黄连是毛茛科植物黄连(Coptis chinensis Franch)的乾燥根茎,收载於中国药典为中药中应用较广的一种。近年来我国学者们纷纷报告黄连和其主要成分具有强大的抗菌效用.益增黄连在现代药学上的地他。黄连中含有多种生物鹼以小蘗鹼(berberine)含量最高亦极重要.是黄连中抗菌作用的主要成分。由於小蘗鹼分了结构的特殊(能为三种互变民性体成立平衡状态而存在),所以它的物理性质和化学性质与一般生物鹼不同。这样虽使自黄连中提取小药鹼感觉方
Coptis chinensis is a dry rhizome of Coptis chinensis Franch, which is widely used in Chinese Pharmacopoeia. In recent years, Chinese scholars have reported that Rhizoma Coptidis and its main components have a powerful antibacterial effect. Yi Zeng Huang Lian has his modern medicine in the earth.

Since berberine has a special structure (which can exist for the formation of equilibrium for three kinds of interconvertibles), its physical properties and chemical properties are different from those of general alkaloids. Although this makes it possible to extract small drug bases from Huang Lianzhong,
