Abstract: Abstract: The essential oil of the aerial parts of Verbascum undulatum Lam. was analyzed by GC and GC/MS. Thirty-six compounds were identified and the major components were 1-octen-3-ol (22.5%), α-bisabolol (10.6%) and nonanal (9.0%). Key Word Index: Verbascum undulatum, Scrophulariaceae, essential oil composition, 1-octen-3-ol, α-bisabolol.

Plant Name
Verbascum undulatum Lam., Scrophulariaceae (1).

Source
The plant material was collected in Attiki region (Greece) in May 2002, at flowering stage. A voucher specimen (PROK008b) is deposited in the Herbarium of the laboratory of Pharmacognosy, University of Athens, Greece.

Plant Part
Fresh aerial parts (inflorescences, stems and leaves) of V. undulatum were subjected to hydrodistillation for 3 h using a modified Clevenger-type apparatus to give 0.15% of essential oil. The distilled oil was collected, dried over anhydrous sodium sulfate and stored at 4°C.

Previous Works
Previous works on Verbascum undulatum concern the phytochemical analysis of the aerial parts and the roots of the plant (2–5). Concerning the essential oil of the plant, a survey of the literature reveals that the oil has not been the subject of previous study.
