The VOs of the leaves of the 0.4-to 0.6 tall shrub Disynaphia ericoides (DC.) R.M.King & H.Rob.

(syn. Eupatorium ericoides) (King and Robinson, 1987; Matzenbacher, 1979)

were similar to those obtained from Acanthostyles buniifolius, especially due to the levels of germacrene A (5.4%) and β- elemene (9.0%). In addition to these two compounds, the VOs contained β- caryophyllene (21.3%), germacrene D (8.6%), bicyclogermacrene (15.1%), and spathulenol (8.5%).

No species from the Disynaphia genus, the type genus of this subtribe, have had its VO chemical composition previously described. The VOs obtained from D. ligulifolia, D. spathulata, and D. ericoides were similar to those in C. cruciata with a higher degree of oxidation when compared to Grazielia spp. and qualitatively different from R. tremula . The VOs from 13 species of Disynaphia remain to be described.
