Abstract

CICCIO, José F.  and  GOMEZ-LAURITO, Jorge. Volatile constituents of the leaves of Siparuna thecaphora (Siparunaceae) from Turrialba, Costa Rica. Rev. biol. trop [online]. 2002, vol.50, n.3-4, pp.963-967. ISSN 0034-7744.

The composition of the essential oil from leaves of Siparuna thecaphora (Poepp. et Endl.) A. DC. collected in Turrialba, Costa Rica, was determined by capillary GC/MS. Seventy-six compounds were identified corresponding to ca. 95% of the oil. The major components were germacrene D (32.7%),  α-pinene (16.3%), β - pinene (13.8%) and β -caryophyllene (4.1%). Thirty-one minor compounds were identified for the first time in this genus of plants.

Keywords : Siparuna thecaphora; Siparunaceae; essential oil composition; germacrene D; α -pinene; β -pinene; β -caryophyllene.
