“…Bukar et al (2010) and Suarez et al (2003) identified, the presence of a short polypeptide named 4 (α-Lrhamnosyloxy) benzyl-isothiocyanate in moringa seeds. The peptide might act directly on microorganisms and might result in growth inhibition by destroying the cell membrane (Abalaka et al, 2012 Asokkumar et al (2009). This is in accordance with previous discovery that suggested the flavonoids carry antioxidant activity through scavenging or chelating have deterrent role in cancer and heart disease (Middleton et al, 2000).…”

Abstract:The effect of three different extraction methods, namely supercritical CO 2 , soxhlet and solvent methods on the yield, efficiency, physico-chemical properties, nutritional, anti-nutritional composition, antimicrobial and antioxidant activities of moringa (Moringa oleifera Lam.) seed kernel oil was investigated in this study. Oil extraction for SC-CO 2 were 37.76 g/100g and 98.43%, observed to be higher than those of soxhlet extraction (29.12 g/100g and 76.29%), and significantly lower than solvent extraction (22.12 g/100g and 57.99%). The physico-chemical composition of the oils showed considerable variation among the extraction methods. The SC-CO 2 extracted oil was found to be of superior quality, showing negligible thermal degradation and exhibited significantly (p<0.01) higher nutritional and antioxidant activity and lower anti-nutritional composition than the soxhlet and solvent extracted oils. Oils produced by SC-CO 2 and soxhlet extraction methods had antimicrobial activities higher than solvent extracted oil. SC-CO 2 extracted oil was found to have maximum number of bioactive compounds (14 compounds) followed by solvent (8 compounds) and soxhlet (4 compounds) extracted oil. The results of the study demonstrated that SC-CO 2 would be a promising process for the extraction of moringa seed kernel oil of premium quality.

“…In the present study, ginger and turmeric water extract combination reduced serum cholesterol level. These results are in agreement with [43] and [9] who reported that ginger acts as a hypolipidemic agent in cholesterol fed rabbits. Also, [18] observed that cholesterol synthesis was inhibited by some ginger extract derived metabolite, or by secondary mediator.…”

“…Moreover, the antioxidant potential of Ceiba pentandra seed oil was further highlighted by the quenching of DPPH free radicals, which is a proton free radical commonly used to determine the free radical scavenging power of antioxidants [24]. The decrease in absorbance of DPPH-oil mixture in this study, which measured the extent of radical scavenging potential of the oils supported the findings of [25]. In addition, reducing power of a compound is related to electron transfer ability of the compound which could lead to the neutralization of free radical [26].…”

IntroductionFree radicals are generated in our body during the normal metabolic processes and during exposure to adverse pathophysiological conditions [1]. They are unstable species that are able to induce cellular damage in several ways. The most deleterious effects of free radicals is damage to DNA [2], which is associated with the process of carcinogenesis. Phytochemicals such as phenolics, carotenoids and dietary fibers are gaining increased attention because of their antioxidant, anticarcinogenic, antimutagenic, and other health promoting properties [3]. Although synthetic antioxidants such as butylated hydroxy toluene, butylated hydroxy anisole, gallic acid esters and tertiary butylated hydroquinone have potential to neutralize free radicals, they have been criticized due to possible toxic effects, low solubility along with moderate antioxidant activity. Hence there arises a need to discover new potential natural sources of antioxidants.Several studies have successfully correlated the phenolic content with antioxidant activity. For example, natural phytochemicals present in berry crops, tea, oilseeds, beans, fruits and vegetables, herbs and spices such as rosemary, thyme, sage, nutmeg, turmeric, white pepper, chili pepper, ginger and several medicinal plants are good source of antioxidant activity [4] and this antioxidant activity have been correlated to the plant secondary metabolites such as flavonoids, carotenoids, alkaloids, tannins and phenolic compounds.Many fruits have inedible seeds and are not part of human diet.However, such seeds are a part of ayurvedic preparations against many diseases. Further, since seeds are the primary stage of plant life cycle, they have strong defence mechanism possibly due to the presence of phytoconstituents contributing to antioxidant activity [5]. Seeds are the primary stage of plant life cycle, they have strong defence mechanism possibly due to the presence of phytoconstituents contributing to antioxidant activity. In the present study, the oil of Ceiba pentandra seeds (belonging to order Malvalea and the family Malvaceae; commonly known Kapok) was evaluated for their phytochemical constituents and antioxidant activity. Materials and Methods ChemicalsChemicals and reagents used for antioxidant estimations were purchased from Merck. All additional chemicals used were analytical grade. Altogether the experiments were performed at room temperature unless otherwise stated. AbstractBackground: Ceiba pentandra seeds belonging to order Malvalea and the family Malvaceae, commonly known Kapok were evaluated for their phytochemical ingredients and antioxidant activity.
