A new alkaloid isolated from the roots of Glycyrrhiza Yunnanensis Chang f.et.L.K.Tai with the formula C14H18O2N2,named as glyyunnanenine.The crystal structure has been determined by elemental analysis,UV,IR,FAB-MS,EI-MS,1HNMR,13CNMR,DEPT(90°,135°) and X-ray diffraction analysis.The crystal is orthorhombic with space group P212121,a=0.9629(1) nm,b=1.0848(1) nm,c=1.250(2) nm,V=1.3508(2) nm3,Mw=246.31,Z=4,D=1.253g/cm3,μ(Mo-Ka)=6. 458 cm(-1),F(000)=528.A total of 1168 independent reflections were observed.The final R=0.058 and Rw=0.066.
