Determination of Volatile Organic Compounds in Some <i>Epipactis</i>, <i>Neottia</i>, and <i>Limodorum</i> Orchids Growing in Basilicata (Southern Italy)

Abstract

SPME analysis of the scent of Epipactis microphylla showed the presence of limonene as the main component of the scent. Other components were 2,4,4,6,6,8,8-heptamethyl-1-nonene, pentadecane, and heptadecane. The scent of Epipactis palustris was characterized by pentadecane, 2,4,4,6,6,8,8-heptamethyl-1-nonene, and heptadecane. The scent of Neottia nidus avis showed the presence of kaur-16-ene as the main component of the scent. Other components were heinecosane, tetradecane, pentadecane, hexadecane, heptadecane, and 5,9,13-trimethyl-4,8,12-tetradecanal. The scent of Neottia ovata is due to pentadecane, hexadecane, and heptadecane. The scent of Limodorum abortivum showed the presence of 2,4,4,6,6,8,8-heptamethyl-1-nonene, pentadecane, hexadecane, heptadecane, and 2-(dodecyloxy)-ethanol.
