Phytochemical investigations of leaf, fruit and root bark of Olax manni Oliv. Olacaceae

Abstract

Phytochemical examination of the petroleum ether and methanol crude extracts of the leaf, fruit and root bark of the

Olax manni showed the presence of coumarins, steroid/triterpenes, saponins, fatty acids and tannins and absence of alkaloids in the plant. Volatile oils and flavonoids are present only in the fruit and leaf part of the plant. The petroleum extract of the leaf Olax manni Oliv. (Olacaceae) afforded a colourless crystals (E)-3-methyl-5-phenyl-2-pentenoic acid (Ca,₁₂H₁₄O₂, m.p. 57-58 ^oC), which was identified by C H and spectral analysis (UV, IR, NMR, EIMS).
