当归除用生品外,还多以制品人中药复方,炮制方法有20余种。当今常用的有酒、土、炙炭等品种。当归经炮制后挥发性成分大部分散失。药理实验表明其水溶物与脂溶部分有相似的生物活性。去挥发油的水提液经药理实验证明有显著的“补血”作用。为了有助于对当归炮制机理的研究,我们测定了生品及三种炮制品饮片、煎液中的10种无机元素。
In addition to using raw materials, Chinese angelica is also used to produce Chinese herbal compound, and there are more than 20 kinds of methods for processing. Nowadays, there are varieties of wine, earth, loquat charcoal and so on. Most of the volatile components were lost after processing. Pharmacological experiments showed that the water-soluble and fat-soluble fractions had similar biological activities. The aqueous extract of volatile oil was proved to have a significant “blood” effect through pharmacological experiments. In order to facilitate the study of the mechanism of the processing of Angelica sinensis, we determined 10 inorganic elements in the decoction and decoction of the raw product and the three processed products.
