ABSTRACT

Phytochemical and Proximate analyses of two samples of Aloe vera from variable habitats (highland and lowland) of Sokoto metropolis were accessed. Phytochemical and proximate compositions of highland sample were 8.16mg/100g of Saponin, 3.40mg/100g of Glycoside, 1.80mg/100g of Alkaloid and 2.50mg/100g of Anthraquinone. Proximate constituents’ analysis revealed 6% of Moisture, 10.5% of Ash, 2.5% of Crude lipid, 8.13% of Crude protein, 1% of Crude fibre and 70.57% of Carbohydrate respectively. Sodium (242.5mg/100g), Potassium (3500mg/100g), Calcium (2.35mg/100g), Magnesium (3.7mg/100g) and Phosphorous (3.24mg/100g) in highland, also more concentrated than in lowland sample. More phytochemicals are found in lowland sample than highland sample. Phytochemical constituents of the lowland sample were Saponin, Glycoside, Alkaloid and Anthraquinone at 3.5mg/100g, 1.13mg/100g, 0.89mg/100g and 1.2mg/100g concentrations respectively. Proximate compositions were 11% of Moisture, 9% of Ash, 2% of Crude lipid, 7.38% of Crude protein, 1.5% of Crude fibre and 69.26% of Carbohydrate. Mineral composition of the lowland sample had 202.5mg/100g of Sodium, 4750mg/100g of Potassium, 1.4mg/100g of Calcium, 3.1mg/100g and 3.16mg/100g of Phosphorous. Steroid, Tannin and Volatile oil are the common phytochemicals absent in both samples of the plant.
