黄精是一味临床应用极为广泛的补益类中药，为传统四大九蒸货之一，其炮制方法在《中国药典》2020年版中只收载了酒蒸（炖）的方式。通过从炮制工艺入手，对古代文献的分析和现行地方规范进行考察，系统梳理了黄精炮制的历史沿革、现行炮制法及其工艺要素，探讨其炮制方法背后的原理，并针对炮制终点的判定提出一致性评价策略，以期实现科学地进行炮制工艺改良，进一步为其他需九蒸九晒炮制的中药其现代原理解析及炮制工艺优化提供新思路。

Huangjing (Polygonati Rhizoma) is a widely used tonifying traditional Chinese medicine in clinical practice, and is one of the traditional four major nine steamed goods. Its processing method of wine steaming (stewing) is only included in the 2020 edition of Chinese Pharmacopoeia. This paper starts with the processing technology, analyzes ancient literature and examines current local standards, systematically reviews the historical evolution, current processing methods, and process elements of Polygonati Rhizoma processing, explores the principles behind its processing methods. A feasible consistency evaluation strategy for determining the endpoint of processing is put forward in order to improve the processing technology scientifically, further providing new ideas for the modern principle analysis and processing technology optimization of other traditional Chinese medicines that require nine steaming and nine sun drying processing.
