木槿皮、土荆皮、水翁皮的本草考证及现代研究

Textual research on Hibisci Cortex,Pseudolaricis Cortex and Cleistocalycis Cortex

目的考证分析木槿皮、土荆皮、水翁皮三者的用药历史,为正确使用和进一步开发利用这三种药材提供依据。方法查阅历代本草文献,结合现代研究,进行综合比较。结果历代本草文献所记载的木槿皮与目前一致,为锦葵科植物木槿的干燥茎皮或根皮;土荆皮为松科植物金钱松的干燥根皮或近根树皮;水翁皮为桃金娘科植物水翁的干燥树皮。结论三者来源于不同科属的植物,用法、用途不同,临床应用时应根据临床症状,对三者加以鉴别后使用,且三者的主要化学成分相差甚远,不可互相代用。

Objective To investigate the history of medication of Hibisci Cortex, Pseudolaricis Cortex, Cleistocalycis Cortex and provide the basis for the rational use of these herbals. Methods Herbal literatures in all ages were reviewed and compared with modern research in order to distinguish the three crude drugs. Results Hibisci Cortex is obtained form Hibiscus syriacua L. , the records of which in the past times comply well with the present literatures. Pseudolaricis Cortex and Cleistocalycis Cortex are derived from Pseudolarix kaempferi Gord. and Cleistocalyx operculatus （ Roxb. ） Merr. et Perry respectively. Conclusion The three crude drugs are derived from different species. Their usages and ingredients differ dramatically. Therefore their clinical applications should not be confused but vary with clinical symptoms.
