Objective: To study the chemical constituents of the ethyl acetate extract of Liparis nervosa. Method: Chemical constituents were isolated by Column chromatography on Silica gel and Sephadex LH-20

their structures were identified by physicochemical characters and spectroscopic analysis or comparison with standard compounds. Result: Seven compounds were isolated and identified as 2

2-dimethyl-8- (3-hydroxyisoamyl)chroman-6-carboxylic acid (1)

linoleic acid (2)

α-spinasterol glucoside (3)

glycerol monopalmitate (4)

genkwanin(5)

apigenin(6)

butane diacid(7). Conclusion: Compounds 1 was a new natural product

2-7 were isolated from L. nervosa for the first time.
