“…2.2). On the other hand, the isomerization of methyl linoleate over heterogeneous catalysts has been reported earlier, and the catalysts applied were rhodium and ruthenium on activated carbon [32,33], as well as bimetallic supported ruthenium nickel catalysts [34].…”

Wood is a valuable raw material for the production of fine chemicals. However, since wood extractives cannot be used directly, their chemical transformation is required. Catalytic processes, in particular, possess the advantages of being environmentally friendly and industrially attractive. The use of sugars for the production of sugar alcohols and terpene transformations, are well known examples. In contrast, catalytic processes for the utilization of fatty acids, phytosterols and lignans as raw materials are very rarely reported. The products obtained from these materials exhibit health promoting properties. The present mini-review is focused on recent activities devoted to catalytic transformations of fatty acids, phytosterols and lignans derived from wood.

“…For better selectivity, always non-polar solvents were used and high solvent/reactant ratio is preferred to avoid polymerization reaction. In case of hydrogenation, highly protect solvents such as methanol and isopropyl alcohol were used, which exhibits high activity and selectivity [62]. In CLA synthesis, isomeriation and hydrogenation are two competing identical reactions.…”

Dietary fatty acids are highly recognized as an important biologic controller and having potential to provide number of health benefits. Conjugated linoleic acid is an important conjugated fatty acid with a mixture of positional and geometric isomers of linoleic acid (C18:2, n-6).In the last three decades, this particular type of PUFA has gained significant attention for their biologically active properties and health effects. CLA can be synthesized endogenously in tissues and partial bio hydrogenation of unsaturated fatty acids in rumen stomach. Also, it can be synthesized by using microbial strains like Lactobacillus spp and Butyrivibrio fibrislovens but the amount of yield obtained is not satisfactory. Application of homogenous and heterogeneous catalysts and photoisomerization methods increased the conversion of linoleic acid to CLA. In 2008, CLA got generally recognized as safe (GRAS) status by FDA, which increased the consumption of CLA and used as a nutraceutical in dietary supplements/foods. With the increasing market demand, the research should focus in developing innovative synthesis methods with enhanced productivity of specific CLA isomers. The main scope of this review is to outline the current knowledge on different types of synthesis of CLA isomers and sources rich in CLA.

“…Sitosterol, a triterpenoid, is the raw material for a cholesterol-suppressing agent, sitostanol (Ekblom, 2005;Michalson and Devore, 2004). Conjugated fatty acids (conjugated linoleic acid), which are important antioxidants, can be produced by isomerization of fatty acids and fatty acid esters with homogeneous (DeJarlais and Gast, 1971;Frankel, 1970;Mukesh et al, 1988) or heterogeneous catalysts (Bernas et al, 2002a(Bernas et al, , 2002b. Fatty acids and resin acids can also be saturated through catalytic hydrogenation and used as fuel components after decarboxylation over heterogeneous catalysts, such as supported Pd Snåre et al, 2006).…”
