Abstract
Five glycosylsterols, one glycosylceramide and two glycosylglycerides were isolated from corn seeds. The main glycolipids were monoglycosylsterol, monoglycosylceramide, monoglycosyldiacyl-glycerol and diglycosyldiacylglycerol in decreasing order.
Glycosylsterols consisted of acylmono-, mono-, di-, tri- and tetraglycosylsterol. The principal classes were the first two, the representative molecular species of which were characterized as 6'-palmitoyl-3-O-glucosyl-sitosterol and 3-O-glucosyl-sitosterol, respectively.
Monoglycosylceramide was separated as sphingoglycolipid. The main molecular species were shown to be 1-O-glucosyl-N-2'-hydroxy-arachidoyl-4, 8-sphingadienine and 1-O-glucosyl-N-2'-hydroxy-lignoceroyl-4-hydroxy-8-sphingenine.
Glycosylglycerides obtained were mono- and diglycosyldiacylglycerol. The principal molecular species were speculated to be 1-oleoyl-2-linoleoyl-3-O-galactosyl-sn-glycerol and 1-linoleoyl-2-linolenoyl-3-O-digalactosyl-sn-glycerol, respectively.
