老鹰茶总黄酮颗粒剂的制备工艺及质量标准
Preparation Technology and Quality Standard of Total Flavonoids from Laoying Tea
摘要
Abstract
[Objective] To study the preparation technology of total flavonoids from Laoying tea granules and to establish methods for its quality control.[Method] Water solution of Laoying tea was obtained under a given extraction method.Extract powder of total flavonoids was obtained by macroporous resin.Effects of auxihary materials on the compactibility,hygroscopicity,bulk density and slope of repose were investigated,so as to screen the optimal auxiliary materials and prescriptions.Total flavonoids from Laoying tea granules were qualitatively analyzed by thin layer chromatography.Content detection and methodology study of total flavonoids were carried out by spectrophotometric method.[Result] The optimal prescription of total flavonoids from Laoying tea granules were as follows:30 g powder of total flavonoids,20 g mannitol and 10 g lactose.The optimal technology was 1∶1.0 g/g raw materials to auxiliary materials ratio,70％ ethanol as wetting agent and 60 ℃ baking temperature.The standard curve of total flavonoids was A =22.100c + 0.001 0 (R2 =0.999 86).The dissolubility,moisture content and grain size all met the requirements.Content of total flavonoids was 134.4 mg/g,the added recovery rate was 96.94％.[Conclusion] This technology is simple and feasible;and the quality was stable and controllable.关键词
