With 95%ethanol solution as the extraction agent , eight fatty acid composition were extracted form osmunda japonica spore powder by reflux extraction method. The content of each fatty acid composition was determined by GC-MS with area normalization method. The results showed , the fatty acid contents in osmunda japonica spore powder were hexadecanoic acid 50.20%, elinoleic acid 6.96%, oleic acid 13.48%, stearic acid 7.69%, linolenic acid 5.56%, arachidic acid 3.42%, docosanoic acid 2.08%, myristic acid 0.60%.
