Two new 27-nor-triterpene glycosides, tomentosides A (1) and B (2), were isolated from Peruvian "Una de Gato" (cat's claw, plant of origin: Uncariatomentosa), a traditional herbal medicine in Peru. Their structures were determined by spectroscopic analysis and chemical interconversions. This is the first report of naturally occurring pyroquinovic acidglycosides.
从秘鲁的传统草药秘鲁“ Una de Gato”(猫爪,产地:Uncaria tomentosa)中分离出两个新的27-nor-triterpene糖苷,tomentosides A(1)和B(2)。它们的结构通过光谱分析和化学互转换来确定。这是天然存在的邻苯二酚喹诺酮酸糖苷的首次报道。
