Paeonol was prepared by the extraction method from Moutan Cortex. Its crystal struc- ture was determined by single-crystal X-ray diffraction.The compound crystallizes in the monoclinic sys- tem, space group P21/c with a = 6.724(4), b = 8.792(6), c = 14.689(10) ?, β = 100.138(11)o, V = 854.8(10) ?3, Mr = 166.17, Z = 4, F(000) = 352, Dc = 1.291 g/cm3, μ = 0.097 mm-1, the final R = 0.0454 and wR = 0.0988 for 845 observed reflections with I > 2σ(I).
