Objective: To research the inhibitory effect on SGC-7901 cells of α-pinene, and the related mechanism of α-pinene. Methods: Used the MTT method to detect inhibition rate and western blotting to detect the influence on expression of ATM, Phos-S1981ATM, H2AX, γH2AX, CHK2 and p-CHK2, p53 and phos-p53 cell cycle related protein in SGC-7901 cells. Results: The research found α-pinene could inhibit t...

OBJECTIVE Eucalyptus (Fam. Myrtaceae) is a medicinal plant and various Eucalyptus species possess potent pharmacological actions against diabetes, hepatotoxicity, and inflammation. This study aims to investigate essential oil composition from leaves and flowers of E. microtheca and E. viminalis leaves growing in the Southeast of Iran. MATERIALS AND METHODS The aerial parts of these plants wer...

background ducrosia anethifolia (da) is a medicinal plant traditionally used to treat a wide spectrum of illnesses. da contains a series of antioxidant compounds, including alpha-pinene, which give it a sedative and relaxing effect. in spite of these effects of da, the effects of da essential oil on anxiety and locomotor activity in open field tests have not yet been studied. in the present stu...

introduction & aim: plant growth regulators (pgr) have same effect as natural plant's hormones and can change the main components in plant samples. chaerophyllum aureum l. is related to apiaceae family. experimental: in this paper the qualitative and quantitative composition of the volatile oils of ‎chaerophyllum aureum l. were reported after using different concentrations of iaa and naa ‎...

New particle formation during the oxidation of αand β-pinene (C10H16) by ozone, OH and NO3 was studied by measuring the particle size distributions with a scanning mobility particle sizer (TSI 3936). The results indicate a drastically higher nucleation potential of the ozonolysis than in the reaction with either OH or NO3. On the contrary, the contribution of the individual oxidation reactions ...

Detailed mechanisms have been developed which describe the complete degradation of αand β-pinene. Gas-aerosol absorptive partitioning has been incorporated for 280 oxygenated products, and the mechanism for α-pinene has been used to simulate the time development of ozone, secondary organic aerosol (SOA) and, where applicable, NOX for the conditions of EUPHORE experiments performed at part of th...

Abstract The heat capacity of different mixtures terpenes (α-pinene, β-pinene, limonene oxide) and solvents (acetone, toluene, ethyl acetate) at atmospheric pressure (85.1 kPa atm in Medellin, Colombia) were measured using a microcalorimeter several terpene molar fractions from room temperature to value close the solvent boiling point. analyzed acetone + α-pinene 298.15 323.15 K, toluene oxide ...

background: the genus tanacetum (compositae) is represented by 26 species in the flora of iran, 12 of them are endemic. one report on the analysis of essential oil of tanacetum polycephalum boiss. species has been published. objective: aim of this study is to determine the chemical composition of the hydrodistilled oil of tanacetum pinnatum boiss. of iranian origin for the first time. methods: ...
