Volatile Constituents of Floral Scents from Encyclia cordigera (Kunth) Dressler and E. randii (Barb. Rodr.) Porto & Brade (Orchidaceae)

Encyclia cordigera is native from Central America tropical region, and Encyclia randii occurs at Brazilian Amazon environment domains. Floral concentrates from both Encyclia species were extracted, analyzed by gas chromatography-mass spectrometry, and identified compounds belong to terpenoids, phenylpropanoids, and fatty acid derivatives classes. Primary constituents of the E. cordigera floral scent were β-ionol (45.4%), terpinen-4-ol (12.4%), benzyl benzoate (5.6%), and indole (5.0%). (2E,6Z)-Farnesol (24.9%), heptanal (11.8%), (E)-nerolidol (9.4%), nonanal (6.4%), p-vinyl-guaiacol (6.0%), a...
