Polygonum minus (Polygonaceae), generally known as 'kesum' in Malaysia is among the most commonly used food additive, flavoring agent and traditionally used to treat stomach and body aches. Raw or cooked leaves of P. minus are used in digestive disorders in the form of a decoction and the oil is used for dandruff. The pharmacological studies on P. minus(More)
Organotin(IV) carboxylate complexes derivative of 3-(dimethylamino)benzoic acid, 3[N(CH3)2]C6H4COOH have been successfully synthesized. Two types of diorganotin(IV) complexes, [{3-[N(CH3)2]C6H4COO(R)2Sn}2O]2 dimer (R= methyl 1, butyl 3) and {3-[N(CH3)2]C6H4COO}2 (C4H9)2Sn, 2 (monomer) as well as 3-[N(CH3)2]C6H4COO(C6H5)3Sn, 4 were successfully synthesized(More)
The asymmetric unit of title compound, [Fe(C(5)H(5))(C(9)H(12)N(3)S)], contains two crystallographically independent mol-ecules, A and B. The two cyclo-penta-dienyl (Cp) rings are parallel to each other in both mol-ecules, forming dihedral angles of 2.3 (3) and 1.0 (3)°, respectively, and adopt an eclipsed conformation. The mean plane of the semicarbazone(More)
Hymenocallis littoralis (Jacq.) Salisb (Melong kecil) commonly known as 'Spider Lily' is an herbaceous plant from the family Amaryllidaceae. Study was carried out to determine the effect of H. littoralis leaf extract on the growth and morphogenesis of two pathogenic microbes, Candida albicans and Escherichia coli. The leaf extract displayed favourable(More)
In the title compound, [Fe(2)Zn(C(5)H(5))(2)(C(8)H(9)N(3)S)(2)]·CH(3)OH, the dihedral angles between the substituted and unsubstituted cyclo-penta-dienyl rings are 89.34 (8) and 85.73 (9)°, respectively. The two Zn/S/C/N/N five-membered rings adopt envelope conformations, with the Zn(II) atom at the flap. Each methanol solvent mol-ecule is linked to three(More)
The asymmetric unit of the title compound, [Fe(C(5)H(5))(C(7)H(8)N(3)S)], consists of two crystallographically independent mol-ecules, A and B. The cyclo-penta-dienyl (Cp) rings in both mol-ecules adopt an eclipsed conformation and are parallel to each other, forming dihedral angles of 2.5 (3) and 1.1 (3)°, respectively. The mean plane of the semicarbazone(More)
OBJECTIVE To investigate the antihyperlipidemic, antioxidant, and cytotoxic effect of aqueous and methanol extract of leaves of Polygonum minus. MATERIALS AND METHODS Acute antihyperlipidemic effect was studied on chemically induced hyperlipidemic rat model. Treated groups received aqueous and methanol extract of leaves of P. minus respectively (1000(More)
In the title compound, [Fe2Zn(C5H5)2(C7H7N3S)2], the Cp rings of each ferrocene residue have a nearly eclipsed conformation. The two thiosemicarbazone ligands each coordinate the Zn atom in a bidentate mode via the N and S atoms, thereby defining a distorted tetrahedral environment. N—H S, N—H N, C—H S and C—H N intraand intermolecular interactions connect(More)
A triflavanone, Garcineflavanone A (1) and a biflavonol, Garcineflavonol A (2) have been isolated from the stem bark of Garcinia atroviridis (Clusiaceae), collected in Peninsular Malaysia. Their structures were established using one and two-dimensional NMR, UV, IR and mass spectrometry and evaluated in vitro for their acetylcholinesterase (AChE) and(More)
In the title compound, [Fe(2)Zn(C(5)H(5))(2)(C(13)H(11)N(3)S)(2)]·H(2)O, the Zn(II) ion is in a distorted tetra-hedral geometry being coordinated by two thio-semicarbazone ligands via N and S atoms. One of the Cp rings is disordered over two positions with occupancies of 0.55 and 0.45. The dihedral angle between the substituted Cp rings is 56.1 (5)° and the(More)
