ABSTRACT
OBJECTIVE:
To analyze the essential oils from the leaves of Pyrrosia petiolosa or Pyrrosia subfurfuracea.METHODS:
The essential oils from the leaves of P.petiolosa or P.subfurfuracea were analyzed by head-space solid microextraction coupled with GC-MS(HS-SPME-GC-MS) on capillary column HP-5 MS (30.0 m?250 ?m?0.25 ?m).The carrier gas was helium(with a high purity of 99.999%) at a flow rate of 1.0 mL?min-1.The ionization mode EI ionization source with electron energy of 70 eV.RESULTS:
For the first time,39 constituents were identified from the leaves of P.petiolosa and 29 constituents were identified from the leaves of P.subfurfuracea.Of which,12 constituents were mutual in both samples.CONCLUSION:
The components of the essential oil in leaves of the two Pyrrosia species bear some similarities,but the essential components of the two Pyrrosia species are different from each other fundamentally.Butylated hydroxytoluene in the leaves of P.petiolosa and caryophyllene in the leaves of P.subfurfuracea have medicinal value.
