White-birdlime prepared from Ilex integra THUNBERG in remarkably viscid. In order to examine the reasons of viscosity, its components and physical properties were examined. The birdlime mainly consisted of lipids (as 'crude lipids', 91%) which contained 68% of triterpene alcohols, α-amyrin, β-amyrin, lupeol, bauerenol, betulin and erythrodiol, and 26% of fatty acids, which were palmitic, linoleic and linolenic acids, as major components. And they existed as ester forms of triterpene alcohols and fatty acids. The lipids also contained a samll amount of free acids, triterpene alcohols, and phospholipid, and the de-generated compounds of triterpenes and unsaturated fatty acids as minor components.
