This study examined five species of the Lamiaceae family, Origanum vulgare L., dictamnus majorana Mentha spicata L. and Lavandula angustifolia one Hypericaceae Hypericum perforatum for their potential to enhance health wellbeing or prevent diseases. An analysis secondary metabolites was performed by mass spectrometry HPLC coupled with diode array detection determine phenolic compounds included ...

the effect of mentha spicata l. extract on the corrosion behaviour of carbon steel in 1.0 m hcl solution was investigated using polarization, electrochemical impedance spectroscopy (eis) and electrochemical noise (en) techniques. the solution containing 250 ppm of the ethanolic solution of extract showed the highest inhibition efficiency (ie). the effect of temperature on the rate of corrosion ...

1. In the AÊ land islands of SW Finland, the parasitoid Cotesia melitaearum (Wilkonson) is a specialist on the Glanville fritillary butter ̄y, Melitaea cinxia (L.), which uses two host plants, Plantago lanceolata (L.) and Veronica spicata (L.). 2. Extensive survey data on the butter ̄y and parasitoid populations collected in 1994±97 were used to examine possible associations of parasitoid coloniz...

HIGHLIGHTS Essential oil contents of T. spicata, L. X Intermedia, S. macrantha and R. officinalis was determined. The main components these plants were monoterpenoid spicata showed strong effects against three microorganisms.
