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.
