Abstract

The invention provides a quality detection method for tibetan medicine rhododendron anthopogonoide and a tibetan medicine rhododendron anthopogonoide preparation. The method includes: determining the total flavonoid content in the rhododendron anthopogonoide and the rhododendron anthopogonoide preparation by ultraviolet-spectrophotometry; simultaneously determining the total quercetin content in the rhododendron anthopogonoide and the rhododendron anthopogonoide preparation in the same chromatograph by high-performance liquid chromatography; and establishing a finger-print chromatogram of flavonoids in the rhododendron anthopogonoide and the rhododendron anthopogonoide preparation by the high-performance liquid chromatography. Therefore, quality of the rhododendron anthopogonoide and the rhododendron anthopogonoide preparation can be guaranteed by detecting whether common peaks exist in the finger-print chromatogram or not, and further medication safety for patients is guaranteed. The quality detection method is stable in sample solution, high in precision and excellent in reproducibility, has certain specificity, is good in separating effect of each characteristic constituent in the finger-print chromatogram, can be used for quality detection of rhododendron anthopogonoide medical materials, and is beneficial to guarantee of safety, effectiveness, controllability in quality and good clinical effect for the tibetan medicine rhododendron anthopogonoide and the tibetan medicine rhododendron anthopogonoide preparation.

Description

technical field [0001] The invention relates to a quality detection method, in particular to a quality detection method of a Tibetan medicine rhododendron azalea and a preparation thereof. Background technique [0002] Rhododendron anthopogoniodes Maxim.et Franch is the dried flower and leaves or twigs with leaves of Rhododendron anthopogoniodes Maxim.et Franch. It is mainly used for bronchitis, emphysema, edema, physical weakness and soil discomfort, indigestion, gastroptosis, gastric dilatation, external use to treat sores. "Yuewang Medicine Clinic" records: "Treating dragons, Chiba, Bacon's disease, spleen and stomach deficiency and cold, indigestion, and acclimatization." "Qi Tie Garland" records: bitter taste, warm nature, light effect. Cure bacon's disease. "Mingshi Chapter Thirty" records: warm in nature, cure Bacon's disease, lung disease pain, hiccups. "Picture Book" records: This product was born in the shade of the mountain. The trunk is white, the leaves are...
