Comparative antisickling and antioxidant activities of cultivars in relation to their metabolite profiling using LC/MS.

is native to South America and is cultivated worldwide mostly for its medicinal benefits. The plant is used traditionally in respiratory disorders such as dry cough, in the treatment of fever and stomach pain, and as an antimicrobial and analgesic. The antisickling and antioxidant effects of the flowers of (Kunth) Dugand (red) and cultivar alba (white) were compared using an assay in 2% sodium metabisulfite sickling induction model, DPPH, and metal chelation assays.

New Pregnane Glycosides Isolated from Lavranos as Inhibitors of α-Glucosidase, Pancreatic Lipase, and Advanced Glycation End Products Formation.

Lavranos (Family Asclepiadaceae) is an endemic herb in Yemen and Saudi Arabia, traditionally used to treat diabetes, abdominal pain, and stomach ulcers. Different extracts, fractions, and main constituents of were evaluated for their inhibitory activity against key enzymes in diabetes and hyperlipidemia, i.e.

Two new cytotoxic furoquinoline alkaloids isolated from Aegle marmelos (Linn.) Correa.

Two new cytotoxic furoquinoline alkaloids were isolated from the leaves of Aegle marmelos (Linn.) Correa; one from the total alkaloidal fraction (acid/base shake-out method) of the CHCl extract and identified as 7,8-dihydroxy-4-hydrofuroquinoline and named trivially as Aegelbine-A. The other new alkaloid isolated from the pet.
