Abstract

Approximately 70% of the fatty acids recovered after acid or alkaline hydrolysis of the lipopolysaccharide of Rhizobium trifolii were hydroxy fatty acids identified as hydroxymyristic and hydroxypalmitic acids. Palmitic acid was the only saturated fatty acid found in the lipopolysaccharide of R. trifolii. Octadecenoic and a small amount of hexadecenoic acids were also identified. The results of BF(3) methanolysis and hydroxylaminolysis suggest that hydroxypalmitic acid is N-acyl bound.

摘要

经酸或碱水解三叶草根瘤菌脂多糖后回收的脂肪酸中,约70%为羟基脂肪酸,鉴定为羟基肉豆蔻酸和羟基棕榈酸。棕榈酸是在三叶草根瘤菌脂多糖中发现的唯一饱和脂肪酸。还鉴定出了十八碳烯酸和少量十六碳烯酸。硼(3)甲醇解和羟胺解的结果表明羟基棕榈酸是N-酰基结合的。
