Diterpenoids from Salvia ceratophylla

Abstract

Salvia ceratophylla L. has yielded four known and two now diterpenoids together with two triterpenic acids, a steroid and a flavone. The structures of the compounds were established by spectroscopic analyses. One of the known compounds candidissiol exhibited a high antibacterial activity against Staphylococcus epidermidis and Proteus mirabilis.
