摘要
A method has been developed for the quantitative and rapid estimation of sulfolipid and galactolipids in plant tissues. The procedure is based on the isolation of pure glycolipids by a combination of DEAE-cellulose column and thin-layer chromatography. The sugar component is estimated by the reaction of the lipid on the thin-layer adsorbent with phenol and sulfuric acid. Alternatively, the lipid is deacylated on the adsorbent in 2 N sulfuric acid and an aliquot of the hydrolyzate is reacted with phenol and sulfuric acid. Very small amounts of sulfo- and galacto-lipids can be reproducibly estimated by this method. © 1968.
