Abstract

A new norditerpenoid and six new triterpenoids were isolated from the roots of Salvia kronenburgii The new diterpenoid was kronenquinone (1). The new triterpenoids were 1 beta,2 alpha,3 beta,11 alpha-tetrahydroxy-olean-12-ene (2), 1 beta,2 alpha,3 beta,11 alpha-tetrahydroxy-urs-12-ene (3), 2 alpha-acetoxy-urs-5,12-diene-3 beta,11 alpha-diol (4), 3 alpha-acetoxy-urs-12-ene-1 beta,11 alpha-diol (5), 1 beta,3 alpha,11 alpha-trihydroxy-urs-12-ene (6), 2 alpha,3 beta,11 alpha-trihydroxy-urs-12-ene (7), and the known triterpenes 3 beta-acetoxy-urs-12-ene-1 beta,2 alpha,11 alpha-triol (8) and 3 beta-acetoxyolean-12-ene-1 beta,2 alpha,11 alpha-triol (9). Structures were determined by NMR and MS techniques.
