Isolation and Identification of Diacylglyceryl-O-4′-(N,N,N-trimethyl)-homoserine from the FernAdiantum capillus-venerisL.

摘要

Diacylglyceryl-O-4′-(N,N,N-trimethyl)-homoserine was isolated from fronds of the fernAdiantum capillus-venerisL. and identified by chemical and spectral analyses. Positional analysis of the fatty acids by lipase treatment showed that palmitic acid was esterified at position 1, but linoleic, linolenic and arachidonic acids at position 2 of the glycerol moiety of the lipid. Although the trimethylhomoserine lipid has been found in some algal species, this is the first report that it exists in a vascular plan
