目的:建立竹沥半夏的质量标准。方法:对竹沥半夏进行性状鉴别、显微鉴别和薄层鉴别;对竹沥半夏进行杂质测定,包括水分、灰分、浸出物和白矾含量;采用高效液相色谱对竹沥半夏中的姜辣素类成分(6-姜酚、8-姜酚、6-姜烯酚和10-姜酚)及核苷类成分(尿嘧啶、黄嘌呤、鸟苷、肌苷和尿苷)进行分析。结果:薄层色谱斑点清晰,分离度良好;拟定竹沥半夏水分不得超过8.8%,总灰分不得超过4.5%,酸不溶性灰分不得超过0.2%,按干燥品计,水溶性浸出物不得少于11.4%,醇溶性浸出物不得少于1.1%,按干燥品计,含白矾以含水硫酸铝钾[KAl(SO_4)_2·12H_2O]计,不得超过8.7%;竹沥半夏中姜辣素类成分含量较低,只可定性,无法定量;5种核苷总含量不超过0.02%,含量较低,因此不作为制订质量标准的依据。结论:初步建立了竹沥半夏的质量标准。
Objective: To establish ZhuLi Pinellia quality standards. Methods: The traits of Chuxiong Pinellia were identified, microscopically and thinly discriminated. The impurities of Chuxiong Pinellia were determined, including the content of water, ash, extract and alum. High performance liquid chromatography (HPLC) (6-gingerol, 8-gingerol, 6-shogaol and 10-gingerol) and nucleosides (uracil, xanthine, guanosine, inosine and uridine) analysis. Results: The TLC spots were clear and the separation was good. The water content of Pizhong Pinellia ternata was less than 8.8%, the total ash content 4.5% and the acid-insoluble ash content 0.2%. According to the dried products, the water-soluble extracts should not be less than 11.4% alcohol-soluble extract shall not be less than 1.1%, in terms of dry goods, with alum to aqua potassium aluminum sulfate [KAl (SO4) _2 · 12H_2O], shall not exceed 8.7%; Zhu Le Banxia gingerol Low content of ingredients, only qualitative, quantitative; 5 nucleosides total content of not more than 0.02%, low content, therefore not as a basis for the development of quality standards. Conclusion: The quality standard of Zhuli Pinellia was initially established.
