Phytochemical Investigation of New Algerian Lichen Species: Nimis.

The present study provides new data concerning the chemical characterisation of Nimis, a rare Mediterranean species belonging to the family Physciaceae. The phytochemical screening was carried out using GC-MS, HPLC-ESI-MS-MS, and NMR techniques. Hot extraction of n-hexane was carried out, followed by separation of the part insoluble in methanol: wax (WA-hex), from the part soluble in methanol (ME-hex).

Chemical Composition and Antibacterial Activity of Moldenke Essential Oil from Different Regions of Angola.

The purpose of the study was to determine the chemical composition and antibacterial activity of Moldenke essential oils (EOs) collected in different regions of Angola. Antibacterial activity was evaluated using the agar wells technique and vapour phase test. Analysis of the oils by GC/MS identified thirty-five components representing 67.
