Six classes of neutral lipids, i.e. triacylglycerol (TG), free fatty acids (FFA), monoester waxes (MW), free- and esterified sterols (FST and SE), and squalene (SQ) were identified by thin layer chromatography of the lipid materials extracted separately from the secretion as well as from the isolated whole glands present in the skin of the floor of the external ear canal of the domestic fowl. Secretory lipids contained considerable proportions of MW fractions (17.03%), TG (22.23%), and SQ (14.66%), while TG was the major component (41.10%) in the lipids from the isolated glands. Polar lipids, which comprised about 16-20% of total glandular lipids, were shown to be composed primarily of sphingomyelin.
通过对从家鸡外耳道底部皮肤的分泌物以及分离出的整个腺体中分别提取的脂质材料进行薄层色谱分析，鉴定出了六类中性脂质，即三酰甘油（TG）、游离脂肪酸（FFA）、单酯蜡（MW）、游离和酯化固醇（FST和SE）以及角鲨烯（SQ）。分泌脂质中MW组分（17.03%）、TG（22.23%）和SQ（14.66%）占相当比例，而TG是分离腺体脂质中的主要成分（41.10%）。极性脂质约占腺体总脂质的16 - 20%，主要由鞘磷脂组成。
