Chemical composition of kernels from some species of Cucurbitaceae grown in Nigeria.
The seeds of lesser-known species - Cucumeropsis mannii, Lagenaria sicceraria varieties 1 and 2 and Telfairia occidentalis, of Cucurbitaceae family were studied. The protein content of C. mannii was 36.1% and the varieties 1 and 2 of L. sicceraria had 32.1% and 33.3% respectively. Telfairia occidentalis had protein content of 33.2%. The fat contents of C. mannii, L. Sicceraria var. 1 and 2 and T. occidentalis were 44.4%, 44.6%, 46.9% and 42.3% respectively. The crude fibre content for each of the two varieties of L. sicceraria was 3.6% and T. occidentalis had 5.5%. Cucumeropsis mannii had the lowest (2.4%) fibre content. The carbohydrate contents for L. Sicceraria var. 2, C. mannii, and T. occidentalis were 12.6%, 13.2% and 14.4% respectively. Lagenaria sicceraria var. 1 had the highest value of carbohydrate (15.8%). The species were relatively rich in potassium and magnesium with range of values of 0.56% to 0.68% and 434 ppm to 444 ppm respectively. Cucumeropsis mannii and Lagenaria sicceraria var. 2 had relatively high contents of calcium (117 ppm) and iron (109 ppm) respectively. The kernels of these species exhibited lipase activity. Telfairia occidentalis showed the highest degree of lipase activity.
