Physical properties, chemical composition, and nutritional quality potentials of the seeds of Lonchocarpus sericeus (cube root) were investigated. The water absorption properties of the seeds were measured both gravimetrically as hydration capacity (0.02±0.005 g/seed), and hydration index (0.06±0.01) and volumetrically as swelling capacity (0.01±0.00 mL/seed) and the swelling index   (1.2x10-4±0.00). A 100 g of seeds contained 17.53±2.08, 38.83±4.16, 3.18±0.19, 24.93±3.21, 29.96±3.82, and 3.10±0.89 g moisture, crude fiber, ash, crude fat, crude protein, and nitrogen-free extract (NFE), respectively; Further, the sample had per 100 g 149.20±0.24 kJ gross energy, 848±16.1, 722±10.0, 720±9.1, 230±8.2, and 224±8.1 mg Fe, Mn, Zn, Cu, and Na, respectively. The seed also contained 3.14±0.12, 2.18±0.32 and 4.30±0.06 mg/g tannin, oxalate, and saponin, respectively. The essential-to-total amino acid ratio (E/T, %) was 44.10 %; the average predicted protein efficiency ratio (PER) was 2.70, while the predicted biological value (BV) was 34.85. Elaidic acid was the most significant fatty acid (46.32 %) found in the seeds with a total saturated and unsaturated fatty acids of 46.14 and 50.50 %, respectively. The oil of L. sericeus was equally rich in bioactive compounds, including tocopherols, sterols, phospholipids, tocotrienols, and terpenoids with a concentration of 50.09, 479.13, 333.14, 1.34, and 3.33 x 10-4 mg/100g, respectively. L. sericeus seed can be a potential source of dietary energy, industrial oil, bioactive compounds, and vegetable protein.

This study characterized the bioactive components in the seed oil of <i>Pentaclethra macrophylla</i> to establish its usefulness in replacing costly convectional oils in industrial applications. Identification and quantification of the bioactive attributes were performed using gas-liquid chromatography with flame ionization detector (GC-FID) after extraction with n-Hexane. The main bioactive contents per 100 g in the oil were sitosterol (457.58 mg), campesterol (34.54 mg) and stigma-sterol (18.52 mg) been the most abundant sterols. The oil contained per 100 g β-carotene (15.89 mg), xanthophyll (10.32 mg), lutein (9.22 mg), and neo-xanthin (5.46 mg) as the highest carotenoids. The oil has ɣ- tocopherol (43.83 mg) and α-tocopherol (3.35 mg) also per 100 g. The main terpenes per 100 g in the oil were γ-elemene (17.28 mg), α-caryophyllene (13.06 mg), β-elemene (12.43 mg) and D-limonene (6.11 mg). Terpenoids including β-amyrin, α-amyrin and lupeol were found in trace amounts.
