Chemical composition of the Essential oil of Litsea resinosa blume and acetylcholinesterase activity

Abubakar Siddiq Salihu

Abstract

The essential oil of Litsea resinosa Blume (Lauraceae) was obtained by hydrodistillation and was fully characterized by gas chromatography (GC-FID) and gas chromatography-mass spectrometry (GC-MS). A total of twenty-eight components were identified in the essential oil, which made up 90.8% of the total oil. The essential oil consists mainly of β-caryophyllene (22.5%), α-humulene (15.4%), caryophyllene oxide (9.2%), germacrene D (5.6%), and β-selinene (5.0%). The essential oil showed significant activity against acetylcholinesterase with a percentage inhibition of 72.4%. Keywords: Litsea resinosa, Lauraceae, essential oil, caryophyllene, acetylcholinesterase..

Chemical constituents computational studies and bioactivities of four Knema Species Myristicaceae

Abu Bakar Siddiq Salihu

Abstract

The purpose of this study was to investigate essential oils content, phytochemicals, computational modelling and bioactivities of four Knema species (Myristicaceae). Essential oils were extracted via hydrodistillation and were analyzed using gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). Phytochemicals were isolated using silica gel column chromatography and their chemical structures were elucidated via spectroscopic methods including nuclear magnetic resonance, infrared spectroscopy, mass spectrometry, and ultraviolet-visible spectroscopy. Computational studies were performed to assess the binding of isolated compounds to acetylcholinesterase (AChE) and 5-lipoxygenase (5-LOX), and their antibiofilm activities. The major components of the four Knema essential oils were as following: K. intermedia (_-muurolol, 20.1%), K. malayana (_-cadinene, 20.2%), K. hookeriana (_-caryophyllene, 26.2%), and K. furfuracea (bicyclogermacrene, 23.1%). Phytochemical investigati.....
