Resumo
Multivariate analysis of essential oil compositions of thirteen Hypenia species revealed
the presence of two taxonomic clusters. Cluster I included three species belonging to section
Densiflorae in addition to H. subrosea and H. aristulata, and showed the highest percentages
of a-muurolol (5.85 ± 3.08%). In Cluster II, which contained eight species belonging to
section Laxiflorae, the major discriminant constituents were (E)-caryophyllene (7.09 ± 4.88%),
germacrene D (18.1 ± 11.4%), and bicyclogermacrene (6.65 ± 1.19%). All essential oils showed a
predominance of sesquiterpenes, such as spathulenol (4.5-31.6%), caryophyllene oxide (2.2-14.4%)
and selin‑11‑en-4a-ol (0-34.8%). Furthermore, identical clusters were revealed by multivariate
analysis of chemical constituents based on carbon skeletons, as well as on 18 morphological leaf
characters of the species studied.
