Protein tyrosine kinase (PTK) as a novel target for some natural anti-cancer molecules extracted from plants
For the fact that protein tyrosine kinases (PTKs) are important components of signal transduction pathway, they also are involved in regulating cell growth, differentiation and oncogenesis. Therefore, protein tyrosine kinases represent a potential target for cancer treatment. Drugs known as protein tyrosine kinase (PTK) inhibitors play a key role in developing therapeutic strategies for cancer therapy and plants are...

In vitro antibacterial activity of seven plants used traditionally to treat wound myiasis in animals in Southern Africa
In the extreme situation of subsistence farming where insecticides and other veterinary medicines are either unavailable or unaffordable, the use of plants in the treatment of wound myiasis in livestock has been reported worldwide. However, the exact effect of these plants on myiatic wounds has not been established. This study was therefore undertaken to establish the biological activity of seven species of plants which...

Comparative study on different methods for Lonicera japonica Thunb. micropropagation and acclimatization
In this study, we reported the establishment of a simple protocol for the micropropagation and acclimatization of Lonicera japonica Thunb. Branches with dormant buds were collected from mature L. japonica and sprouted in a greenhouse. Tip and node segments were used as starting material for in vitro proliferation in woody plant medium (WPM). In the first assay in which explants from five...

Effect of water stress on essential oil yield and storage capability of Matricaria chamomilla L.
To evaluate the effect of water stress on yield and storage capability (essential oil percentage, yield and harvest index during five years storage period) of Matricaria chamomilla L., a field experiment was conducted in 2005. Water stress treatments of irrigation after 30, 60, 90 and 120 mm evaporation from pan class A, were arranged as randomized complete block design with six replications. The harvested...

Enhanced callus induction and high-efficiency plant regeneration in Tribulus terrestris L., an important medicinal plant
We described culture conditions for direct and indirect regeneration of Iranian Tribulus terrestris L. through epicotyl, hypocotyl and leaf explants. The explants were cultured on MS medium supplemented with different concentrations and combinations of auxin and cytokinin. The results indicated that the mean of callus induction was influenced by explant type and various phytohormones levels. The highest...

Chemical composition and antioxidant activity of Lippia species
Chemical composition of the hexanic fraction, antioxidant activity (DPPH assay) and total phenolic content (Folin-Ciocalteau assay) of aerial parts of sixteen Lippia species were determined. Hexanic fraction was analyzed by gas chromatography-mass spectrometry (GC-MS). The compounds β-myrcene, limonene, γ-terpinene, linalool, β-caryophyllene, germacrene D, α–copaene,...

Evaluation of biochemical, hematological and histopathological parameters of albino rats treated with Stemona aphylla Craib. extract
In order to measure the safety of Stemona aphylla Craib., an effective insecticidal plant, on mammals, the effects of the ethanolic extracts from the root of S. aphylla on blood biochemical, hematological and histopathological indices of albino rats have been evaluated. Male rats were given extracts orally at the doses of 300 and 500 mg/kg body weight/day for 45 consecutive days. These were compared...

Assessment of fluoride, chloride and sulfate contamination of herbal teas, and possible interference with the medicinal properties
Herbal teas are sold for medicinal purposes, as well as a beverage. Herbal teas may consist of many ingredients, mainly botanical ingredients, and therefore are susceptible to contamination from the environment and manufacturing processes, which can interfere with their medicinal purposes. This research investigated the contamination of herbal teas by fluoride, chloride and sulfate. The results demonstrated that none of...

Effects of Moringa oleifera methanolic leaf extract on the morbidity and mortality of chickens experimentally infected with Newcastle disease virus (Kudu 113) strain
Newcastle Disease (ND) is an important disease of poultry worldwide. Its economic impact is high because mortality may reach 100% in affected poultry farms. This study was aimed at evaluating the protective properties of crude methanolic extract of Moringa oleifera in chickens. Forty two-day old chicks were randomly divided into four groups: I, II, III and IV. Groups I and II were given daily oral...

Antioxidant and antimicrobial activities of Chowlai (Amaranthus viridis L.) leaf and seed extracts
The present study was conducted to evaluate the phenolics, antioxidant and antimicrobial activities of leaf and seed extracts from an edible herb namely Amaranthus viridis L. The extract yields of active components, produced using pure and aqueous methanol, from the leaves and seeds ranged from 5.4 to 6.0 and 2.4 to 3.7%, respectively. The extracts contained appreciable levels of total phenolic contents (1.03 to 3.64...
