[Studies on antibacterial constituents from Gerbera anandria (L.) Sch Bip. IV].
Thirteen compounds have been isolated from Gerbera anandria (L.) Sch Bip. Among them, three new compounds were elucidated by chemical correlations and spectral analyses. They are 3.8-dihydroxy-4-methoxy-coumarin (XIX), 3,8-dihydroxy-4-methoxy-2-oxo-2H-1-benzopyran-5-carboxylic acid (XVII), and 5,8-dihydroxy-7-(4-hydroxy-5-methyl-coumarin-3-)coumarin (XXI).
