In this study, the chemical composition of essential oils obtained from aerial parts Thymus longicaulis subsp. naturally grown in Turkey were analyzed by GC and GC-MS differences terms chemotaxonomy discussed. The main compounds T. 1,8-cineole (30.1%), linalool (18.0%), β-pinene (17.3%) (E)-β-ocimene (%12.6%) Hierarchical cluster analysis was performed examining oil studies 34 samples belonging...

the genus hypericum is one of the most important medicinal plants that contain 17 species in iran, three of them are endemics. this paper reports the essential oil composition of six hypericum species from iran. the essential oil analysis of a number of the studied plants has already been reported but their report from iran may be valuable for scientists.  samples collected between june and aug...

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 inhibition of enzymes involved in the breakdown of carbohydrates is considered a therapeutic approach to the management of type-2 diabetes. This study sought to investigate the effects of essential oil from clove bud on α-amylase and α-glucosidase activities. Essential oil from clove bud was extracted by hydrodistillation, dried with anhydrous Na2SO4 and characterized using gas chromatograp...

The kinetics of antibacterial activity cajuput oil (Melaleuca cajuputi) to E. coli, B. cereus, and S. aureus were investigated. aim this study was determine the reaction orders as an agent. extraction conducted by water-steam distillation. yield 0.88%. GC-MS analysis showed that contained β-ocimene (19.35%), 1.8-cineole (17.67%), limonene (12.09%), β-caryophyllene (9.51%), γ-terpinene (8.93%), ...
