草豆蔻中山姜素和小豆蔻明提取工艺研究

Study on the extraction process of alpinetin and cardamonin in Alpinia Katsumadai Hayata

目的 对草豆蔻中山姜素和小豆蔻明提取工艺进行研究。方法 用95 %乙醇提取,柱色谱法分离。结果 得到晶体Ⅰ、晶体Ⅱ,经TLC、HPLC、UV、IR、NMR鉴别分别为山姜素、小豆蔻明。结论 此工艺简便,分离洗脱快速、安全,成本低并且重现性好。

Objective To study the extraction process of Alpinia Katsumadai Hayata. Method The seeds of Alpinia Katsumadai Hayata were extracted with 95% EtOH and isolated with silica gel chromatography. Results Crystal compound Ⅰ and Ⅱ were obtained. On the basis of their physical and chemical properties and analysis (IR, NMR,UV,HPLC,TLC),the compounds were identified as alpinetin and cardamomin. Conclusion The extraction process was simple, rapid and economical.
