Allelopathic effects of juglone and walnut leaf extracts from Persian walnut (Juglans regia L.) on yield, growth, chemical and plant nutrient element composition of the day-neutral strawberry (Fragaria × ananassa L.) cultivar Fern were investigated as part of an effort to identify tolerant species to plant adjacent to walnut. Strawberry plants were treated with juglone (5-hydroxy-1.4 naphthoqui...

Pentacyclic triterpenes are secondary plant metabolites widespread in fruit peel, leaves and stem bark. In particular the lupane-, oleanane-, and ursane triterpenes display various pharmacological effects while being devoid of prominent toxicity. Therefore, these triterpenes are promising leading compounds for the development of new multi-targeting bioactive agents. Screening of 39 plant materi...

In the present study, the Allium cepa chromosome assay was employed as a preliminary test to investigate the mutagenic and antimutagenic potential of three plants, namely Clinacanthus nutans, Adhatoda vasica, and Carica papaya, used by traditional practitioners in Malaysia against a direct acting mutagen-Methyl Methanesulphonate (MMS). Onions were planted in various treatment groups: plant extr...

In the present study, different aerial parts from twelve Amazonian plant species found in the national Institute for Amazon Research’s (InpA’s) Adolpho Ducke Forest Reserve (in Manaus, Amazonas, Brazil) were collected. Separate portions of dried, ground plant materials were extracted with water (by infusion), methanol and chloroform (by continuous liquidsolid extraction) and solvents were remov...

Background & Aim: Very studies results show that many plants can be used safety and successfully to treat bacterial diseases without presenting the disadvantages affects and antibiotic resistance. Eucalyptus globulus and Malva neglecta are native plants in Iran that due to containing different chemical compounds have been antimicrobial activity against some bacteria. The aim o...

On a global scale, people have used plants to treat diseases and infections, and this has raised interest on the plant biodiversity potencial in the search of antimicrobial principles. In this work, 75 crude n-hexanes, dichloromethane and methanol extracts from the aerial parts of 25 plants belonging to four botanical families (Asteraceae, Euphorbiaceae, Rubiaceae and Solanaceae), collected at ...

Cassia auriculata and Aegle marmelos are used extensively in the indigenous system of medicine as an anti-diabetic agent. The current investigation focuses on the serum insulin augmentation, anti-hyperglycemic and anti-hyperlipidemic property of a combined aqueous extracts of C.auriculata and A.marmelos on streptozotocin induced diabetic rats. The diabetes induced animals were fed with plant ex...

a. calamus that grows in province of baluchistan and kerman in iran plays a major role in the revival of traditional medicine. despite the useful role of this plant in many ailments, its anti-bacterial properties are not well understood. in this study, we investigated anti-bacterial activities of rhizomes ware of a. calamus against various strains of bacteria such as staphylococcus aureus and e...

Fourteen plant species collected in Iran and selected mainly on the basis of their antimicrobial and/or antifungal activities were evaluated for in vitro antiplasmodial and cytotoxic effects in a study designed to screen plant extracts with selective activity against Plasmodium falciparum. The methanol extracts of nine of the species tested exhibit activity against Plasmodium falciparum (MIC va...

Antibiotic resistance is a persistently emerging problem all over the world. The constituents of therapeutic plant extracts play a key role in antimicrobial drug discovery. Extracts of 36 medicinal plant species of Pakistan origin that belong to 33 genera and 24 families were tested against the bacterial strains Staphylococcus aureus and Pseudomonas aeruginosa. In addition the extracts of 23 pl...
