Characterization of sn-2 alk-1'-enyl ethers of glycerol from rice bran oil.

Ether lipids have biological applications which would dissipated as an important constituent in cell membranes. These are mostly found in animal tissues and rare in plant origin. Alk-1'-enyl ethers are class of ether lipid forming aldehydes on cleavage of ether bonds. The present study enrolled the presence of aldehyde in unsaponifiable matter of rice bran oil (RBO) and hence the identification of source of aldehydes in RBO was conducted. With respect to the earlier reports the investigation turned to major lipid constituents such as triacylglycerols, diacylglycerols etc. Using the column chomatographic method lipid fractions are separated, recolumned, purified and analyzed by spectrochemical methods such as FT-IR, (1)HNMR, (13)CNMR, Mass spectrometry and confirmed the presence of ether lipids. The sn-2 position was confirmed by enzymatic hydrolysis using pancreatic lipase. Moreover the formation of aldehyde from these ether lipids was also confirmed by spectrometric methods.
