Hydrodistilled essential oil of Peperomia pellucida (L.) Kunth, collected from the foothills of Uttarakhand was analyzed using gas chromatographyâflame ionization detection (GCâFID) and GCâmass spectrometry (GCâMS). A total of fifty constituents, representing 94.3â97.9% of the total oil composition, were identified. Major constituents of the oil of whole herb were carotol (26.6â32.0%), dill apiole (25.1â30.2%), pygmaein (5.5â10.5%), (E)-caryophyllene (5.6â8.3%), germacrene D (3.1â4.7%), Î²-elemene (3.0â4.2%), camphor (< 0.05â2.8%), daucene (0.8â2.7%), apiole (1.5â2.5%), Î²-bisabolene (0.2â2.2%) and bicyclogermacrene (1.6â2.1%). However, the root oil contained higher amount of apioles (dill apiole 63.9% and apiole 9.2%) compared with the aerial parts (dill apiole 20.7% and apiole 1.1%) of P. pellucida.
