ABSTRACT
Objective:
To study the chemical constituents from Gnaphalium affine and their anti-oxidative activities.Methods:
Chemical constituents were isolated by column chromatography and semi-prepared HPLC, the structures were elucidated by spectral data and physicochemical properties. DPPH free radical scavenging activities of compounds 1,3-11, and 16 were determined.Results:
Seventeen compounds were isolated and respectively identified as apigenin (1), dihydroapigenin (2), luteolin (3), chrysin (4), wogonin (5), stimasterol (6), β-sitosterol (7), ursolic acid (8), oleanolic acid (9), 19α-hydroxyl-oleanolic acid (10), 2α, 3α, 19α-trihydroxy-28-norurs-12ene (11), α-amyrin acetate (12), β-amyrin acetate (13), patriscabratine (14), aurantiamide acetate (15), 4'-hydroxydehydrokawain (16), and isovanillin (17). Compounds 1 and 3-5 had significant anti-oxidative activities.Conclusion:
Compounds 2,4,5,11-15, and 17 are isolated from G. affine for the frist time.
