Abstract

The content and composition of lipids in saliva of healthy caries-free squirrel monkeys were investigated. The dialyzed and lyophilized saliva on extraction with chloroform/methanol yielded 8.0 +/- 0.9 mg of lipids/100 ml of saliva. Following fractionation on silicic acid column, 30.9% of lipids were found in the neutral lipid fraction, 58.8% in the glycolipid fraction, and 10.3% in the phospholipid fraction. The neutral lipids exhibited high content of free fatty acids (58.8%) and triglycerides (23.3%), the glycolipids consisted mainly of neutral and sulfated glyceroglucolipids (95%), while the phospholipids were rich in sphingomyelin and phosphatidylcholine. The results show that squirrel monkey saliva, while displaying lipid content similar to that of caries-susceptible humans, contains 50% less lipids than saliva of periodontal disease-prone marmoset.

摘要

对健康无龋松鼠猴唾液中的脂质含量及组成进行了研究。用氯仿/甲醇提取经透析和冻干的唾液，每100毫升唾液产生8.0±0.9毫克脂质。在硅酸柱上进行分级分离后，发现中性脂质部分占脂质的30.9%，糖脂部分占58.8%，磷脂部分占10.3%。中性脂质中游离脂肪酸含量高（58.8%），甘油三酯含量高（23.3%），糖脂主要由中性和硫酸化甘油葡糖脂组成（95%），而磷脂富含鞘磷脂和磷脂酰胆碱。结果表明，松鼠猴唾液虽然脂质含量与易患龋齿的人类相似，但比易患牙周病的狨猴唾液中的脂质少50%。
