Chemical Composition and Antioxidant Activities of Aframomum sceptrum

O.L. Erukainure, O.V. Oke, F.O. Owolabi and O.S. Adenekan

Abstract:
The seeds of Aframomum sceptrum were studied with the aim to ascertain the chemical properties; phytochemical properties and antioxidant activities of the seeds of Aframomum sceptrum, in order to provide data, either for practical use or for basic research needs. Proximate compositions and phytochemical properties were evaluated using standard procedures, while antioxidant activities were evaluated using in vitro assays which utilized the DPPH scavenging method and the ability of the sample extract to reduce FeCl3 solution (reducing power). Statistical significance was established using One-Way Analysis of Variance (ANOVA). Proximate analysis showed a high percentage of crude fibre and crude protein contents, NFE had a higher percent, with Dry matter having the highest percent. Phytochemical screening of the spice showed the presence of alkaloids, flavonoids, phenols, tannins and saponins. A significant difference (p<0.05) was observed between the reducing ability of the spice ethanolic extract and gallic acid with the highest reducing ability observed at the highest concentration of the extract. There was a significant difference (p<0.05) between the scavenging ability of the spice ethanolic extract and gallic acid with the highest scavenging activity observed at the highest concentration of the extract. The presence of bioactive compounds is an affirmation of the use of this spice in the management of various ailments. The total phenolic and flavonoids contents may be responsible for its high antioxidant activity. Consumption of this spice can therefore act as primary and/or secondary antioxidants.
