Earlier, we reported the formation of unidentified strong irritants in reaction mixtures of terpenes and ozone. The identified products included aldehydes, ketones and carboxylic acids. Here we report the effects of relative humidity and reaction time on irritant formation in our flow reaction system using limonene and isoprene. Upper airway irritation was measured in mice (via reduction of res...

Renewable natural and synthetic basic substances can be used to produce biodegradable polymers. Several methods of the polymerization terpene limonene have been evaluated. The evaluated are radical polymerization, cationic thiol-ene polymerization. free-radical with azobisisobutyronitrile (AIBN) as an initiator was carried out. out using AlCl3 a catalyst. copolymerization mercaptoethanol, 2-mer...

Abstract Background (−)-Limonene, one of cyclic monoterpenes, is an important renewable compound used widely as a key building block for the synthesis new biologically active molecules and fine chemicals. (−)-Perillamine, derived from (−)-limonene, highly useful synthon constructing more complicated functionally relevant Aim We aimed to report sustainable efficient method regiospecific C–H amin...

Alyssum strigosum Banks & Sol. subsp. and A. cedrorum (Schott Kotschy) Dudley, which are two subspecies of with their morphological, anatomical, palynological traits, were presented in detail this study. The anatomical analysis has been carried out using handmade sections. transverse sections roots showed that have similar characters as primer structure. stem reflected the typical dicotyled...

Limonene is ionized by circularly polarized 420 nm femtosecond laser pulses. Ion mass and photoelectron energy spectra identify the dominant (2 + 1) multiphoton ionization mechanism, aided by TDDFT calculations of the Rydberg excitations. Photoelectron circular dichroism measurements on pure enantiomers reveal a chiral asymmetry of ±4 %.

Background: A number of aromatic medicinal plants used for treating infection disease have been mentioned in different phytotherapy manuals due to their availability, fewer side effects, and reduced toxicity.Dracocephalum L is one of the most important genuses of Lamiaceae.The aim of our study was to evaluate the chemical compositions of Dracocephalum Lind...
