the composition of essential oil of leaves of the male and female shrubs of juniperus chinensis l. (growing in isfahan) was analyzed by gas choromatography(gc) and gc-mass spectrometery (ms). the main constituents of leaf oil of the male shrub were: bornyl acetate (26.1%), sabinene (18.3%), trans-sabinyl acetate (11.1%), myrcene (9.2%), limonene (6.1%), elemol (5.5%), α-cadinol (2.3%), δ-cadine...

The composition of the essential oil hydrodistilled from the aerial parts of 18 individual Artemisia herba-alba Asso. plants collected in southern Tunisia was determined by GC and GCMS analysis. The oil yield varied between 0.68% v/w and 1.93% v/w. One hundred components were identified, 21 of of which are reported for the first time in Artemisia herba-alba oil. The oil contained 10 components ...

conclusions according to antioxidant activity outcomes, the amount of ic50s of aqueous extracts of flower and stem and also butylated hydroxyl toluene (bht) as standard were 232.34, 63.25 and 45.59 ppm respectively. ultimately, it was highlighted that antioxidant activity of aqueous extract of flower was weaker than stem. results sixty one compounds were identified in the essential oil of the f...

The methanolic leaf extract of Artemisia parviflora (APLE) tested against Anopheles stephensi larvae and pupae and recorded the mortality rate, LC 50 and LC 90 values. This investigation revealed that this leaf extract possess higher toxicity against Anopheles stephensi. The biological activity of the plant extract might be due to the presence of active compounds âCaryophyllene, germacrene D, C...
