Phytochemical and Mineral Properties of Zobo Drink Processed with Miracle Leaf and Wonderful Kola Extract

Abstract

This study investigated the phytochemical and mineral compositions of Zobo drink fortified with varying concentrations of miracle leaf and wonderful kola extracts. A mixture design was used generating five samples. Phytochemicals and mineral analysis were carried out on the samples using standard methods.  Phytochemical analysis revealed significant variations with saponin content ranging from 0.20 to 1.20 mg/g, alkaloid from 0.07 to 1.00 mg/g, flavonoid from 14.10 to 19.59 mgQE/g, phenol from 16.02 to 26.25 mgGAE/g and tannin from 20.95 to 31.30 mg/g. Sample Bsc (60 % Zobo, 8 % miracle leaf extract, and 32 % wonderful kola extract) showed the highest levels of saponin (1.20 mg/g), alkaloid (1.00 mg/g), and tannin (31.30 mg/g), indicating its potential for cholesterol-lowering, immune-boosting, and antioxidant properties. Mineral analysis indicated significant increases in calcium (12.85–62.01 mg/100g), magnesium (38.83–84.79 mg/100g), iron (2.12–3.61 mg/100g), and sodium (10.20–17.45 mg/100g). Sample Bsc- (60% Zobo, 8% miracle leaf extract, and 32% wonderful kola extract), consistently showed the highest concentrations of these minerals, making the fortified drink particularly beneficial for bone health, iron supplementation, and cardiovascular function fortifying Zobo drink with miracle leaf and wonderful kola significantly enhances its nutritional and medicinal properties, offering a functional beverage with improved antioxidant activity, enhanced mineral bioavailability and therapeutic potential.
