background: biosynthesis and metabolism of phytochemicals in medicinal and aromatic plants are vigorously affected by different abiotic elicitors including chemicals. objective: this experiment was designed to investigate the effects of three levels of copper sulfate (cu: 0, 5, 25 mg kg-1) and zinc sulfate (zn: 0, 10, 50 mg kg-1) and their combinations on yield, chemical compositions of essenti...

background & aim: sweet basil (ocimum basilicum), a plant that is extensively cultivated in some countries, is used to enhance the flavour of salads, sauces, pasta, confectioneries and other products as both a fresh and dried herb. the effect of foliar application of jasmonic acid and reduced irrigation on essential oil yield and chemical components of two iranian landrace of basil (ocimum ...

This study sought to carry out a screening of the polyphenols from the aerial parts of four samples of Ocimum basilicum. HPLC-MS method was used to investigate the presence of phenolic compounds in the studied samples; caftaric, cafeic, chlorogenic, p-coumaric acids and rutin were identified. The total polyphenolic content was determined by using the Folin-Ciocalteu reagent, the flavonoid and t...

Purpose of the research was to estimate state varietal resources and adaptive-and-productive potential basil plants. Methods. Field, laboratory, statistical calculation-analytical. The field work included marking out experimental plot work. laboratory method used analyze plants, assess quality crop, study physical, chemical microbiological properties soil. Statistical analytical calculation met...

In this study, the in vitro anticholinesterase activity of the volatile oils of both O. basilicum and O. africanum was investigated and both samples showed significant activity. The major constituents of the two oils were isolated using several column chromatographies. Linalool, 1,8-cineol and eugenol were isolated from the volatile oil of O. basilicum and camphor was isolated from the volatile...
