“…As a comparison, the oleic acid in the sn-1, 2, and 3 positions of C. japonica L. oil were 66.0%, 93.6% and 94.7%, respectively (Noh and Yoon, 2012). For other high-oleic acid vegetable oils, such as Chufa tuber oil, the major fatty acid composition of the oil was 15.4% palmitic, 65.5% oleic, and 16.2% linoleic, while the major fatty acid composition on its sn-2 position was 75.1% oleic and 23.1% linoleic (Kim et al, 2007). For olive oil, the major fatty acid composition of the oil was 12.1-16.3% palmitic and 74.3-77.5% oleic, while the major fatty acid composition on its sn-2 position was 82.2-88.4% oleic (Vichi et al, 2007).…”

SUMMARY:As a unique woody oil tree, Camellia oleifera Abel originates from southern China and is now being cultivated in central China, such as the southern Henan province. The aim of this work is to determine some physiochemical parameters, fatty acid profile and tocopherol composition of the Camellia oleifera seed oils harvested in southern Henan in the 2016 season. The lipid contents of the kernel are in the range of 28.39-56.94% on dry matter. The acid value (AV), saponification value (SV), iodine value (IV), and refractive index of the oils are in the ranges: 0.22-5.17 mg KOH/g,.91 mg KOH/g, 82.0-87.1 g I 2 /100g, and 1.4667-1.4720 n D ( ) 25 , respectively. The main fatty acids are: palmitic 7.07-9.52%, palmitoleic 0.09-0.22%, stearic 1.45-2.94%, oleic 77.02-84.33%, linoleic 5.19-11.23%, linolenic 0.53-0.70% and arachidic 0.22-0.70%. The sn-2 fatty acid composition is: 84.36-91.33% oleic, 7.14-14.22% linoleic, and 0.89-1.96% others. The tocopherol content is in the range of 39.55-75.94 mg/100g oil, including mainly α-tocopherol (33.98-67.82 mg/100g) and γ-tocopherol (5.57-8.27 mg/100g) when the oils are extracted with hexane; and 14.91-44.36 mg/100g, including mainly α-tocopherol (9.42-37.08 mg/100g) and γ-tocopherol (5.50-7.33 mg/100g) when the oils are extracted by ethyl ether. The physiochemical properties C. oleifera seed oils from southern Henan are similar to those from other districts of China.

La acidez, índice de saponificación, índice de yodo e índice de refracción se encuentran en los rangos: 0.22-5.17 mg KOH/g, mg KOH/g, 82.0-87.1 g I 2 /100g y 1.4667-1.4720 n D ( ) 25 , respectivamente. La composición en ácidos grasos fue: 7.07-9.52% palmítico, 0.09-0.22% palmitoleico, 1.45-2.94% esteárico, 77.02-84.33% oleico, 5.19-11.23% linoleico, 0.53-0.70% linolénico y 0.22-0.70% araquídico. La composición en ácido graso en sn-2: 84,36-91,33% de ácido oleico, 7,14-14,22% de linoleico y 0,89-1,96% de otros. El contenido de tocoferoles está en el rango: 39.55-75.94 mg/100 g, y se componen principalmente de α-tocoferol (33,98-67,82 mg/100 g) y γ-tocoferol (5,57-8,27 mg/100 g) cuando los aceites se extraen con hexano y 14,91-44,36 mg/100 g, formados por α-tocoferol (9,42-37,08 mg/100 g) y γ-tocoferol (5,50-7,33 mg/100 g) en aceites extraídos con éter etílico.

“…Studies have shown that tiger nuts have a high energy nutrient such as glucose oleic acid, starch, fats, sugars and proteins (Kim et al, 2007). They are rich in minerals such as phosphorous, potassium, calcium, magnesium and iron as well as vitamins E and C. Tiger nut milk is suitable for diabetic individuals and also helps in weight control because of its high fiber content (Emple et al,1998).The presence of digestive enzymes like the catalase, lipase and amylase in tiger nuts makes it useful in the treatment of indigestion, constipation, flatulence and diarrhoea.…”

ABSTRACT:Researchers and physicians look forward to effective therapeutic agents possibly from medicinal plants following the ineffectiveness of modern drugs used in the treatment of fatty liver and its related diseases. To this ends, we evaluated the effect of Cyperus esculentus on the liver in experimentally induced hyperlipidemia in rats.Aqueous extract of the plant was administered orally to rats at the doses of 300,400 and 600mg/kg body weight(b.wt) for a period of twenty nine days. Fatty liver was induced by twice intraperitoneal injection of TritonWR-1339 at a dose of 300mg/kg b.wt. to wistar rats . The result shows that administration of triton led to significant (P˂0.05) serum increase in the activities of alanine and aspartate aminotransferases (ALT and AST) of the rats.There was no significant (p˃0.05) change in the activities of serum alkaline phosphatase following the administration of triton.The study also shows that there were significant( p˂0.05) reduction in the serum level of total protein , albumin and globulin and increase in serum level of total and conjugated bilirubin though not statistically significant (p˃0.05) following the administration of triton to rats.The observed effects are suggestive of mild toxicity of the liver by triton and this is further supported by several histopathological manifestations such as hepatocellular degeneration, macrovesicular vacuolation,periportal necrosis, congestion ,severe intimal ulceration and stenosis in the blood vessels . Treatment with the aqueous extract of Cyperus esculentus attenuated both the biochemical effects and histopathological manifestations.In conclusion, the results from the serum liver enzymes biochemical parameters and histopathological analyses suggested the toxicity of triton and also showed the effectiveness of the aqueous extract of Cyperus esculentus in attenuating the liver toxicity .©JASEM https://dx.doi.org/10.4314/jasem.v21i4.7

“…Palm oil was supplied by the Malaysian Palm Oil Board (Kuala Lumpur, Malaysia), and lard was obtained from Lotte Samkang (Seoul, Korea). Camellia oil was purchased from a local market in Seoul, Korea and chufa oil was extracted using the conventional pressing method from earth almond seeds (9).…”

“…Preparation of concentrated reaction substrates, however, increases the processing cost. Camellia oil and chufa oil (also called earth almond oil) are known to contain large amounts of oleic acid and can be used as oleic acid sources, in addition to olive oil (9,10). The objectives of this study were 1) to determine reaction yields of OPO when non-preprocessed natural fats and oils were used, and 2) to compare reaction yields using novel oleic acid sources of camellia oil and chufa oil rather than the conventional source of olive oil.…”

Human milk fat substitutes were synthesized using non-preprocessed natural fats and oils with lipase. Enzymatic interesterification of tripalmitin and oleic acid was carried out in isooctane. The reaction reached equilibrium after 12 h and the reaction conditions were partially optimized as a molar ratio of tripalmitin to oleic acid of 1:5, an initial water content of 0.01 g/L, and a water removal time of 1 h. After interesterification of tripalmitin and oleic acid, the reaction products contained 55.2% 1,3-dioleoyl-2-palmitoyl glycerol (OPO). The OPO yield was 25.2% when commercial palm oil and camellia oil were used as substrates, and the OPO concentration was increased to 53.3% after fractional crystallization of the reaction product.
