The present study examined preliminary bioactive constituents and gas chromatographic FID evaluation of Garcinia kola seeds. Results obtained from the preliminary screening showed that the following phytochemical compounds were present flavonoids, cardiac glycosides, saponins, steroids and reducing sugars. These phytochemicals are known to play important roles in the bioactivity of medicinal plants. Results of the gas chromatographic FID evaluation showed that Garcinia kola contained various amount of phytochemicals. For steroids, sitosterol, campesterol, and Avenasterol had the highest concentration of 1.43 mg/100 g, 0.159 mg/100 g, 0.076 mg/100 g while in saponin, Neochlorogenin, yamogenin, tigogenin had the highest concentration of 6.286 mg/100 g, 0.910 mg/100 g, 0.017 mg/100 g. In Alkaloid lupanine, undulatine, powelline, vocangine had the highest concentration of 192.534 mg/100 g, 166.812 mg/100 g, 124.452 mg, 100 g while Dihydro-oxo- Dimethoxytyramine had the lowest concentration of 2.865 mg/100 g. Linalool, Nerol and Alpha Bergamotene had the highest concentration of 35.213 mg/100 g, 32.154 mg/100 g, 11.787 mg/100 g in Terpenes while terpineol had the lowest concentration of 0.0136 mg/100 g. Salicin and Arbutin has the highest concentration of 83.648 mg/100 g, 2.724 mg/100 g while Digitoxin has the lowest level of 0.0444 mg/100 g in glycosides. Diallythiosulphinate had the highest value of 0.0032 mg/100 g in Allicin while Apigenin was highest 42.439 mg/100 g in Lignan. Beta-crytoxanthin and Xanthophyll had the highest concentration of 436.126 mg/100 g and 314.343 mg/100 g in carotenoid. Findings showed Garcinia kola can be useful in the pharmaceutical and medicinal sciences.
