Prangos, essential oil, hs-spme/gc-ms.
The essential oil of the dried flowering aerial parts of Prangos pabularia Lindl. and Prangos peucedanifolia Fenzl. were analyzed by means of HS-SPME/GC-MS. As a result thirty four and thirty seven components were identified representing 91.3% and 89.5% of the oil of P. pabularia and P. peucedanifolia, respectively. The main constituents of P. pabularia were α-pinene (32.4%), δ-3-carene (12.4%), germacrene D (8.1%), limonene (6.4%) and bicyclogermacrene (6.2%); whereas α-pinene (38.1%), bicyclogermacrene (11.3%) and δ-3-carene (9.2%) were the major constituents of P. peucedanifolia. With this study, chemotypes of P. pabularia and P. peucedanifolia were detected α-pinene and δ-3-carene. Studied plant samples were found to be rich in respect to essential oils. The results were discussed in consideration of natural products, renewable resources, chemotaxonomy and potential medical uses of these plants.
