青稞红曲的质量标准研究

目的：建立青稞红曲的质量标准。方法：采用显微、薄层色谱法建立定性鉴别；参考2010年版《中国药典》（一部）相关方法测定其水分、总灰分、酸不溶性灰分和浸出物的含量；采用高效液相色谱法测定酸式洛伐他汀和内酯型洛伐他汀的含量。结果：青稞红曲的显微、薄层色谱鉴别特征明显，专属性强；青稞红曲中水分6.04%-8.78%，总灰分2.15%-2.92%，酸不溶性灰分0.23%-0.29%，水浸出物27.99%-30.17%，醇浸出物14.12%-18.51%。青稞红曲中酸式洛伐他汀含有量在0.11%-0.29%范围内，内酯型洛伐他汀在0.02%-0.08%范围内。结论：本文建立的方法操作简单、准确可靠、重复性良好，可用于控制青稞红曲质量。

Quality Standard for Highland Barley Monascus

This article is aimed to establish the method of quality standards for highland barley Monascus.Microscopic and TLC were adopted to identify Araliataibaiensis. Referring the relevant method in Chinese Pharmacopoeia (2010 edition) for the determination of its moisture, total ash, acid insoluble ash and extracts, lovastatin in acid and lactone form was determined using high performance liquid chromatography. The characteristics of highland barley Monascus in microscopic and TLC were obvious and specific. The contents in barley red yeast are: water 6.04%-8.78%, total ash 2.15%-2.92%, acid insoluble ash 0.23%-0.29%, water extracts 27.99%-30.17%; alcohol extracts 14.12%-18.51%. The ranges of lovastatin in acid and lactone form are 0.11%-0.29% and 0.02%-0.08%, respectively. The established method is simple, accurate, reliable and duplicable, and can be used to control the quality of highland barley Monascus.
