Introduction Conclusions References
Chemical composition of the essential oils extracted from the leaves, stems, flowers and seeds of Heracleum rechingeri Manden. were analyzed by GC and GC/MS. Twenty-four components were characterized for the leaf oil with Octyl acetate(47.2%), Octanol(15.2%) and E-caryophyllen (5.7%) as the main constituents. 25 compounds were identified in the stem oil with Elemicin (65.3%), Octyl acetate (13...
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 esse...
The study was conducted to determine fennel essential oil (FEO) yield, composition, and antioxidant activity during four different maturation stages of umbels with seeds (1st stage: immature-pasty; 2nd premature-waxy; 3rd mature-fully ripe; 4th only), leaves wild (Foeniculum vulgare Mill. subsp. vulgare) from the Montenegro coast. maximum yield found in premature at waxy stage (4.76 mL/100 g p....
