Objective: To study chemical constituents of Gnaphalium affine. Method: The ethyl acetate extract part was separated and purified by silica gel column chromatography and Sephadex LH-20.The compounds isolated chemical structures were identified by their spectral data (1H-NMR
13C-NMR). Result: Nine compounds were isolated from the ethyl acetate extract portion. They were identified as n-tetratriacontanol (1)
paoriscabratine (2)
glyceryl monopalmitate (3)
9
16-dioxo-10
12
14-octadeca-trienoic acid(4)
tithoniamide B(5)
corchoionol C (6)
daucosterol (7)

4'-tetrahydtoxysilbene-2-O-β-D-glucopyranoside (8). Conclusion: Compound 3 was isolated from the genus Gnaphalium for the first time and compounds 1
2
4-6
8 were isolated from the family Compositae for the first time.
