Evaluation of the Antioxidant Properties of Carvacrol as a Prospective Replacement for Crude Essential Oils and Synthetic Antioxidants in Food Storage.

The phenolic structural analogues of synthetic antioxidants such as butylated hydroxytoluene (BHT) in essential oils have been reported to exhibit antioxidant properties. Additionally, their lipophilicity makes them suitable for use in lipid-rich foods. This study evaluated the antioxidant capacity of carvacrol, a monoterpenoid antioxidant compound in the (Gaertn.

Evaluation of the mineral composition, phytochemical and proximate constituents of three culinary spices in Nigeria: a comparative study.

Spices are prolific sources of phytochemicals of pharmaceutical and nutritional importance. They have been employed for centuries in the treatment of various maladies, in cuisines, and as inhibitors of oxidative degradation in foods. On this premise, a comparative assessment of the quantitative mineral composition, phytochemical and proximate constituents of Xylopia aethiopica (fruits), Piper guineense (seeds), and Rhaphiostylis beninensis (roots) was done using standard protocols.

Methanol leaf extract of Paullinia pinnata exerts sleep-enhancing and anticonvulsant effects via a mechanism involving the GABAergic pathway.

Purpose: Leaf extracts of Paullinia pinnata L. (Sapindaceae) are used in ethnomedicine for the treatment of central nervous system-related diseases such as insomnia and epilepsy. We determined the bioactive constituents, sleep-enhancing and anti-convulsant potentials, and possible mechanisms of action of P.

Protective effect of (Shumach) Didr leaf extract and its fractions against cadmium-induced nephrotoxicity in male Wistar rats.

Cadmium (Cd) is a known nephro-toxicant. This research determined the ameliorative effects of crude methanol extract (Me70) and its fractions on Cd-induced nephrotoxicity in Wistar rats. Male rats were randomly allocated to nine (9) groups of six (6) rats each.

Evaluation of the antioxidant activity of root extract of pepper fruit (Dennetia tripetala), and it's potential for the inhibition of lipid peroxidation.

Background: The antioxidant properties of ethanolic root extract of pepper fruit (Donnetia tripetala), and its effect on lipid peroxidation of some fresh beef tissues during frozen storage were investigated.

Materials And Methods: The antioxidant parameters were assessed using standard methods, while malondialdehyde levels of different fresh beef tissue sections treated with the extract prior to freezing, were estimated in a colorimetric reaction with thiobarbituric acid.

Results: The H2O2-scavenging ability of the extract was similar to that of ascorbic acid, with a maximum scavenging power of 55.
