Currently the drug of choice for combating the formation of dental plaque in these animals, the etiologic agent of the disease, is chlorhexidine, which has several side effects reported. Thus, surveys are conducted throughout the world in or...

Apical meristems and nodal plant parts were used for mass propagation of Peperomia obtusifolia. Different concentrations of BAP (6-benzylaminopurine), TDZ (Thidiazuron) and KIN (Kinetin) were used in MS medium. The highest shoot proliferation and multiplication formation occurred in the MS basal medium containing 1.0 mg/mL BAP. Maximum number of shoots and shoot lengths were 9.80 ±0.50 and 35.4...

Lemon balm (Melissa officinalis L.), a member of Lamiaceae family, is an important medicinal plant that has many useful properties. Micronutrients are necessary in low dose for the growth and the development of plants. Present research was conducted to study the effects of micronutrients including manganese (Mn) and copper (Cu) on morpho-physiological traits and essential oil of lemon balm. Fie...

The influence of second-generation products on the particle mass yield of β-caryophyllene ozonolysis was systematically tested and quantified. The approach was to vary the relative concentrations of firstand secondgeneration products by adjusting the concentration of ozone while observing changes in particle mass yield. For all wallloss corrected organic particle mass concentrations Morg of thi...

The aim of this research was to determine chemical composition and insecticidal activity of the essential oil of Illicium pachyphyllum fruits against two grain storage insects, Sitophilus zeamais and Tribolium castaneum, and to isolate any insecticidal constituents from the essential oil. The essential oil of I. pachyphyllum fruits was obtained by hydrodistillation and analyzed by GC-MS. A tota...
