Monoterpenoids and their glycosides from Winchia calophylla.
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.
