山柰为姜科植物山柰KKaempferia galanga L.的根茎,苦山柰为共同属植物苦山柰K.marginata Y.H.Chen.的根茎。据文献记载苦山柰有毒,不能药用。由于二者性状极为相似,采用《中国药典》一九九○年版及文献方法鉴别较为繁琐,所以我们应用紫外光谱法进行鉴别。 1 材料及仪器 材料:来源于自贡市中药材公司、部分医疗单位以及由市场购得,经鉴定为山柰及苦山柰。 Hawthorn is the rhizome of Gingeraceae Hawthorn KKaempferia galanga L., and Hawthorn is the rhizome of Common Hawthorn K. marginata Y.H. Chen. According to literature, bitter hawthorn is poisonous and cannot be used medicinally. Because the characters of the two are very similar, it is more complicated to use the “Chinese Pharmacopoeia” 1990 edition and literature methods to identify, so we use UV spectroscopy to identify. 1 Materials and instruments Materials: Sourced from Zigong City’s Chinese herbal medicine company, some medical units, and purchased by the market. They were identified as Hawthorn and Bitter Hawthorn.
