A method for the synthesis of lappaconitine hydrobromide by the reaction of dibromoalkyl with lappaconitine is presented. Lappaconitine hydrobromide was determined by IR, 13C NMR, HRMS spectra, elemental analysis and X-ray diffraction analysis. Through intermolecular hydrogen bonding, the similar super molecule netlike structure is formed. Crystal data: monoclinic, P21, a＝1.0619(2) nm, b＝1.2196(3) nm, c＝1.2282(2) nm, β＝90.87(1)°, V＝1.59037(54) nm3, Z＝2, Dm＝1.428 g/cm－3, F(000)＝720.0, μ＝1.349 mm－1. Rings A, B, C, D, E and F present boat, chair, envelope, boat, boat and envelope forms, respectively. The stereo absolute configuration of lappaconitine hydrobromide was determined as 1S,4S,5S,7S,8S, 9S,10S,11S,13R,14S,16S,17R.
