title: Structural analogues of cumambrin B from the flower of Chrysanthemum boreale.
abstract: The structural analogues of cumambrin B (1, 2, 3, 4) were isolated from the flower of Chrysanthemum boreale Makino. The structures of compounds were determined by two-dimensional 1H-1H COSY and 13C-1H COSY spectra with the aid of homonuclear and heteronuclear double resonance experiment. The stereochemistry of compounds has been verified from single crystal X-ray diffraction of cumambrin A (2). The antimicrobial activities of these guaianolides have been studied.
