Germacrene C was found by GC-MS and NMR analysis to be the most abundant sesquiterpene in the leaf oil of Lycopersicon esculentum cv. VFNT Cherry, with lesser amounts of germacrene A, guaia-6,9-diene, germacrene B, b-caryophyllene, a-humulene, and germacrene D. Soluble enzyme preparations from leaves catalyzed the divalent metal ion-dependent cyclization of [1-3H]farnesyl diphosphate to these s...

Mikania laevigata leaves are used worldwide as herbal medicines. Our study investigates the production differences among three different genotypes of this herb: genotypes’ influence on essential oil yield, chemical composition, and plant tissues involved in secretion compounds produced by leaves. The performed analysis during summer winter seasons. Plants were grown under an organic cultivation...

The constituents of the essential oil of Stachys laxa Boiss. & Buhse growing wild in Iran were investigated by GC-MS for the first time. Thirty-three constituents were identified. Germacrene-D (40.1%), b -caryophylene (16.7%), b -phellandrene (5.5%), caryophyllene oxide (4.6%), linalool (3.2%) and ?-cadinol (2.6%) were found to be the major constituents of the oil.

The essential oil of Stachys lavandulifolia Vahl (Lamiaceae) was isolated by hydrodistillation of the aerial parts of the plant, with a yield of 0.25%. The chemical composition of volatile oil was analyzed by capillary GC and GC/ MS. The main components were germacrene-D (13.2%), ?-phellandrene (12.7%), ?-pinene (10.2%), myrcene (9.4%), ?-pinene (8.4%) and Z-?-ocimene (5.8%).

The volatile constituents of the aerial parts of Varthemia. persica DC. var. persica, growing wild in Iran, were investigated by GC-MS. Sixty seven constituents were identified. ?-Cadinene (9.7%), Selin-11-en-4-?-ol (5.30%), Germacrene D (4.9%), Bicyclogermacrene (4.7%), ??Muurolene (4.7%), ?-Eudesmol (4.52%), ?-Himachalen oxide (3.6%), ?-Eudesmol (3.54%), ?-Bourbonene (3.21%) were found to be...
