Chemical composition of the essential oils from the roots, fruits, leaves and stems of Pimpinella cumbrae Link growing in the Canary Islands (Spain) uri icon

abstract

  • The oil constituents from the roots, fruits, leaves and stems of Pimpinella cumbrae Link gathered in the Canary Islands, Spain, have been studied by GC and GC-MS in combination with retention indices. The major constituents in the root oil were found to be isokessane (17%), beta-dihydroagarofuran (15%), 2-methylbutyric acid (10%), geijerene (10%) and pregeijerene (7%). In the fruit oil the main components found were alpha-bisabolol (39%), delta-3-carene (16%) and limonene (8%). In the leaf oil, a-bisabolol (53%) and delta-3-carene (11%) were the predominant constituents. The most important compounds from the stem oil were alpha-bisabolol (39%), isokessane (10%) and beta-dihydroagarofuran (9%). Pseudoisoeugenol esters were also detected in the oils from the roots, fruits and stems. These components were partially hydrolysed in the course of prolonged hydrodistillation to 2-methyl-5-methoxybenzofuran. Copyright (C) 2002 John Wiley Sons, Ltd.
