Proceeding from the fact that the seeds of Roselle plant are full of nutritional constituents, however in Egypt and Libya, they are often discarded as a by-product, this study aims to evaluate the nutritional composition of Roselle seeds grown in Egypt and Libya as a source of oil and protein besides making a comparison between whole chemical composition of Roselle seeds grown in both countries. Ground of whole Egyptian and Libyan Roselle seeds powder contained high amount of protein (31.02% ± 0.93% and 28.67% ± 0.45%), crude fat (21.6% ± 0.66% and 16.94% ± 0.86%) and total ash (6.89% ± 0.11% and 5.60% ± 0.10%), respectively. However, Egyptian seeds have moisture content, protein, crude fat and total ash higher than Libyan seeds. Crude oil from Egyptian seeds had high refractive index and iodine value in comparison with crude oil from Libyan seeds. There were no remarkable differences between both seeds in acidity percent, unsaponifiable matters percent and saponification value. Linoleic, oleic and palmitic acids were the major fatty acid constituents in Egyptian Roselle seeds. Meanwhile linolenic, linoleic, oleic, stearic, palmitoleic and palmitic acids were the major fatty acid constituents in Libyan Roselle seeds. Crude oil from Egyptian seeds had higher percent of unsaturated fatty acids than crude oil from Libyan seeds. Unsaponifiable matters constituents for extracted oil from Egyptian seeds were free from n-pentacosane (C25) and rich in n-hexacosane (C26). Oil from both seeds had the same content of Beta sito-sterol and stigma-sterol. Both seeds were rich in glutamic acid, aspartic acid, arginine and leucine. Libyan seeds were rich in essential amino acids in comparison with Egyptian seeds. Finally nutritional comparison of Roselle seeds variation depends on the variety, location and environmental conditions during cultivation. Roselle seeds are a good source for extraction of oil and protein. Protein from Roselle seeds could be used as a supplement material for poor food in lysine.

“…As lady's finger seed oil is rich in palmitic and linoleic acids, its TAG profile is dominated by PLL, PLO/POL, and PPL in an almost equal proportion. Since different subspecies of lady's finger seed produce oil with varying fatty acids composition and TAG profile, [71] the TAG composition obtained is thus, slightly different from the values reported by Fiad. [71] Being abundant in eleostearic and stearic acids, bitter gourd seed oil has SEE (where S is stearic acid) as its major TAG.…”

“…[12,69,70] The three most abundant fatty acids in the oil account for 97.8% of total fatty acid which is in agreement with the range (94.8-99%) reported in the literature. [12,39,71] On the other hand, coconut oil is rich in medium chain fatty acids, namely lauric and myristic acids (Table 3), and is more suitable as cooking/frying oil when compared to the other seed oils because it contains a low level (0.7%) of polyunsaturated fatty acids making it less susceptible to oxidative deterioration. Besides, coconut oil also contains a high amount of short and medium chain fatty acids (84.5%) that makes it suitable as feedstock in the production of biodiesel, [72] lubricant, [23] flavor esters, [73] and αamylase.…”

The physico-chemical properties of solvent-extracted oil from the seeds of noni (Morinda citrifolia L.), spinach (Spinacia oleracea L.), lady's finger (Abelmoschus esculentus (L.) Moench), bitter gourd (Momordica charantia L.), mustard (Brassica nigra (L.) Koch), and the dried kernel (copra) of coconut (Cocos nucifera L.) were characterized. Among these sources, spinach seed had the lowest oil content (4.5 ± 0.4%) while coconut kernel had the highest oil content (63.1 ± 2.8%). Palmitic, oleic, and linoleic acids were the major fatty acids for spinach, lady's finger and noni seed oils, while erucic, eleostearic, and lauric acids were the major fatty acids for mustard seed oil, bitter gourd seed oil, and coconut kernel oil, respectively. All of the oils possessed at least three major peaks in their triacylglycerol profiles except for bitter gourd seed oil which had only one major peak (1-stearoyl, 2,3dieleostearoyl). The last endothermic peaks were -12.4, -6.0, 6.8, 57.7, 2.7, and 24.3ºC for noni, spinach, lady's finger, bitter gourd and mustard seed oils, and coconut oil, respectively. Initially, the solid fat content of bitter gourd seed oil decreased gradually, but became rapidly after 50 until 60ºC. Coconut oil had its solid fat content reduced rapidly around 14 to 28ºC.
