UPLC-HRESI-MS and GC-MS analysis of the leaves of .

The alkaloid-rich fraction obtained by fractionation of the crude methanolic extract of the leaves of wild tobacco tree Graham (Solanaceae) was analyzed using UPLC-MS and GC-MS. Anabasine, a piperidine alkaloid, was identified as the major constituent with approximately 60 % (/) of the alkaloid-rich fraction. In addition to anabasine, six secondary metabolites were identified using high-resolution UPLC-MS.

Phytochemical and Biological Evaluations of Boiss. (Araceae).

Background: is a traditional medicinal plant indigenous to Jordan. The present study explores its phytochemistry, antioxidative, antidiabesity, and antiproliferative potentialities.

Materials And Methods: Column chromatography and HPLC-MS analysis were used for its phytochemical evaluation.

Studies on the In Vitro Antiproliferative, Antimicrobial, Antioxidant, and Acetylcholinesterase Inhibition Activities Associated with Chrysanthemum coronarium Essential Oil.

The essential oil of the Jordanian Chrysanthemum coronarium L. (garland) was isolated by hydrodistillation from dried flowerheads material. The oil was essayed for its in vitro scavenging activity using the 1,1-diphenyl-2-picrylhydrazyl (DPPH) method.

Antioxidant, antimicrobial and antiproliferative activities of Anthemis palestina essential oil.

Background: Anthemis palestina (Asteraceae) extends across the Mediterranean region, southwest Asia and eastern Africa. Although traditionally used for several applications, in vitro investigation of biological functions associated with Anthemis palestina essential oil had never been reported.

Methods: The air-dried flowers of Anthemis palestina were subjected to hydrodistillation to yield the oil.

Liquid chromatography-mass spectroscopy and liquid chromatography-ultraviolet/visible photodiode array analysis of selected colchicum species.

An in-house strategy to dereplicate colchicinoid alkaloids was recently developed by our team. It aimed at quickly identifying Colchicum constituents using LC-MS (liquid chromatography-mass spectroscopy) and LC-UV/Vis PDA (liquid chromatography-ultraviolet/ visible photodiode array) techniques. In this project, our goal was to validate the developed method through analysing the alkaloid-rich fractions of three Colchicum species that had been previously studied phytochemically using the traditional bioactivity-guided fractionation methodology.
