520 3 |a Uapaca heudelotii Baill. is well known in various African cultures for its ap-plication in the treatment of infections and inflammatory conditions. This study was focused on providing standard identification parameters for au-thentication and quality assurance of U. heudelotii through morphological observations, screening of phytochemical constituents, fluorescence, spec-troscopic and physicochemical analysis. U. heudelotii leaves are simple, el-liptic and arranged in whorls. The bark is greyish-brown with longitudinal striations on the outer surface and pale red on the inner surface. Leaf lami-na microscopy displayed anticlinal polygonal straight-walled epidermal cells, with anisocytic stomata found only on the abaxial surface. Leaf sur-face constants were determined. Microscopy of powdered leaves and barks revealed the presence of epidermal cells, starch grains, calcium oxalate, sclereids and pitted vessels. Alkaloids, flavonoids, coumarins, saponins, triterpenoids, phytosterols and tannins were identified in both stem bark and leaves. The total phenolic content for the leaf and bark were 219.2 ± 10.013 and 153.9 ± 1.602 mg/g gallic acid equivalent respectively. The total flavonoid contents were recorded as 1036 ± 33.37 and 310.2 ± 79.00 mg/g quercetin equivalent for the leaf and bark respectively. The total ash for the leaf and bark was 6.41 ± 0.208 and 5.01 ± 0.258 respectively. The pH values for the aqueous and alcoholic extracts were slightly acidic (3-5). In ele-mental analysis, lead (Pb) was detected within the acceptable limit (0.0019- 0.0025 mg/kg). In conclusion, the current results have provided standard parameters for the correct identification and quality assessment of U. heu-delotii. © 2022 Horizon e-Publishing Group. All rights reserved.
