Abstract

Abstract The purpose of our study was to compare the chemical compositions and antimicrobial and antioxidant activities of Pycnocycla spinosa and Pycnocycla flabellifolia essential oils. cis-Asarone (62.5%) and widdra-2,4(14)-diene (9%) were the main components of P. spinosa aerial part essential oil, while elemicin (60.1%) and caryophyllene oxide (9.8%) were the main components of P. spinosa seed essential oil. α-Phellandrene (25.5%), p-cymene (15.3%), and limonene (13.3%) were found in P. flabellifolia essential oil. The inhibition zone diameters for P. flabellifolia essential oil were significantly higher than for the two other essential oils from P. spinosa (p<0.05). In broth dilution assay (µL/mL), the sensitive microorganism to Pycnocycla sp. (P. spinosa, P. flabellifolia) was Aspergillus niger, followed by Candida albicans. In 2,2-diphenyl-1-picrylhydrazyl (DPPH) system, P. spinosa aerial parts essential oil (IC50=548 µg/mL) had higher antioxidant activity than that of two other essential oils.
