Preparation Of Fufang Shuanghuanglian Dispersible Tablet

Fufang Shuang huanglian dispersible tablet consisting of scutellaria, honeysuckle.forsythia suspense and Dandelion. It possess acrid-cold herbs relieving superficies, heat-clearing and detoxicating. relieve cough and reduce sputum efficiency for which influenza fever, headache have a stuffy nose, cold cough, swelling of throat, limbs ring to be tired of work. Its precise effects, drug side effects small.This study were to scutellaria,honeysuckle.forsythia suspense and dandelion extraction processes fcr the optimization; Approached dispersible tablet prescription composition, preparation crafts, quality-specification and pharmacodynamics.Using orthogonal experiment each baicalin ,chlorogenic acid and caffeic acid for the inspection targets, and optimize the extraction process.Scutellaria crashed up 40 mu, plus water to infiltrate about 0.5h, plus water decoctioned two times( the first time ,the solvent is water and the material is 8:1, and the second time .the solvent is water and the material is 6:1). decoctioned each time is 1.5h, fractionation filtered, merging two times decoctioned liquid, enrichment, to make relative density 1.10～1.20.Then the solvent is deposited by alcohol, refined, dry.Honeysuckle and forsythia suspense, plus water to infiltrate about 0.5h, plus water decoctioned two times( the first time,the solvent is water and the material is 8:1, and the second time,the solvent is water and the material is 6:1), decoctioned each time is 1n, fractionation filtered, merging two times decoctioned liquid, enrichment to make relative density 1.20～1.25(70～80 centi-degree), cold to 40 centi-degree.Then the solvent is deposited by alcohol, refined, dry.Coarse powder of dandelion, plus water to infiltrate about 1.5h, plus water decoctioned two times( the first time ,the solvent is water and the material is 12:1, and the second time ,the solvent is water...
