Eupatorium salvia

The structure of the epoxy-dialdehyde (15), from Afromomum daniellii (Zingiberaceae), was established by correlation with c -12-norambreinolide. The hydroxy-acid (16), salvic acid from Eupatorium salvia,and the ring B seco-labdane jhanic acid (17) from Eupatorium jhanii are two further diterpenoids from these species of the Compositae. The structure of the latter rests on interpretation of the H and C n.m.r. data. Gutierrezia lucida (Compositae) contains the 13-epimeric acids (18) related to agathic acid together with the butenolide (19). Some esters of 6-hydroxylabdane-17-carboxylic acids were detected in G. mandonii. The investigation of Cistus species has continued. The ent-labdane acetyl-laurifolic acid (20) is a component of Cistus laurifolius ... 

The antimicrobial properties of the resinous exudates from twigs and leaves of Eupatorium salvia Colla were tested against 5 Gram (-) and 5 Gram (+) bacteria [200]. Comparison of the antimicrobial activities of 7-hydroxy-8(17)-labden-15 oic acid (salvic acid) and its acetate, both compounds isolated from the plant, with that of the crude extract suggested that the latter ester derivative was the major active component in the exudates. These results validate the vernacular medicinal use of Eupatorium salvia as an antiseptic agent.
