Abstract

Velasco-Negueruela, A.; Sanz, J.; Pérez-Alonso, M. J. & Palá-Paúl, J. 2004. The volatile components of the aerial parts of Melittis melissophyllum L. subsp. melissophyllum gathered in Spain. Bot. Complut. 28: 133-137. The volatiles obtained by hydrodistillation and thermal desorption (TD) from the aerial parts of Melittis melissophylum subsp. melissophyllum were studied by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS). The oil from the fresh plant was shown to contain 8,11,14-eicosatrienoic acid (31.4%), hexadecanoic acid (10.9%), bicyclogermacrene (8.1%), germacrene D (7.1%) and b-caryophyllene (7.0%) as main constituents and minor amounts of 1-octen-3-ol (3.9%) and phytol (2.8%), whereas the oil from the air dried plant had 8,11,14-eicosatrienoic acid (29.1%), hexadecanoic acid (21.4%), phytol (16.0%) and spathulenol (5.2%) as major components In the volatiles obtained by direct thermal desorption of both fresh and dried plant, coumarin (2H-1-benzopyran-2-one) (82.6 y 81.1%) was shown to be the most important constituent together with phytol (1.5 y 6.3%) and hexacosane (6.4 y 4.3%).
