目的对紫雀花药材质量标准进行初步研究。方法根据《中国药典》2015版第四部(通则)测定了紫雀花的水分、灰分、酸不溶性灰分、水溶性浸出物及异黄酮含量。结果紫雀花水分含量为80.28%~83.93%,总灰分为9.71%~12.04%,酸不溶性灰分为6.21%~9.13%,水溶性浸出物为19.61%~24.69%,异黄酮含量为0.32%~0.51%。结论该研究为苗药紫雀花质量标准的制定奠定基础,也为其合理开发利用提供参考。
Objective To study the quality standard of medicinal materials of violet flower. Methods The water, ash, acid-insoluble ash, water-soluble extract and isoflavone contents of purple violet flower were determined according to the fourth part of Chinese Pharmacopoeia (2015 Edition). Results The results showed that the water content of purple violet flower was 80.28% -83.93%, the total ash content was 9.71% ~ 12.04%, the acid insoluble ash content was 6.21% ~ 9.13%, the water soluble extract content was 19.61% ~ 24.69%, the isoflavone content was 0.32% 0.51%. Conclusion This study lays the foundation for the formulation of Miao drug violet flower quality standards and also provides a reference for its rational development and utilization.
