The present work aimed to study the composition and antimicrobial properties of essential oil Helichrysum ibityense leaves (HIEO). HIEO was extracted by hydrodistillation from fresh with a yield 1.9%. It had relative density 0.9247 at 20℃, refractive index 1.4706, an optical rotation -0°33, acid 2.10 ester 54. Gas chromatography analysis/flame ionisation detection identified 17 components, repr...

Mono- and diterpenoids are of great industrial and medical value as specialty chemicals and pharmaceuticals. Production of these compounds in microbial hosts, such as Escherichia coli, can be limited by intracellular levels of the polyprenyl diphosphate precursors, geranyl diphosphate (GPP), and geranylgeranyl diphosphate (GGPP). To alleviate this limitation, we constructed synthetic operons th...

3-Benzylmenadiones were obtained in good yield by using a blue-light-induced photoredox process the presence of Fe(III), oxygen, and γ-terpinene acting as hydrogen-atom transfer agent. This methodology is compatible with wide variety diversely substituted 1,4-naphthoquinones well various cheap, readily available benzyl bromides excellent functional group tolerance. The benzylation mechanism was...

The kinetics of antibacterial activity cajuput oil (Melaleuca cajuputi) to E. coli, B. cereus, and S. aureus were investigated. aim this study was determine the reaction orders as an agent. extraction conducted by water-steam distillation. yield 0.88%. GC-MS analysis showed that contained β-ocimene (19.35%), 1.8-cineole (17.67%), limonene (12.09%), β-caryophyllene (9.51%), γ-terpinene (8.93%), ...

The literature shows that the monoterpenes are great candidates for the development of new drugs for the treatment of various pathological processes, including painful conditions. The gamma terpinene (γ-TPN) is a monoterpene present in plant species that have multiple pharmacological properties and has structural similarity to antinociceptive monoterpenes, such as limonene and alpha-phellandren...
