【Abstract】 This study was aimed to establish the quality standard of Tibetan medicine Rhododendron Flos. According to the Chinese Pharmacopoeia(2010 edition), the moisture, total ash, acid-insoluble ash and water-soluble extracts of the material medical were identified. The microscopy and thin layer chromatography(TLC) were used to establish identification methods. The contents of hyperoside and quercitrin were determined by HPLC method. The results showed that this study had established the microscopic identification feature, TLC and HPLC determination methods of hyperoside and quercitrin. It was concluded that the established method was simple to operate with good stability and reproducibility. It can be used for quality control of Rhododendron Flos.更多还原
