Determination of Crystal Structure of Schisandrone

Abstract

Abstract: The needle crystal of Schisandrone, C₂₁H₂₄O₅, which is colorless and transparent, belongs to triclinic system. The unit cell parameters are a=9. 109(3), 6 = 9. 749(2), c= 11. 663(1) Å; α = 65.21(1), β=89. 82(1), γ=89. 96(2)(°); Z=2.In all the calculations of structure analysis, Direct Method programme of MULT AN 82 was used. All of the atomic coordinates and thermal parameters have been refined to R=0. 060 for 3521 reflections having I>3. Oσ(I). The diffractometry result shows that Schisandrone is a 4-aryltetralone lig-nan, which is the same as the result of spectroscopic determination.

Key words: Schisandrone, Triclinic system, Crystal structure, Schisandra sphenonthera Rehd. et Wils
