Abstract:
Three new monoterpenoid compounds have been isolated from extracts of the stem barks of Winchia calophylla A. DC. The new compounds include two cyclo-diglycosides, wincaloside A (2) and wincaloside B (3), and a derivative of tetrahydroxycyclohexane-carboxylic acid, winchiepoxide (1). Their structures have been elucidated by spectroscopic and chemical methods.
