Volatile Constituents of the Seeds and Fruit of Pycnocycla nodiflora

Abstract

The essential oil contents of the fruit and seeds of Pycnocycla nodiflora Decne. ex Boiss. growing wild in southern Iran were found to be 0.05% and 0.1% (v/w), respectively based on the fresh weight. The oils were analyzed by GC and GC–MS. Twenty-eight and twenty-seven constituents, representing 94.7% and 89.6% of the oils were identified, respectively. The major components of the P. nodiflora fruit oil were identified as E-sesquilavandulol (18.6%), spathulenol (11.9%), δ-cadinol (9.0%), t-cadinol (8.9%) and β-caryophyllene (7.9%), while the main components of that of the seeds were characterized as E-sesquilavandulol (17.2%), lavandulyl acetate (13.5%), β-caryophyllene (11.1%), bicyclogermacrene (10.5%), δ-cadinol (9.0%) and t-cadinol (6.8%).
