Chemical composition, antibacterial, antioxidant, and anticholinesterase activities, and , of the essential oil of Algerian endemic species Murb.

This study investigated the chemical composition and biological activities of essential oils extracted from Daucus biseriatus collected from the Algerian Sahara. Gas chromatography-mass spectrometry identified 57 compounds, constituting 97.09% of the oils, with myristicin (23.

A novel benzimidazole and other constituents with antiproliferative and antioxidant properties from Thymelaea microphylla Coss. et Dur.

A new compound (microphybenzimidazole, 7) along with the six known compounds matairesinol (1), prestegane B (2), umbelliferone (3), daphnoretin (4), microphynolide A (5) and microphynolide B (6) were isolated from Thymelaea microphylla. The structures of the pure compounds were elucidated by spectroscopic and mass-spectrometric analyses, including 1D-, 2D-NMR, and HPLC-TOF/MS. Compounds 2 and 4, as well as three fractions (F6, F6-C5, and F6-W42) obtained from a 50% (v:v) CHCl:MeOH extract exhibited a selective activity against rat brain glioma cells (C6).

Chemical composition and antibacterial activity of the essential oils from Launaea resedifolia L.

Background: Several species of the genus Launaea are used in folk medicine such as in bitter stomachic, skin diseases, and reported to have antitumor, insecticide, and cytotoxic activities. The antimicrobial activities of coumarin constituents and the neuropharmacological properties have been investigated as well. In this study, the chemical composition of essential oils from Launaea resedifolia L.

A myristicin-rich essential oil from Daucus sahariensis growing in Algeria.

The essential oils obtained by hydrodistillation from leaves and fruits of Daucus sahariensis Murb. were analyzed by GC/MS. The main constituents of the essential oil from the leaves were myristicin (34.
