摘要: 本文建立了用紫外分光光度法测定丹皮酚-β-环糊精包合物含量的方法,用石油醚(90~120℃)作溶剂,检验波长为316nm,测定溶液的线性范围为4~20μ/g/ml,r=0.9999,吸收系数(E1cm1%)为396.本法操作简便,重现性好,结果准确。Abstract: A ultraviolet spectrophotometric rnethod for quantitative determination of paeonol-β-cyclodextrin encapsuled was established in the paper. Petroleum benzine was used as the solvent. The detective wavelength was 316nm. The method was linear within the concentration range of 4~20μg/ml,r=0.9999. Absorbtivity (E1cm1%) was 396.
