基于化学成分稳定性的钩藤药学研究进展

钩藤为临床常用中药,也是天麻钩藤饮、羚角钩藤汤等一些著名中药复方的主药。历代本草文献有钩藤入煎剂需"后下"的记载,现代药学研究表明钩藤的生物碱类成分具有不稳定性。钩藤生物碱的不稳定,为钩藤的研究与应用带来诸多问题,如历版《中国药典》均未收载钩藤含量测定的标准,严重影响了钩藤药材的质量控制及其应用。作者围绕钩藤化学成分的稳定性,系统整理了历代本草文献及《中国药典》关于钩藤"后下"的记载,并通过查阅、分析近几十年国内外关于钩藤的化学成分及其稳定性、药理作用、提取工艺、质量分析等研究概况,为钩藤的进一步研究、开发提供参考依据。

Pharmaceutical research progress of rhynchophylla based on chemical stability

Rhynchophylla is a Chinese herb commonly used in clinical practice. It's also the primary herb of some famous Chinese herbal compound such as Tianma Gouteng decoction, and Lingyang Gouteng decoction. According the record from many previous materia medica literatures, rhynchophylla should be added later during decoction. Pharmaceutical research showed that rhynchophylla alkaloids were not stable. Which has resulted in many problems in the research and its application. For example, there was not a quantitative determination method in "Chinese Pharmacopoeia" of past and present versions, which seriously impacted its quality control and product application. Firstly, records from previous materia medica literatures and "Chinese Pharmacopoeia" were systematically sorted based on the chemical stability of rhynchophylla. Secondly, pharmaceutical research including chemical compositions and their stability, pharmacological effects, extraction process and quality analysis, was reviewed after reference of literatures published at home and abroad in recent decades. Positive reference and evidence for further research and development of rhynchophylla will be provided in the article.
