The Dufour's gland of Anthophora abrupta, a solitary bee, secretes a complex mixture of liquid triglycerides containing one long-chain and two shortchain fatty acids. This is applied inside the earthen brood cells and added to the provision, where it is converted, perhaps by enzymes from the bee's saliva or gut, to solid diglycerides that are later eaten by the bee larvae. This use of Dufour's gland secretion as food and its nutritive function are reminiscent of the royal jelly secreted by honey bees.
独居蜜蜂Anthophora abrupta 的杜佛氏腺分泌出一种复杂的液体三酸甘油脂混合物，含有一长链和两短链脂肪酸。这种物质会被涂抹在土制的育卵室里，也会添加到给幼虫的食物中。在那里，它可能会被蜜蜂唾液或肠道中的酶转化为固体的二酸甘油脂，之后被幼虫吃掉。杜佛氏腺分泌物的这种作为食物的用途和其营养功能，让人联想到由蜜蜂分泌的蜂王浆。
