| 中药材药物成分 Ingredients of medicinal herbs 中药材种类繁多，来源广[2]泛，各种药材又具有多种化学成分，按照其药理作用和组成性质，概括起来中药材的成分可分为以下几方面： There are many different kinds of Chinese herbal medicine, wide source [2], a variety of medicinal materials with a variety of chemical composition, according to its pharmacological effects and properties of traditional Chinese medicine composition of generalizing can be divided into the following several aspects: ①有效成分 即具有生物活性，发挥主要药效的物质，如生物碱、甙类、挥发油。 The active ingredient is the biological activity, the substance that plays the main effect, such as alkaloids, glycoside, and volatile oil. ②辅助成分 本身没有特殊疗效，但能增强或缓和有效成分药效作用的物质。如洋地黄中的皂甙可帮助洋地黄甙溶解或促进其吸收。 The auxiliary components themselves do not have special effects, but they can enhance or mitigate the effects of effective components. The saponins in the ocean can help the digitoxin dissolve or promote the absorption. ③无效成分 指本身无效甚至有害的物质，往往会影响浸出效果、制剂稳定性、药效等。 The term "invalid" is a substance that is not valid or even harmful, which can affect the effect of leaching, the stability of the preparation and the efficacy of the drug. ④组织物质 构成细胞的不溶物，如纤维质、栓皮等。 The insoluble substance of a cell, such as fiber, emboli, etc. 大多数中药制剂是复方，中药复方的临床疗效通常体现 在复方配伍的综合作用上，其处方的组成几味至几十味药不等，成分复杂。浸取就是要尽量提出发挥药效的成分，并尽量避免浸出过多的无效甚至有害的物质，但随着中药科学的发展，“无效”和“有效”的界限并非一成不变，在不同的方剂中可能会发生变化。某些过去认为是无效的成分，如今却发现它有生物活性，应根据不同组方的成分变化，确定浸取过程中的最佳提取工艺。 Most of the Chinese native medicine preparation is complex, the clinical efficacy of Chinese medicine compound is usually reflected in compound compatibility on the combination of several smell or taste as well as composition of the prescription medicine, complicated composition. Leach is to put forward play efficacy components as far as possible, and try to avoid excessive leaching of ineffective or even harmful material, but with the development of traditional Chinese medicine science, the boundaries of "invalid" and "effective" is not fixed, may change in different prescriptions. Some people used to think that is invalid, are now finding it has biological activity, should according to the composition changes of different formula, determine the best extraction technology in the process of leaching. |
