Abstract

The lipid content and composition of marmoset saliva was investigated. Extraction of the dialyzed and lyophilized saliva with chloroform/methanol yielded 15.6 +/- 3.1 mg of lipids/100 ml of saliva. Of the total lipids, 41.7% were represented by neutral lipids, 50.7% by glycolipids and 7.6% by phospholipids. Neutral lipids had a high content of free fatty acids (67.0%), cholesterol and its esters (20.0%) and triglycerides (11.8%). The glycolipid fraction was comprised of simple glycosphingolipids (13.2%), and of neutral and sulfated glyceroglucolipids (86.8%), whereas sphingomyelin, phosphatidylcholine and phosphatidylethanolamine accounted for 63.6% of the total phospholipids. The results indicate that marmoset saliva, in comparison to that of human, contains twice as much of total lipids and exhibits an elevated level of phospholipids, and glycolipids.

摘要

对狨猴唾液的脂质含量和成分进行了研究。用氯仿/甲醇对透析并冻干的唾液进行提取，每100毫升唾液产生15.6±3.1毫克脂质。在总脂质中，中性脂质占41.7%，糖脂占50.7%，磷脂占7.6%。中性脂质中游离脂肪酸含量高（67.0%），胆固醇及其酯类（20.0%）和甘油三酯（11.8%）。糖脂部分由简单糖鞘脂（13.2%）以及中性和硫酸化甘油葡萄糖脂（86.8%）组成，而鞘磷脂、磷脂酰胆碱和磷脂酰乙醇胺占总磷脂的63.6%。结果表明，与人类唾液相比，狨猴唾液中的总脂质含量是人类的两倍，且磷脂和糖脂水平升高。
