有柄石韦和绒毛石韦叶的挥发油成分分析

Analysis on the Essential Oil of the Leaves of Pyrrosia petiolosa vs.Pyrrosia subfurfuracea

目的:分析有柄石韦和绒毛石韦叶的挥发油成分。方法:采用顶空固相微萃取和气-质联用技术(HS-SPME-GC-MS法)进行分析。色谱柱为HP-5MS石英弹性毛细管(30.0m×250μm×0.25μm),载气为高纯氦气(99.999%),流速为1.0mL.min-1,电离方式为EI源,电离能量为70eV。结果:首次从有柄石韦叶中鉴定出39种化合物,从绒毛石韦叶中鉴定出29种化合物,其中有12种二者是相同的。结论:2种石韦属植物叶的挥发油成分有明显的相同点,但是二者的主要成分有着根本的区别。有柄石韦叶中的2,6-二叔丁基对甲苯酚和绒毛石韦叶中的石竹烯具有药用价值。

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/μm × 0.25/μm） . 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, hut 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.
