The oily droplets on the pupal integumental hairs of the squash beetle Epilachna borealis contain a mixture of alpha-, beta-, gamma-, and delta-tocopheryl acetates as major constituents. In addition, the secretion contains a number of minor components that appear to be dehydrocongeners of the major components. This is the first report of the occurrence of acetate esters of any tocopherol in nature.
北美的南瓜瓢虫（Epilachna borealis）蛹体体表毛发上的油滴含有α-、β-、γ-和δ-生育酚乙酸酯的混合物作为主要成分。此外，该分泌物还含有一些次要成分，这些成分似乎是主要成分的脱氢类似物。这是自然界中首次出现任何生育酚乙酸酯的报道。
