Essential oils composition of Polystichum montevidense (Spreng.) Rosenst (Dryopteridaceae) and Podocarpus parlatorei Pilg. (Podocarpaceae)

Abstract

The essential oils of Polystichum montevidense (Spreng.) Rosenst. (Dryopteridaceae) and Podocarpus parlatorei Pilg. (Podocarpaceae) were analyzed for the first time by means of GC and GC-MS. From Polystichum montevidense sixteen compounds were identified, representing 98.0% of the oil, whereas Podocarpus parlatorei seventeen compounds were identified, representing 97.7% of the oil. Polystichum montevidense contained higher amounts of α-pinene (21.3%), α-terpineol (14.8%), pulegone (14.7%), and α-muurolene (10.2%), whereas the major oil constituents of Podocarpus parlatorei were found to be terpinen-4-ol (29.0%), germacrene D (17.7%) and α-eudesmol (16.5%).
