摘　　要：目的:初步制定河南产区盾叶薯蓣的质量标准。方法:在对盾叶薯蓣进行性状、显微及薄层鉴别的基础上,参照2010年版《中国药典》(一部)中方法测定水分、总灰分、酸不溶性灰分及醇浸出物含量,并利用高效液相色谱法测定薯蓣皂苷元与伪原薯蓣皂苷的含量。结果:河南产区盾叶薯蓣水分应不超过7%;总灰分不高于8%;酸不溶性灰分不得高于2%;醇溶性浸出物含量不得低于16%;盾叶薯蓣药材薯蓣皂苷元含量不得低于1%;伪原薯蓣皂苷含量不得低于0.4%。结论:方法简便、准确,建立和完善了盾叶薯蓣的质量标准。Objective： To set up the quality standards of Dioscorea zingiberensis in Henan area preliminary. Method： On the basis of discrimination in Characters, microscopic and TLC, the content of water, total ash, acid insoluble ash and alcohol soluble extractive were determined According to the method in the Chinese Pharmacopoeia （edition 2010）, and the content of diosgenin and pseudoprodioscin was determined by HPLC. Result： The moisture in Dioscorea zingiberensis should be no more than 7% ; the total ash should be within 8% ; the acid-insoluble ash should not be higher than 2% ; alcohol soluble extractive should not be lower than 16%. The content of diosgenin should not be lower than 1% , and the content of pseudoprodioscin should be higher than 0.4%. Conclusion： The study provide the reference basis for making and perfecting the quality standards system of D. zingiberensis.
