CONSTITUTION OF VOLATILE OILS FROM THREE KINDS OF PTERIDOPHYTE PLANTS

Volatile oils from pteridophyte plants, namely Selaginella moellendorfii Hieron, Lygodium japonicum (Thunb.)Sw. and Pterismultifida Poir., were obtained by hydrodistillation. The oils obtained were analyzed by GC-MS. More than 90,38 and 57 peaks were separated respectively,and 86,36 and 55 compounds representing 95.56%,94.74% and 96.49% of the oils respectively were identified which indicated that there were 16 kinds of identical substances in the oils. Essential oil constituents from S. moellendorfii, L. japonicum and Pterismultifida were mainly higher alkanes, alkenes, alcohols, phenols and aldehydes.
