Triterpenoids and other compounds from Salvia roborowskii Maxim.

ABSTRACT

Two new triterpenoids, 2 alpha-hydroxy-3 beta-methoxyurs-12-en-28-oic acid and 3 alpha-hydroxy-2 alpha-methoxyurs-12-en-28-oic acid as well as 25 known compounds were isolated from the whole plant of Salvia roborowskii Maxim. Their structures were elucidated by means of spectral data and chemical transformation. This is the first report on the chemical constituents of this plant. The presence of eugenyl beta-D-glucopyranoside 22 in a plant of the genus Salvia is also reported for the first time.
