By: Yang, Min Suk; Park, Ki Hun; Jang, Dae Sik; Choi, Sang Uk; Nam, Sang Hae; Shiro, Mooto Cumambrin A has been isolated from the dried flowers of Chrysanthemum boreale Makino. The complete 1H and 13C NMR assignment of cumambrin A was achieved from 2-dimensional 1H-1H COSY and 13C-1H COSY spectra with the aid of homonuclear and heteronuclear double resonance experiments The its structure has been verified by single crystal X-ray diffraction.
