the aim of the present study was to investigate the influence and the mechanisms of cineoleand terpineol on the in-vitro transdermal delivery of huperzine a from microemulsions, andtheir potential synergistic effect on the permeation enhancement. the transdermal deliveryof huperzine a from microemulsions with different concentrations of cineole and terpineolthrough the rat abdominal skin was de...

Staphylococcus aureus causes many severe diseases, such as meningitis, lung infection, and hematogenous osteomyelitis. The prolonged use of antibiotic drugs leads to antimicrobial resistance (AMR), decreasing their effectiveness against S. aureus. Therefore, novel isolated from natural products have been the focus researchers solve that problem. essential oils Vitex trifolia leaf pharmacologica...

Background and objectives: Several natural compounds have been identified for the treatment of leishmaniasis. Due to a few safe drugs and the side effects caused by available chemotherapy, some new drugs for treatment of leishmaniasis are requested. The genus Pulicaria (Asteraceae) is represented in the flora of Iran by five species. Phytochemical studies on Pulicaria species have revealed some...

With use of a conditioning paradigm, the ability of six squirrel monkeys to distinguish between 10 pairs of enantiomers, i.e., odorants that are identical except for chirality, was investigated. As a group, the animals were only able to discriminate between the optical isomers of α-pinene, carvone, limonene, and fenchone, whereas they failed to distinguish between the (+) and (-) forms of β-cit...

The antibacterial activity and antioxidant effect of the compounds α-terpineol, linalool, eucalyptol and α-pinene obtained from essential oils (EOs), against pathogenic and spoilage forming bacteria were determined. The antibacterial activities of these compounds were observed in vitro on four Gram-negative and three Gram-positive strains. S. putrefaciens was the most resistant bacteria to all ...

Background & Aim: Myrtle (Myrtus communis L.), is an important medicinal plant that is used for pharmacological uses and conservation of environments (for example preventing the soil erosion) regards to its specific condition habitat. Experimental: In this research, phytochemical variations of the essential oils from different populations of myrtle collected from Fars (Saydan, Cheshme-Ali, and ...

Essential oils (EOs) of the leaves three Eugenia punicifolia specimens from two different Reservation Parks, namely Parque Nacional das Nascentes do Rio Parnaíba (EpNRP-I and EpNRP-II) da Chapada Mesas (EpCM), in state Maranhão, Brazil, were extracted by hydrodistillation investigated gas chromatography coupled to mass spectrometry. Principal component hierarchical cluster analyses indicated di...

In this study, the essential oil (EO) from peel of Greek citrus hybrid Citrus sinensis cv New Hall - aurantium was studied in terms its antimicrobial properties as well effect on Saccharomyces cerevisiae. According to analysis EO, 48 compounds are contained it, with main being limonene, β-pinene, myrcene, α-pinene, valencene, and α-terpineol. As regards properties, EO evaluated against nine hum...
