[Analysis of Volatile Components of Polypodium hastatum by GC-MS].

To further reveal the chemical constituents of Polypodium hastatum, volatile components from this plant were investigated.The volatile components were extracted under reflux from the whole plant of Polypodium hastatum, and then analyzed qualitatively and quantitatively by GC-MS.60 volatile components were detected and of all components detected, the structures and relative contents of 34 volatile compounds were elucidated.In the volatile components identified, most are fatty acid esters, especially methyl and ethyl esters, which compose the major volatile chemical constituents of Polypodium hastatum.
