“…It can be seen that 63.49% weight contains monounsaturated fatty acids (with one double bond) followed by 33.16% weight of saturated fatty acids (with no double bond) and only 0.73% contains polyunsaturated fatty acids (with more than two double bond). Also as shown in Table 2, the fatty acid profiles reported by Rozentsvet et al [27] for leaves and sorus of S. natans that consists of C14:0, C14:1, C16:0, C16:1, C18:1, C18:0, C20:1, C20:4, C22:0 are comparable with those of S. molesta. In another study, Brouwer et al [28] reported the fatty acids profiles of Azolla filiculoides showed dominations of C16:0, C18:2 and C18:3 whereas in S. molesta with C16:0, C16:1 and C18:1.…”

Biodiesel is considered as one of the promising alternative fuels for diesel engines due its renewability and environment friendly nature. As the process of lipid extraction from the biomass consumes about 90% of the total energy spent for biodiesel production, an efficient and economic method is very important. The amount of lipid extracted from the biomass could be increased if it is pre-treated before the extraction process. Thiswork was an attempt to compare the various pre-treatment methods before extracting lipids from dried Salvinia molesta (aquatic weed), such as autoclaving, microwaving, ultrasonication, sand, and glass grinding. After each pre-treatment method, Bligh and Dyer’s method was used to measure the total lipid content in percentage dry weight (% dwt), which was then compared with the untreated S. molesta. It was foundexperimentally that the lipid yield was 19.97% dwt for ultrasonication > 16.60% dwt for microwaving > 16.46% dwt for glass grinding >16.26% dwt for sand grindin, > 15.72% dwt for autoclaving > 15.36% dwt for untreated. The one-way ANOVA with Tukey’s test was then used to validate the experimental results and showed that ultrasonication method of pre-treatment was the most efficient and had resulted in the highest lipid yieldamong all the methods used which was followed by the microwaving method. The Taguchi method with L9 orthogonal array was then used for the optimization of ultrasonic assisted pre-treatment method before extracting lipid from S. molesta and showed a maximum lipid of 20.86% using 100% amplitude and sonication time of 15 min. The fatty acid methyl ester (FAME) of S. molesta lipid was analyzed using gas chromatographymass spectroscopy (GCMS) with flame ionization detector. It showed fatty acids such as C14:0, C14:1, C16:0, C16:1, C18:0, C18:1, C20:1, C20:4, C22:0 which contributed 97.38% weight of the total fatty acids. FAME consisted of 63.59% monounsaturated, 33.18% saturated and 0.73% polyunsaturated fatty acids in % weight. The physical properties such as specific gravity, kinematic viscosity, cetane number, flash point, cloud point, pour point, saponification value and iodine value of S. molesta biodiesel, which were estimated based on fatty acid profiles are comparable with ASTM 6751-08 biodiesel standard.

“…Salvinia natans is a free floating, rootless aquatic fern and belongs to the family Salvinaceae. Ferns of the genus Salvinia comprise of ten species; majority of which grow in freshwater bodies of tropical and subtropical regions, mainly in Africa and South America [ 2 ]. Salvinia varieties have small hairs on their leaves, making them water resistant.…”

Protective efficacy of natansnin, a dibenzoyl glycoside from Salvinia natans against CCl4 induced oxidative stress and cellular degeneration in rat liver

BackgroundCarbon tetra chloride (CCl4), an industrial solvent, is a hepatotoxic agent and it is the well established animal model for free radical-induced liver injury. The present investigation was carried out to establish the protective effect of natansnin, a novel dibenzoyl glycoside from Salvinia natans against CCl4 induced oxidative stress and cellular degeneration in rat liver.ResultsCCl4 significantly increased the levels of lipid peroxides, oxidized glutathione and decreased the levels of reduced glutathione, SOD and CAT. CCl4 induce marked histopathological changes and increase in the levels of apoptotic proteins. CCl4 treatment significantly increased the levels of apoptotic proteins such as caspases-3, PARP, Bax, Bid and cytochrome C and also increased the levels of inflammatory mediators iNos and Cox-2. Natansnin treatment significantly decreased the levels of CCl4 induced apoptotic proteins and inflammatory mediators. Further natansinin treatment significantly inhibited the CCl4 induced apoptosis which was evident form the reduced TUNEL positive cells.ConclusionsIn conclusion, our study demonstrated the protective effect of natansnin against CCl4 induced oxidative stress and cellular degeneration in rat liver tissue. This protective effect of natansnin can be correlated to its direct antioxidant effect.

“…Although S. natans properties and composition were widely investigated, there are few studies on their fatty acid composition. Rozentsvet et al (2005) analyzed fatty acids in S. natans oil using a mixture of solvents, CHCl 3 :CH 3 OH: C 6 H 6 :NH 4 OH (130:60:20:12), and reported the presence of 16:1, 18:1, 20:1 and 18:3 fatty acids [20]. Based on published data, the fatty acid content of Salvinia species depends on the sub-species and culture conditions.…”

The photosynthetic pigments, protein, macro and microelements concentrations, and fatty acids composition of Salvinia natans, a free-floating aquatic plant, were analyzed after exposure to Hoagland nutrient solution containing 1, 3, and 5 mg/L Li. The Li content of Salvinia natans grew exponentially with the Li concentration in the Hoagland nutrient solution. The exposure to Li did not induce significant changes in Na, Mg, K, Cu, and Zn content but enhanced the Ba, Cr, Mn, Ni and Mo absorption in Salvinia natans. The most abundant fatty acids determined in oils extracted from Salvinia natans were C16:0, C18:3(n6), C18:2(n6), and C18:3(n3). The photosynthetic pigments did not change significantly after exposure to Li. In contrast, chlorophyll and protein content decreased, whilst monounsaturated and polyunsaturated fatty acids content increased after the exposure to 1 mg/L Li. The results indicated that Salvinia natans exposed to low Li concentrations may be a good source of minerals, omega 6 and omega 3.
