Abstract
A novel cucurbitacin glycoside has been isolated from aerial parts of Kagen eckia oblonga R. et P. and shown to be 3 beta-(beta-D-glucosyloxy)-16 alpha ,23 alpha-epoxycucurbita-5,24-dien-11-one. The structure was established by usual spectroscopic and two-dimensional (2D) NMR techniques. This compound has found to be nontoxic when tested in-vivo cell culture assays. In previ ous investigations we reported 23,24-dihydrocucurbitacin F and prunasine. T his was the first report on cucurbitacins from the genus Kageneckia (Rosace ae).
