BACKGROUND Hyperglycemia is a complicated condition accompanied with high incidence of infection and dyslipidemia. This study aimed to explore the phyto-constituents of Crataegus azarolus var. eu- azarolus Maire leaves, and to evaluate the therapeutic potentials particularly antimicrobial, antihyperglycemic and antihyperlipidemic of the extract and the isolated compound (3β-O-acetyl ursolic aci...

Bioassay-guided fractionation of the MeOH extract of Geum japonicum Thunb. var. chinense using the fatty acid synthase inhibition assay led to the isolation of a new dimeric ellagitannin, gemin G (1), together with six known compounds, gemin A (2), casuarinin (3), pedunculagin (4), potentillin (5) , tellimagrandin II (6), and ellagic acid (7). Their structures were determined on the basis of sp...

Antioxidant potential of Rosa L. leaves methanolic extracts was evaluated in vitro using a spectrophotometric method based on measuring the radical scavenging effect on 2,2-di-phenyl-1-picrylhydrazyl (DPPH) radicals. The contents of ellagic acid, quercetin and kaempferol in the extracts from leaves of seventeen rose species were determined using SPE-RP-HPLC methods. Additionally, total phenolic...

Objectives: The main objective of the present work is to enhance bioavailability ellagic acid (EA) by increasing its dissolution there allowing for exploitation therapeutic effects. Methods: Phytosomes containing EA were prepared anti-solvent precipitation method. phytosomes evaluated drug entrapment efficiency, in vitro release, and excipient interaction studies. Results: Formulation F2 soya l...

Liquid column chromatography, planar chromatography (TLC) on modified and unmodified silica layers, reversed-phase high-pressure liquid chromatography (HPLC), as well as ESI-TOF MS and 1H-NMR have been used for separation, purification and identification of phenolic acids in the barks of Sambucus nigra and Viburnum opulus (Caprifoliaceae). By the use of these procedures three cinnamic acid deri...
