Structure of a New Alkaloid from the Roots of Glycyrrhiza Yunnanensis

Abstract

Abstract: Anew 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,M_w=246.31,Z=4,D=1.253g/cm³,μ(Mo-Ka)=6. 458 cm^-1,F(000)=528.Atotal of 1168 independent reflections were observed.The final R=0.058 and R_w=0.066.

Key words: Glycyrrhiza yunnanensis, Alkaloid, Glyyunnanenine, Crystal structure
