In order to improve the processing technology of “Huangjing” by using modern technology，the processing method were studied in this paper.According to textual research，Huangjing was first recorded in the “Ming Yi Bie Lu”，and its processing method was first recorded in the “Internal Chapter of Baopuzi”.In ancient times，the original medicinal plants of “Huangjing” were mainly “Dianhuangjing”，“Huangjing”，“chumaohuangjing”,”Lunye Huangjing”，which were used as medicinal in the Song Dynasty，and began to be used as medicinal in the Republic of China.The mainstream primordial species of Polygonatum cyrtonema.Ancient processing methods of “Huangjing” included “nine steaming and nine aeration”，“black bean processing” and “vine processing”，the first one was the main processing methods.Modern processing methods of “Huangjing” include drying，honey steaming，wine steaming，etc.In modern scientific research，the uncertainty of the original habitat，the age of rhizome and the proportion of the quality of rhizome for processing test may lead to the conclusion that the variation of polysaccharide content in rhizome of “Huangjing” is quite different.On the basis of ensuring the consistency of rhizome materials，the correlation between different processing methods and steaming times，polysaccharide content in rhizome of “Huangjing” was studied，and the optimum processing method of “Huangjing” was evaluated from the screening of effective components after processing，which has more guiding significance for production.
