“…The high value of peroxide value of C. mannii oil shows that it is more unstable than the two other cucurbit seed oils. These values are lower than values for groundnut oil (20.0 meq O 2 /kg of oil) reported by Onyeike and Ancheru (2002) and for Astorcarpus heterphyllus seed oil (15.0 meq/kg of oil) reported by Ajayi (2008). Tan et al (2002) reported the peroxide values of some edible oils: canola oil (6.68 meq O 2 /kg of oil), olive oil (8.50 meq O 2 /kg of oil), refined-bleacheddeodorized palm plein (0.82 meq O 2 /kg of oil) and sunflower oil (9.10 meq O 2 /kg of oil).…”

Three indigenous cucurbit seeds from Ivory Coast namely Cucumeropsis mannii Naudin, Citrullus lanatus var. Citroides (Thrumb.) Matsum & Nakai and Cucumis melo var. Agrestis were investigated for the physicochemical properties. Thermal properties of their crude oils extracted by a cold solvent method were also tested. Physicochemical characterization of the seeds showed that they are important sources of proteins, lipids, carbohydrates and mineral elements. C. lanatus seeds had the highest lipid content (46.40%) followed by C. melo seeds (36.50%) and C. mannii seeds (35.70%) on dry weigh bases. Most of the index values and chemical characteristics of extracted seed oils are not significantly different, except for the peroxide value and the color parameters of C. mannii. Linoleic acid, whose values ranged from 54.84% to 70.76%, was the major fatty acid out of all seed oil species. The thermal properties revealed that C. melo seed oil had low transition temperatures followed by C. lanatus seed oil and C. mannii seed oil depending on their fatty acid compositions. These results suggest that these thermal properties could be used in the industrial fractionation and the cucurbit seed oils may be used as edible oils due to their similarity to the commonly used edible oils.

“…Ajayi (2008) also found that the seeds were good sources of mineral elements. The result revealed potassium to be the prevalent mineral elements which are 2470.00 ppm and 1680.00 ppm for A. heterophyllus and T. africana, respectively followed by sodium, magnesium and then calcium [4].…”

“…Kranner and Colville (2011) had been investigated the transport of metals to developing seeds, the tissue-specific localization of metals within seeds, and finally the uptake of metals from soil by intact seeds [9]. Ajayi (2008) also found that the seeds were good sources of mineral elements. The result revealed potassium to be the prevalent mineral elements which are 2470.00 ppm and 1680.00 ppm for A. heterophyllus and T. africana, respectively followed by sodium, magnesium and then calcium [4].…”

“…Recent studies have shown that some of the seeds could find application as animal feeds, based on their nutritional values, and raw materials for paint formulation based on the amounts and nature of the oils contained in them [2,[4][5][6][7]. In the study made by Bakoglu et al, nine elements (Cu, Mn, Cr, Ni, Zn, Fe, Mg, Al and Pb) were detected and protein contents were determined between 18.40 -45.54 percentages in the seed.…”

In this study, samples (clover, oats, bean, green lentil, spinach, corn, red lentil and rice) taken from some seeds consumed as food by people and from plant seeds used as provender are examined. Element analysis (Al, B, Ba, Bi, Ca, Cd, Co, Cr, Cu, Fe, K, La, Mg, Mn, Na, Ni, Pb, Sn, Sr, Sb, Si, Ti, U, Zn and Zr) in these samples was measured by using ICP-OES. Ca, K and Mg as major elements in all samples are determined. As results of the element analysis, meaningful relations between the elements in seeds have been researched by making statistical comparisons using one way analysis of variance (ANOVA).

Objective: The current study assesses the fibrinogen and fibrin clot hydrolyzing activities of aqueous seed extract of Jackfruit (AqSEJ). Methods: The protein banding pattern of AqSEJ (100 μg) was analyzed on SDS-PAGE. The proteolytic activity of AqSEJ was confirmed by spectrophotometer and zymography experiments. Fibrinogen, fibrin and plasma protein hydrolyzing activities of AqSEJ were analyzed on SDS-PAGE under reduced conditions. Plasminogen activation and indirect hemolytic activities was analyzed using spectrophotometer. The non-toxic property of AqSEJ was tested by edema, hemorrhage in experimental mice. Results: AqSEJ exhibited proteolytic activity and the specific activity was found to be 1.04 units/mg/min. Furthermore, AqSEJ non-specifically hydrolyzed Aα, followed by Bβ and γ chains of human fibrinogen and specifically hydrolyzed α polymer and α chain of partially cross linked human fibrin clot without affecting β chain and γ-γ dimer even up to the tested dose of 30 μg for the incubation period of 8 hours. Importantly, AqSEJ did not hydrolyze other plasma proteins and devoid of plasminogen activation property. The proteolytic activity of AqSEJ was completely neutralized by PMSF and IAA, while EDTA, EGTA, 1,10-Phenanthroline did not, suggesting the presence of serine and cysteine family proteases. Moreover, AqSEJ did not cause edema and hemorrhage in experimental mice up to the tested dose of 200 μg and non-toxic to RBC cells. Conclusion: AqSEJ hydrolyzes fibrinogen and fibrin clot and non-toxic in nature. Hence, this work showcases the potential applications of Jack fruit seed proteases in the treatment of thrombotic disorders.
