结果在煎煮过程中双酯型生物碱溶解并发生水解反应 ，而脂类生物碱则难溶于水。
Results The results showed that the DDAs were solved and reduced by hydrolysis reaction, and the lipo-alkaloids were difficult to be soluted in the Decoction.
方法：采用酸性染料比色法测定附子总生物碱含量，反相高效液相色谱法测定双酯型生物碱含量，蒽酮-硫酸法测定多糖含量。
METHODS: The contents of total alkaloids, diester diterpenoid alkaloids and polysaccharides were measured by acid dye colorimetry, HPLC and sulphuric acid-anthrone colorimetric method respectively.
生川乌炮制后生物碱大多数由双酯型水解转化为单酯型，水解反应最容易发生的位置在C8位，水解反应的类型是烷氧键发生断裂的酯的碱性水解。
After processing of crude aconite roots, most of the diester diterpenoid alkaloids converted to the monoester form, while C8 was the major location for such reaction. It is a ty…
