Front Cover: In article number 2100065 by Magdalena Maria Kleybolte and Malte Winnacker, the synthesis of β-pinene-based polyesteramides their monomers is investigated significantly improved. Thus, further optimization analysis β-pinene lactam as well its copolymerization with ε-caprolactone represents a significant advance for better understanding methods sustainable polyesteramides.

The essential oils associated with the flowers of Tithonia diversifolia (Hemsl.) A. Gray were extracted and characterized via hydrodistillation and Gas Chromatography. Hydrodistillation was done in an all-glass Clevenger-type apparatus. The extracts from the hydrodistillation were subjected to gas chromatography where the components of the essential oils were separated based on their molecular ...

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 ‎...

Atmospheric oxidation of monoterpenes contributes to formation of tropospheric ozone and secondary organic aerosol, but their products are poorly characterized. In this work, we report a series of outdoor smog chamber experiments to investigate both gaseous and particulate products in the ozone oxidation of four monoterpenes: α-pinene, β-pinene, 13-carene, and sabinene. More than ten oxygenated...

Pine resin has been used as a traditional health-promoting medicinal food in Turkey and some countries for centuries. In the present study, antioxidant potential monoterpene profile of 13 pine samples purchased from herbalists different provinces were investigated. According to analysis results, there differences between samples, especially terms color properties. The experimental results demon...

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 ...

This study aimed to evaluate effects of elevation and phenological stage on essential oil components of Teucrium polium L. and Teucrium orientale L. belonging to the Lamiaceae family. The aerial parts of the grown plants in two ranges of elevation including 2000-2500 and 2500-3000 m above sea level were harvested at three time-points, including end of vegetative, flowering, and seed filling sta...
