摘要: 采用萃取法、柱层析法和重结晶法对产自四川省双流县的姜黄中的姜黄素进行了分离和纯化,利用IR,UV,MS,1HNMR,13CNMR和X-ray单晶衍射等测试手段对姜黄素的分子与晶体结构进行了表征,证实了姜黄素的晶体结构属于单斜晶系,P2/n空间群。晶胞参数为:a=1.2695(3)nm,b=0.72075(16)nm,c=1.9960(4)nm,α=90°,β=95.098°,γ=90°,每个晶胞中含有四个姜黄素的分子。姜黄素的分子为非线型结构,呈现出酮式-烯醇式互变异构现象。

Abstract: A single crystal of curcumin was obtained from the turmeric of Shuangliu County of Sichuan Province, China by usingseparation and purification technique of solvent extraction, column chromatography and recrystallization etc. The molecular andcrystal structure of curcumin were identified by IR, UV, MS, 1HNMR, 13CNMR and X-ray single crystal diffraction. Curcumincrystal belongs to monoclinic with P2/n space group. The unit cell data are: a = 1.2695(3)nm, b = 0.72075(16) nm, c=1.9960(4) nm,α=90°β=95.098°γ=90°. The molecule of curcumin damonstrates a nonlinear keto-enol tautomerism structure andthere are four curcumin molecules in each cell.

Key words: curcumin, turmeric, separation and purification, characterization, molecular structure
