Mineral Content, Proximate Composition and the Antioxidant Properties of the Ethanol Extract of Hyphaene thebaica L. from Gezawa Town, Kano State, Nigeria

Abstract

The fruits of the doum palm tree, Hyphaene thebaica are one of the oldest relish fruit. This study analyzed the chemical composition (both proximate and the mineral contents) of this plant, as well as its antioxidant property. The mineral content was determined by atomic absorption spectrophotometry, while the proximate and phytochemical analyses were carried out using standard procedures at Bayero University, Kano. The fruit were found to contain some minerals including K (3366.21 mg/100 g), Ca (292.04 mg/100 g), Na (212.27 mg/100 g), Mg (177.14 mg/100 g), Fe (4.86 mg/100 g), Mn (0.83 mg/100 g), Zn (0.68 mg/100 g), Cu (0.40 mg/100 g), Ni (0.32 mg/100 g) and Co (0.12 mg/100 g). The proximate composition of the doum palm fruit pulp reveals protein (2.86%), lipid (0.92%), ash content (6.24%), crude fiber (12.87%), moisture content (8.64%) and carbohydrate 68.47%. The DPPH radical scavenging efficacy of the ethanol extract of the fruit of the doum palm tree was analyzed at different concentrations of the extract. At concentration 0.0625 mg/mL, 0.125 mg/mL, 0.250 mg/mL and 0.500 mg/mL the extract showed inhibitory activity of 31%, 61%, 72% and 81% respectively. Thus the doum palm fruit pulp extract possess potential antioxidant properties.

Doum Palm Meal (Hyphaene Thebaica) and Partial Maize Substitution: Impact on The Blood Biochemical Indicators of Weaned Pigs

“…Because the sample's crude protein concentration is low (less than 30 %) and it cannot be used to replace protein sources in the diet of monogastric according to [15]. The study's 13.51% crude fiber content was more than the 12.87 % reported by [14]. The experimentally reported ash content is consistent with the results of [17], whereas the reported energy level is consistent with those of [18].…”

“…The doum palm is used to treat bilharziasis and its fruit is sometimes chewed to decrease high blood pressure [12,13]. [14] reported that the doum palm fruit pulp's proximate composition included the following: protein (2.86%), fat (0.92%), ash (6.24%), crude fiber (12.87%), moisture (8.64%), and carbohydrates (68.47%). Similar findings were made by [9] who recorded a crude protein of 2.92 percentage, ether extract (0.49 percentage), crude fiber (15.14 percentage), and metabolizable energy (2254.5 kcal/kg) for DPM.…”

“…The plates were rotated clockwise for easy mix up of the sample and the media and incubated for 3-5 days at 37 °C. Colonies were then counted and recorded after incubation period [26].…”

Effect of Doun Palm Mesocarp Meal (Hyphaene Thebaica) As Partial Replacement for Maize on Growth Performance and Haematological Indices of Weaned Pigs

“…Applying the Statistical Analysis System Software (SAS), all collected data underwent a one-way analysis of variance. The SAS Turkey test was used to separate the means, and significant differences were identified at P˂0.05 [13]. [14,15].…”
