TOTAL TANNIN, TOTAL SAPONIN AND TOTAL ALKALOID CONTENT OF DRIED SESAME (Sesamum indicum) SEEDS

Sesamum indicum L. (Pedaliaceae), commonly known as sesame, is one of the world’s oldest oilseed crops, valued for its high oil content (40–60%) and diverse medicinal applications. Beyond its culinary importance, sesame possesses a wide array of secondary metabolites that contribute to its pharmacological and nutritional properties. This study focused on the qualitative and quantitative determination of total tannin, saponin, and alkaloid contents in sesame seeds to evaluate their phytochemical potential. Dried sesame seeds were procured from a local market in Edo State, Nigeria, and processed
following standard phytochemical procedures. The qualitative screening confirmed the presence of tannins, saponins, and alkaloids, while quantitative evaluation revealed that tannins were the most abundant phytochemical (21.27 + 0.35 g TAE/kg), followed by saponins (20.08 ± 0.33g DE/kg) and alkaloids (9.10 ± 0.49 %). The presence of these bioactive compounds indicates that sesame seeds possess strong antioxidant
and therapeutic potential. Tannins contribute to antioxidant and antimicrobial activities, saponins play a role in cholesterol regulation and immune modulation, while alkaloids are associated with analgesic and anti-inflammatory effects. The findings support the traditional use of sesame in herbal medicine and suggest its further application in nutraceutical, pharmaceutical, and cosmetic industries.
