Acylated farnesyl diglycosides from Guioa crenulata

Chemical investigation of the methanolic extract of the leaves of Guioa crenulata led to the isolation and characterisation of four farnesyl diglycosides, crenulatosides A, B, C and D, along with three known flavonol glycosides and one known trimeric proanthocyanidin possessing a doubly linked structure.
