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

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%),ˇ-dihydroagarofuran (15%), 2-methylbutyric acid (10%), geijerene (10%) and pregeijerene (7%). In the fruit oil the main components found werę -bisabolol (39%), υ-3-carene (16%) and limonene (8%). In the leaf oil,˛-bisabolol (53%) and υ-3-carene (11%) were the predominant constituents. The most important compounds from the stem oil were˛-bisabolol (39%), isokessane (10%) andˇ-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.

Essential oil composition ofPimpinella aurea D.C. from Iran

“…The yield of arial part of P. aromatica was 6.1%. [2][3][4][5] Thirty-two constituents were identified in the stem + leaf oil, 18 in the flower oil and eight in the seed oil.…”

“…Pseudoisoeugenol esters were also detected in the oils from the roots, fruits and stems. 5 The aim of this study was to determine of the quantity and quality of oils from different plant parts of P. aurea. For this purpose, the oil compositions of three parts of P. aurea were characterized.…”

Study of the Oil Constituents Extracted From Aerial Parts ofPimpinella aureaDC. From Central Iran

“…The main components comprising 46.4% of the oil were b-caryophyllene (13.6%), b-bisabolene (12.2%), (E)-b-farnesene (10.4%) and b-sesquiphellandrene (10.2%). Although limonene (3,16,17) and (E)-anethole (3) have been reported in other Pimpinella species as the major compounds, neither of them was found in this oil. b-Caryophyllene, which was the first major component of this oil, has been reported in the oil of some Pimpinella species such as P. acuminata (18) and P. aurea from Northern Iran (19) and in four Pimpinella species growing in Turkey (7).…”
