Ricinus communis has been utilized traditionally as medicine to treat inflammatory related diseases including wounds, sores, and boils. The leaves of R. communis were sequentially extracted with n-hexane, dichloromethane, acetone, and methanol using serial exhaustive extraction method. Antioxidant activity of all crude extracts was quantitatively measured against 2,2'-azino-bis (3-ethylbenzothi...

The title compound, C18H24NO3 (+)·Cl(-)·H2O, was synthesized by the reaction of propranolol hydro-chloride with acetyl chloride in chloro-form followed by slow evaporation in air. In the cation, the dihedral angle between the planes of the naphthalene ring system and the acetate group is 71.1 (2)°. An intra-molecular N-H⋯O hydrogen bond results in the formation of a non-planar pseudo-ring, with...

Induction of cytotoxicity and internucleosomal DNA fragmentation by 4-allyl-2-methoxyphenol (eugenol, EUG), 2-methoxy-4-methylphenol (MMP), 3,3'-dimethoxy-5,5'-di-2-propenyl-1,1'-biphenyl-2,2'-diol (bis-EUG) and 3,3'-di-methoxy-5,5'-dimethyl-1,1'-biphenyl-2,2'-diol (bis-MMP) were investigated in HL-60 leukemia cells. The 50% cytotoxic concentrations (CC50) for EUG, MMP, bis-EUG and bis-MMP were...

bisphenol a, 2,2-bis(4,4-dihyroxyphenyl propane) is the raw material for the production of important synthetic polymers such as epoxyresins, polycarbonates and polysulphones. during the last twenty years the anual production of bisphenol-a has been continuously increasing. a,b,c cqrves shows the consumption pattern of bisphenol-a (19601972) • epoxy resins are used for the production of adhessiv...

essential oils are considered as very complex natural mixtures containing numerous components at quite various concentrations. lythrum salicaria has not been previously subjected to examination of its volatile oil. the present study was carried out to evaluate the essential oil composition of the flowering aerial parts of the plant by using conventionally hydro-distillation (hd) and microwave a...

The preparation of palladium(II) complexes of 3,5-diacyl-1,2,4-triazole bis(thiosemicarbazone) (H2L2), 2,6-diacylpyridine bis(thiosemicarbazone) (H2L3) and benzyl bis(thiosemicarbazone) (H2L4) is described. The new complexes [PdCl2(H2L2)] (1), [PdCl2(H2L3)] (2) and [PdL4].DMF (3) have been characterized by elemental analyses and spectroscopic studies (IR, 1H NMR and UV-Vis). The crystal and mol...
