| 摘 要： | 目的:测定并考察玄参炮制前后多糖的含量变化,以探讨玄参的炮制机理。方法:采用苯酚-硫酸法测定玄参炮制前后多糖的含量。结果:生品总糖含量为64.89%,得率为9.74%;制品总糖含量为65.90%,得率为7.89%,较生品多糖得率下降了19.02%。结论:玄参经蒸制后,多糖得率降低。实验结果为探讨玄参炮制机理提供了一定的依据。

| Abstract: | Objective:To determine the content of Polysaccharides in crude and processed Radix Scrophulariae,thus to approach the process mechanism of Radix Scrophulariae.Methods:Phenol-sulfuric acid method was used to determine polysaccharides in crude and processed Radix Scrophulariae.Results:After processing,the content of polysaccharides of Radix Scrophulariae decreased from 9.74%(content of total polysaccharidesbeing 64.89%) to 7.89%(content of total polysaccharidesbeing 65.90%),decreased by 19.02% as compared with that in crude Radix Scrophulariae.Conclusion:After processing,the content of polysaccharides decreases markedly.The results provide certain evidence for approaching the process mechanism of Radix Scrophulariae. |
