The oils extracted from two varieties of each of Capsicum annum and Capsicum frutescens were used for this study. The result obtained for physicochemical properties was refractive index (1.451-1.439); specific gravity (0.830-0.751g/cm3); acid value (2.693-0.785mg/g) free fatty acid (1.353-0.395mg/g); iodine value (27.920-22.842mg/g), saponification number (187.935-117.810 mg/g) and unsaponifiable matter (2.400-1.473%). The mineral composition (ppm) result ranged as Na (3.40-2.10); K (98.80-43.70); Ca (32.00-6.00); Mg (13.20-6.00); Zn (0.04-0.01); Fe (7.10-2.65); Cu (1.05-0.16); Mn (0.44-0.12). Cadmium was detected only in bird eye chilli variety of Capsicum frutescens and Nickel was detected in bird pepper variety of Capsicum frutescens. This study has shown that Capsicum annum and Capsicum frutescens are oil sources with edibility and nutritional qualities as well as industrial applications.

Many seeds which we considered as waste and simply discard after taking the juicy part of the fruit may however be reservoir of many nutrients. The seeds of Citrullus lanatus (Watermelon) and Annona muricata (Soursop) were collected, dried and dehulled. They were thereafter pulverized and subjected to analysis to assess their nutritional qualities by identifying their essential amino acids and fatty acids. Results of the proximate analysis revealed that the seeds are rich sources of protein and fat. They also contain all the essential amino acids with leucine being predominant in watermelon and lysine in soursop. The seeds also conta...

The results of the investigation showed the presence of moisture to be 2.86±0.02%, ash- 14.22±0.02%, crude fibre- 16.37 ±0.16%, crude fat- 7.39±0.19%; crude protein- 14.7±0.03%, carbohydrate- 44.31±0.16% and energy- 1276±10%. Mineral elements determined were sodium- 269.40±0.02mg/100g, potassium- 2030.02±0.03 mg/100g, calcium- 616.00±0.10 mg/100g, magnesium- 2.00±0.02 mg/100g, manganese- 2.00±0.02 mg/100g, copper- 0.03±0.10 mg/100g, iron- 20.60±0.20 mg/100g, zinc- 2.74±0.01 mg/100g, chromium- 0.06±0.10 mg/100g, lead- 0.07 mg/100g. The phytochemical screening of chaya leaves (Cnidoscolous aconitifolius) revealed the presence of saponin, tannin, phlobatanin, alkaloid, phytate, phenol, cardiac glycoside and terpenoid. But flavonoid and anthraquinone were not detected. Pearson correlation using Number Cruncher Statistical Package revea...
