Abstract

Two beta-orcinol depsidone lactones, the methyl ethers of menegazziaic acid and stictic acid were isolated along with glyceryl trilinolate and usnic acid from an Usnea sp. new to Sri Lanka growing on rotting trees of Acacia decurrans. Usnic acid exhibited potent antitermite activity against a common pest of tea, Glyptotermes dilatatus, at low elevations.

摘要

从生长在金合欢腐烂树上的一种对斯里兰卡来说是新物种的地衣中，分离出了两种β - 苔黑酚缩酚酸内酯，即扁枝衣酸和石耳酸的甲醚，同时还分离出了甘油三亚油酸酯和松萝酸。松萝酸在低海拔地区对一种常见的茶树害虫——宽头散白蚁表现出了很强的抗白蚁活性。
