of different plant extracts againsts fungi isolated from bovine mastitis cases. Twenty-six species of yeast, yeast like and moulds were isolated from 200 mastitic milk samples. The isolates were identified based on the staining, cultural and biochemical characteristics. Aqueous extracts of cinnamon leaf, lemon grass, clove, an...

Background: To study the anticancer activity of Plantago major, ethanolic, methanolic and acetonic extracts were assessed on HCT116, SW480 and HEK-293 as control. Methods: The cytotoxic activity, biocompatibility and toxicity tests were evaluated by MTT assay, hemolysis and Artemia salina - LD50 (on mice) tests, respectively. The analysis of essential oil compounds was performed by GC-MS analys...

Background and objectives: The genus Artemisia, an important member of the Asteraceae family, is mostly distributed in Europe, North America, Asia and South Africa, and represented in Iranian flora by 34 species. In the Iranian traditional medicine these plants were used as anthelmintic and anti-inflammatory. The presence of sesquiterpene lactones and germacranolides w...

Zhumeria majdae is a rare an endemic medicinal plantspecies grown wild in Iran. The hydro distilled essential aerial part oil of Z. majdae analysed by GC–MS. Thirty-one compounds representing 95.36% of the aerial part oil, respectively, were identified, of which linalool (48.14%), camphor (20.71%), limonene (4.83%), trans-linalool oxide (2.69%), 3-Octanone (2.34%), terpinene-4...

In the present work, a comprehensive study was made on the analysis of chemical composition of essential oil and antibacterial activity from the leaves of Ajuga bracteosa. The essential oil was extracted by Cleavenger type apparatus and analyzed by GC-MS. The main components present in the essential oil of leaves are Limonene, α-humulene, β-Myrcene, Elemol, Camphene, βCaryophellene, α-phellendr...

This research highlights the chemical composition, antioxidant and antibacterial activities of essential oils and various crude extracts (using methanol and methylene chloride) from Syzygium cumini leaves. Essential oils were analyzed by gas chromatography-mass spectrometry (GC-MS).The abundant constituents of the oils were: α-pinene (32.32%), β-pinene (12.44%), trans-caryophyllene (11.19%), 1,...
