Glycosaminoglycans (GAG) were extracted from the connective tissue of the palatal rugae, separated by electrophoresis and compared with the results obtained for the remaining palatal mucosal and gingival connective tissues. The GAG content of the rugae (3.01 mg/g defatted dry weight) was higher than in the remaining palatal mucosa (2.33 mg/g defatted dry weight) or gingiva (1.68 mg/g defatted dry weight). Dermatan sulphate was the predominant GAG in both the palatal rugae (48% of total GAG) and the remaining palatal mucosa (50%) followed by hyaluronic acid (33 and 31% respectively). The results do not support previous histochemical observations in which the rugae appeared to be rich in hyaluronic acid.
从腭皱襞的结缔组织中提取糖胺聚糖（GAG），通过电泳进行分离，并与腭部其余黏膜和牙龈结缔组织的结果进行比较。皱襞的GAG含量（3.01毫克/克脱脂干重）高于腭部其余黏膜（2.33毫克/克脱脂干重）或牙龈（1.68毫克/克脱脂干重）。硫酸皮肤素是腭皱襞（占总GAG的48%）和腭部其余黏膜（50%）中主要的GAG，其次是透明质酸（分别为33%和31%）。这些结果不支持先前的组织化学观察结果，即皱襞似乎富含透明质酸。
