摘　　要：目的：建立红花龙胆的质量标准。方法：采用薄层色谱鉴别及高效液相色谱法测定红花龙胆中芒果苷含量,并测定水分、总灰分、酸不溶性灰分。结果：样品以对照药材和芒果苷为对照物质进行薄层色谱鉴别能很好比对和检出;红花龙胆药材含芒果苷质量分数为0.7%~4.4%（平均2.8%）,水分为6.1%~8.6%（平均7.2%）,总灰分为3.7%~10.8%（平均6.6%）,酸不溶性灰分为0.2%~2.7%（平均1.3%）。结论：所建立的方法操作简便,准确可靠,重现性好,制订的标准限度合理,可用于红花龙胆药材的质量评价。Based on the approaches of TLC identification,HPLC for assaying managiferin,and of the determination of water,total ash and acid-insoluble ash in 12 samples,collected from southwest of China,the quality standard of Gentiana rhodantha has been established.The results show the reference materia medica and mangiferin can be both well used as reference substances for TLC identification;the mass fractions of mangiferin is 0.7%-4.4%（average 2.8%）,water 6.1%-8.6%（average 7.2%）,total ash 3.7%-10.8%（average 6.6%） and acid-insoluble ash 0.2%-2.7%（average 1.3%）.The recommended standards of quantitative indexes are that the mass fractions of mangiferin is not less than 2.0%,and the water,total ash and acid-insoluble ash are not more than 9.0%,8.0% and 3.0% respectively.
