The water-distilled essential oil from dried aerial parts of achillea tenuifolia Lam. Was analysed by GC and CG/MS. 48 Components were characterized representing 88% of the total oil. Camphor (18%), 1,8-cineole + limonene (9%) and spathulenol (7%) were the major constituents of the oil obtained in a yield of 0.23%.

Anethum graveolens Linn. (Umbelliferae, A. graveolens) is a widely used spice with a long history of traditional medicinal use for the treatment of various ailments. The biosynthesis of secondary metabolites in medicinal and aromatic plants is affected by abiotic stresses such as water deficit. This study was carried out to evaluate seed yield and essential oil of dill under five irrigation dis...

Sequential ultrasound-microwave associated extraction (SUMAE) is a combination of ultrasound waves and microwaves energies in which ultrasonic extraction is used as a pretreatment. It was performed to extract essential oil from Zataria multiflora. The extraction conditions were optimized by response surface methodology (RSM) and Central Composite Design (CCD). The antioxidant and antibacterial ...

The studies conducted in 2007–2008 were aimed to assess how the developmental stage of common oregano affected the quality and quantity of the herb yield. The field experiment was established with the use of random blocks in four repetitions. Oregano was grown from seeding produced in a greenhouse. Herbage harvest of one-year-old plants was conducted before flowering, in budding phase, at the b...
