Abstract Three epimeric phenylpropanoid glycosides have been isolated from the aqueous acetone extract of Paulownia coreana inner bark. One compound is new and its structure has been established by spectroscopic methods as R,S-7″′-(3″′,4″′-dihydroxyphenyl)-ethyl-O-α-L-rhamnopyranosyl(1″→3′)-β-D-(6′-O-caffeoyl)-glucopyranoside.

Two new phenolic compounds, 2,4,6-trihydroxy-5-methyl-acetophenone 2- O-β-D-glucopyranoside (3), and benzyl alcohol 7- O-(3’,4’,6’-tri- O-galloyl)-β-D-glucopyranoside (8), together with eight known phenolic compounds, were isolated from the 70% aqueous acetone extract of Eucalyptus gomphocephala DC. (Myrtaceae). The isolated compounds were elucidated based on their 1H, 13C, DQF-COSY, selective 1D-TOCSY, HSQC, and HMBC NMR spectroscopic; and ESIMS data. The antioxidant effect of the phenolic compounds was tested using 1,1-diphenyl-2-picrylhydrazyl (DPPH.), hydroxyl radical and super oxide anion radical scavenging assays. The cytotoxicity of the isolated compounds was evaluated using HeLa cell line.

From the aqueous acetone extract of the leaves of Psidium guajava L. the flavanols catechin and gallocatechin, the procyanidins B1, B2, B3 and two prodelphinidins (gallocatechin - (4α→8) - catechin; gallocatechin - (4α→8) - gallo-catechin) were isolated. A more abundant proanthocyanidin polymer was also isolated, purified and its chemical constitution studied by 13C-NMR and phloroglucinol degradation. The mean molecular weight of the polymer was estimated to be about 9 to 10 flavan-3-ol-units with a ratio of procyanidin: prodelphinidin units at 2 : 1 some of which are derivatized by gallic acid.

Abstract Procedures from 2 methods, one for aflatoxins B1 and M1 in eggs and one for aflatoxicol in milk, blood, and liver, have been combined to determine the 3 toxins in eggs. The sample is blended with sodium chloride-saturated water and this mixture is then blended with acetone. After separation from the solid residue, the aqueous acetone extract is defatted with petroleum ether. The toxins are next partitioned into chloroform and separated from interferences on a silica gel column. Aflatoxicol is determined by fluorescence measurement after separation on a C18 reverse phase liquid chromatographic column, and aflatoxins B1 and M1 are determined by fluorescence densitometry after separation on a silica gel thin layer chromatographic plate. In a recovery study with eggs, mean recoveries of aflatoxicol added at levels of 0.1, 0.05, and 0.025 ng/g were 87, 77, and 78%, respectively. Mean recoveries of aflatoxins B1 and M1 added at a level of 0.1 ng/g were 75 and 87%, respectively, and at an added level of 0.05 ng/g were 86 and 75%. The within-laboratory precision (repeatability) ranged from 2 to 13%.

The metabolism of carbaryl has been studied in the engorged adult female cattle tick, B. microplus using 14C�labelled compounds. Forty-eight hours after injection of [carbonyl-14C]carbaryl only 6% of the radioactivity could be recovered in an aqueous acetone extract while 90% was recoverable after an equivalent injection of [1-14C]carbaryl. Hydrolysis of the carbamate ester, hydroxylation, and conjugation were the major metabolic pathways. The radioactivity of the extract was completely accounted for as I-naphthol (55%) and 1,5-dihydroxynaphthalene (45%) after acid hydrolysis. 1,4-Dihydroxynaphthalene appears to be absent. Evidence was also obtained for some hydroxylation of the N-methyl group. No unchanged carbaryl could be detected.

This study investigated the nutraceutical potential of ripe and unripe plantain fruit peels which are commonly discarded as food wastes. Proximate and mineral analyses of the samples were performed as per the standard methods of the Association of Official Analytical Chemists. Preliminary phytochemical screening of aqueous, acetone and methanol extracts of the peels was also carried out in accordance to standard methods. From the results of the study, acetone extract of the unripe peel showed the presence of eight phytochemicals while its ripe peel showed the presence of four. Aqueous and ethanol extracts of both peels showed the presence of same phytochemicals i.e., terpenoids, cardiac glycosides, phenols, flavonoids, alkaloids, reducing sugars and saponins. Meanwhile, tannins was absent in all three solvent extracts of both peels. Fat, ash, crude fibre and carbohydrate contents of the unripe peel were higher than those of the ripe. However, moisture and protein contents of the ripe peel were significantly higher (P < 0.05) than those of the unripe. Of all the nine essential minerals assayed (K, Na, Mg, Ca, P, Fe, Zn, Mn, Cu), concentrations of all except calcium were significantly higher (P < 0.05) in the unripe peel than those of the ripe peel. Notably, none of the heavy metals (Co, Cr, Cd, Pb, Ni) assayed was detected in both samples. This study concludes that ripe and unripe plantain fruit peels could serve as promising sources of nutrients and bioactive compounds essential for the health of both livestock and humans.
