In vitro plantlets and callus of M. longifolia were established and their volatile constituents characterized by GC-MS analysis of their headspaces (HSs) and essential oils (EOs). Significant quali-quantitative differences were found in the aromatic fingerprints in comparison with the M. longifolia parent plants. In fact, limonene and carvone were the main constituents in the EOs of the mother ...

results the chemical analysis of s. khuzestanica essential oil revealed the presence of carvacrol (94.1%) as its main component. the inhibition zone diameters of s. khuzestanica essential oil and carvacrol dose-dependently increased. the minimum inhibitory concentration (mic) values of s. khuzestanica essential oil and carvacrol were 0.14 ± 0.08 µl/ml and 0.09 ± 0.04 µl/ml, respectively. s. khu...

There is a thriving market for reduced-risk pesticides. Many pesticides containing conventional active ingredients such as chlorpyrifos and diazinon have been phased out of urban markets. Their widespread use in both agriculture and urban areas had led to increased exposures and unacceptable risks (FQPA 1996; NRC 1993; Wright et al. 1994). They were also a threat to water quality in many areas ...
