摘　　要：研究了紫外光谱分析歧化松香中脱氢枞酸含量的三种方法,结果表明紫外光谱方法适宜分析脱氢枞酸含量高、背景干扰少的歧化松香产品,紫外分光光度法、紫外吸收光谱一元线性回归法、紫外吸收光谱导数法的加标回收率分别在81%～101%,97%～109%,98%～103%之间.Three methods of Ultraviolet Spectrophotometry (UV) have been employed to measure the dehydroabietic acid in disproportionated rosin. The results show that various analytical methods of UV are suitable for analysing the disproportionated rosin compositions with high content of dehydroabietic acid and low interference of background caused by the samples. The recovery of these methods, UV, UV linear regression equation and derivative by UV linear regression equation are 81%～101%,97%～109%and 98%～103%,respectively.
