答:甙类化合物是由糖或糖的衍生物与甙元通过甙键相连的物质,其溶解性能随糖的数目、种类及甙元的结构而不同;在稀酸和酶的作用下能水解生成糖和甙元;含甙类中药本身通常含有相应的分解酶,在一定温度、湿度下即可发生酶解。很多含甙类中药不宜提前用冷水浸泡。为避免大部分甙被酶解损失,一般浸泡时间要根据药材性质而定,对花、叶、茎类为主的,可浸泡20～30分钟,以根、根茎、种子、果实等为主的,可浸泡60分钟。
A: Anthraquinone compounds are substances that are linked by a hydrazone bond from a sugar or a derivative of a sugar, and the solubility of the anthraquinone compound varies depending on the number and type of sugars and the structure of the aglycone; they are hydrolyzed by the action of a dilute acid and an enzyme. Produce sugar and aglycon; Chinese medicine containing glycosides usually contains the corresponding decomposing enzymes, which can be enzymatically digested under certain temperature and humidity. Many Chinese herbal medicines containing germanium should not be soaked in cold water in advance. In order to avoid the loss of most alfalfa by enzyme digestion, the soaking time is generally determined according to the nature of the medicinal material. For flowers, leaves, and stems, it can be soaked for 20 to 30 minutes, with roots, rhizomes, seeds, fruits, etc. Soak for 60 minutes.
