Abstract

The new labdane diterpenes otostegin A (2), otostegin B (6) and 15-epi-otostegin B (7) were isolated from the aerial parts of Otostegia. fruticosa, besides the previously known labdanes preleoheterin (1), leoheterin (3), leopersin C and 15-epi-leopersin C (4, 5), ballonigrin (9) and vulgarol (11), along with the iridoid glucoside 8-O-acetylharpagide (10). The structure elucidation of all the isolated compounds was based on their spectral data and chemical derivatization.
