摘　　要：目的:探讨不同商品规格地黄与化学成分之间的关系,从化学成分角度为制定地黄药材商品规格标准和等级划分提供实验依据。方法:按地黄的等级、表面颜色、断面颜色和断面质地对地黄药材进行分类,以环烯醚萜苷类、糖类、水分、总灰分、酸不溶性灰分及水溶性浸出物为指标,探讨不同商品规格地黄中化学成分的变化规律。结果:地黄等级、表面颜色和断面质地对化学成分的影响较小,断面颜色对化学成分的影响较大;随着地黄断面颜色的逐渐加深,环烯醚萜类、寡糖类成分含量逐渐降低,而单糖、多糖类含量逐渐升高。结论:地黄的商品规格与化学成分之间具有一定的相关性。This paper was aimed to explore the relationship between different commercial specification and chemical constituents on Radix Rehmanni, which provided experimental evidences for drawing up the commodity commercial specification and grading criteria of Radix Rehmanni. Several classified indexes, including grade, surface color, section color, section texture were carried to explore the change rules of chemical constituents by setting the contents of iridoid glycoside, sugars, water content, total ashes, acid-insoluble ashes and water extract as the markers. The results showed that the grade, surface color and section texture had less impact on chemical constituents. However, the section color had more influence. Along with the section color gradually being deepened, the contents of iridoid glycoside and oligosaccharides of Radix Rehmanni were lower, and the contents of monosaccharide and polysaccharide were higher. It was concluded that there was correlation between commercial specification and chemical constituents of Radix Rehmanni.
