Abstract Numerous studies highlighted the impact of natural products, particularly phytosterols, in wound healing while providing less expensive alternatives to chemically synthesized drugs, with side effects. Centaurea pumilio L. (family Asteraceae) is a rare and endangered species genus few reports concerning its chemistry. Our phytochemical investigation for non-polar fraction aerial parts l...

Periploca aphylla (PA), an interesting Saudi medicinal plant, is used in folk medicine to treat urticaria, cerebral fever, tumors, and swelling. To prove its use medicine, two different extracts from the aerial parts of plant: chloroform P-1, n-butanol P-2 were subjected biological assays screen peroxisome proliferator-activated receptors (PPAR? PPAR?) agnostic, anti-inflammatory, antioxidant, ...

Main aim is to evaluate the genotoxic potentials of three classes of natural products, a sesquiterpene lactone (cynaropicrin), a saponin (stigmast-7en-3 -ol-glucopyranoside) and a steroid (stigmasterol), at low doses, using the Homozygotization Index test (HI). This short-term test, deals with the determination of alterations in mitotic crossing-over frequencies eventually involving heterozygou...

Phytochemical and biological studies were carried out the stem bark of Cratoxylum arborescens collected from Sarawak, Malaysia. Chromatographic separation of the plant extracts led to the isolation of three xanthones, -mangostin (1), -mangostin (2) and fuscaxanthone C (3) together with the commom stigmasterol. The structural elucidation of the compound was determined by detail spectroscopic a...

Objective: Firstly to screen the antihyperglycaemic activity of petroleum ether extract (PBM) of Bacopa monnieri. Finally to examine the antihyperglycaemic activity, in-vivo antioxidant potential, effect on glycosylation of hemoglobin, estimation of glycogen content in liver and in-vitro peripheral utilisation of glucose of stigmasterol (ST), a phytosterol isolated from PBM. Methods: Antihyperg...
