A complex polysaccharide originating from grape was purified from a red wine by size-exclusion and ion-exchange chromatography. This polysaccharide contained 2-O-methylfucose, rhamnose, fucose, 2-O-methylxylose, arabinose, apiose, galactose, galacturonic and glucuronic acids, and thiobarbituric acid

โฆ Synopsis
Two minor phospholipid components were isolated from a lipid extract of pig lungs. One was identified as phosphatidylglycerol. The results of alkaline hydrolysis, periodate oxidation and acetolysis showed that the other was a structural isomer of phosphatidylglycerol with the structure of a lyso-bis-phosphatidic acid. Its chromatographic characteristics on thin-layer plates of silica gel and on silicic acid-impregnated paper were quite distinct from those of phosphatidylglycerol. Both of these phospholipids were also present in lipid extracts of rat lungs and rabbit lungs.
