Essential oils are applied extensively in producing of perfumes, cosmetics, foods, beverages and confectioneries and as ingredients of disinfectants and insecticides. Experimental: Essential oil are obtained by several isolation methods, such as hydrodistillation (HD...

OBJECTIVE Perovskia abrotanoides Karel, belongs to the family Lamiaceae and grows wild alongside the mountainous roads inarid and cold climate of Northern Iran. The anti-tumor activity of P. abrotanoides root extract has been shown previously. This study was designed to examine in vitro anti-proliferative and pro-apoptotic effects of flower extract of P. abrotanoides on MCF-7 and Hela cell line...

Total DNA was extracted from 41 species (20 genera) of the subfamily Nepetoideae (family Labiatae). Using rbcL-specific primers, the rbcL gene wsa amplified by polymerase chain reaction (PCR) and sequenced directly. RbcL sequences were evaluated with character state (maximum parsimony; PAUP) and distance methods (neighbour-joining; MEGA). In agreement with classical systematics all taxa studied...

control of stored-product insect by gamma radiation could be enhanced by other possible techniques such as essential oils as effective alternatives to chemical insecticides. in this study, the efficiency of gamma radiation combined with perovskia atriplicifolia (benth) was verified to assess their enhanced antifeedant effect against the tribolium castaneum (herbst). flour disc bioassay was empl...
