摘要：

Two new nor-cucurbitacin glucosides were isolated from the roots of Wilbrandia sp. and their structures established as 29-nor-1,2,3,4,5,10-dehydro-25-O-acetyl-2-O-beta-D-glucopyransoyl-3,16-alpha,20(R)-trihydroxy-11,22-dioxocucurbita-6,23-diene and 29-nor-1,2,3,4,5,10-dehydro-2-O-beta-D-glucopyranosyl-3,16-alpha,20(R),25-tetrahydroxy-11,22-dioxocucurbitac-6-ene mainly by H-1 and C-13NMR of the peracetyl derivatives, including 2D experiments.
