Chemical composition and pharmacological activities of the Phellodendron chinense Schneid

Phellodendron chinense Schneid(P.chinense),as a traditional Chinese medicine,is commonly used in clinical practice.It has the effects of drying dampness,clearing heat,detoxifying,purging fire,and reducing swelling.Its main chemical components are flavonoids and alkaloids,which have various pharmacological effects such as lowering blood sugar,lowering blood pressure and immunosuppression.With the continuous development of modern science and technology,the research on P.chinense Schneid has increased.This study reviews the chemical components and pharmacological effects of P.chinense Schneid,and provides reference for its further research and development.

A new sesterterpenoid from the fruits of Phellodendron chinense var.glabriusculum Schneid

A new sesterterpenoid phellogine was isolated from the fruits of Phellodendron chinense var. glabriusculum Schneid. Its structure was elucidated on the basis of spectral analysis.

黄柏产地趁鲜加工工艺及其可行性研究

为了优化黄柏(Phellodendron chinense Schneid.)趁鲜加工工艺,并验证其可行性,采用正交试验设计,考察工艺参数对黄柏丝质量的影响,并对趁鲜加工黄柏丝进行质量评价。结果表明,初干温度对黄柏丝的质量存在显著影响;初干温度、初干程度、复干温度均对黄柏丝加工效率有极显著影响。综合考虑黄柏丝质量、干燥时长、能耗,最适加工工艺为切丝前自然晾晒或45℃干燥至含水量43%~50%时切丝,而后45℃干燥至含水量12%以下。趁鲜加工的黄柏丝性状、水分、总灰分、浸出物、小檗碱、黄柏碱含量均符合《中华人民共和国药典》要求,质量与市售黄柏丝无显著差异,优于传统加工黄柏丝。因此,川黄柏产地趁鲜加工取代传统方法是可行的。
