Dependence of monoterpenoid emission and fractional composition on stomatal conductance (G(V)) was studied in Mediterranean conifer Pinus pinea, which primarily emits limonene and trans-beta-ocimene but also large fractions of oxygenated monoterpenoids linalool and 1,8-cineole. Strong decreases in G(V) attributable to diurnal water stress were accompanied by a significant reduction in total mon...

The objective of the current study was to evaluate altitudinal variability in chemical compounds, nematicidal, insecticidal, herbicidal, and antifungal activity essential oils H. coronarium collected from four different habitats Tarai Kumaun region Uttarakhand. Essential were hydro-distilled rhizomes coronarium, their yield varied 0.05 0.25% (v/w). Based on GC-MS analysis, major compounds obser...

abstract: chemical composition of lavandula angustifolia was studied by solvent free microwave extraction (sfme) and hydrodistillation (hd) methods. 1, 8-cineole (42.7% and 37.9%), camphor (26.1% and 21.3%) and borneol (31.2% and 21.6%) were the major compounds that obtained by sfme and hydrodistillation, respectively. the antibacterial activity of extracted oils was investigated against gram-p...
