Bacchotricuneatin

Clerodanes.—In a study of South African Macowania species, a cis-clerodane acid (28) and labdanolic acid were obtained from M. glandulosa. Deoxymarrubialac-tone (29) has been isolated from Chaiturus marrubiastrum. Linarienone (30) is another ds-fused clerodane which has been obtained from the roots of Linaria japonica (Scrophulariaceae) and correlated with linaridial. The bacchotricuneatins A (31) and B (32) are two new diterpenoid lactones which were isolated from Baccharis tricuneata (Astereae) and whose structures were determined by a combination of spectra and X-ray analysis. [Pg.127]

From another Argentinian Baccharis species, B. articulata, three diterpenes of neo-clerodane type, articulin, Fig. (3), articulin acetate and barticulidiol, Fig. (4), together with the known bacchotricuneatin A, Fig. (5), were isolated [22,23],... [Pg.708]

This diterpene lactone, bacchotricuneatin A was also isolated from B. tricuneata [24] and Baccharis cassinaefolia D. C. [25],... [Pg.708]
