Research on Quality Standards of Fruit of Hippophae Tibetana Schlechtend / 世界科学技术-中医药现代化

ABSTRACT

This study was aimed to establish quality standards of fruit of Hippophae tibetana Schlechtend.. The medical material was identified by microscopy and thin layer chromatography (TLC). According to methods recorded in the Chinese Pharmacopoeia (2010 edition), the contents of moisture, total ash, acid-insoluble ash and alcohol-sol-uble extract were determined. The HPLC method was applied in the determination of quercetin, kaempferol and isorhamnetin content. The results showed that the microscopic characteristics of Tibetan medicine H. tibetana were identified. The TLC and content determination methods of quercetin, kaempferol and isorhamnetin were estab-lished. It was concluded that the established qualitative and quantitative methods can be used for quality control of the fruit of H . tib e tana.
