摘要

Abstract

<正> The lipopolysaccharide （LPS

endotoxin） isolated from Bacteriodes fragilis NCTC 9343 ex-hibted an endogenous heterogencity consisting of R （rough） and SR （semi-rough ） LPS fractionsupon sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The LPS was chemically consti-tuted by D-glucosamine

D-glucose. L-rhamnose

D-galactose. fatty acids and phosphate in amolar ratio of 2: 1: 1: 4: 5. 4.: 2.7 The fatty acids were predominated by 3-hydroxypentadecanoic（3-OH-15: 0）

3-hydroxyhcxadecanoic （3-OH-16: 0）

3-hydroxyheptadecanoic （3-OH-17: 0）

3-hydroxy-15-methyl hexadecanoic （3-OH-15-Me-16: 0） and 13-methyl-letradecanoic acid （13-Mc-14:0）. Approximately 1 mol of 2-Keto-3-deoxy-D-mannooctonatc （KDO） was detected after treat-ment of LPS with 48% of hydrofluoric acid （HF）

indicating it was present as a phosphorylatedmolecule.
