大家都知道,水和油混合时就分为二层,一般上层是油,下层是水,它们的性质不同。其它化学药品、中草药化学成分,虽然各有不同的性质,但他们的溶解性有的近于水,有的近于油。近于水的就疏于油,近于油的就疏于水。这种近于水的就叫做亲水性,近于油的叫做亲脂性。不同的化合物近于水或近于油的程度是会有所差异的,近水程度大的叫做亲水性强,近油程度大的叫做亲脂性强。同一个化合物只要亲水性强,亲脂性就必然弱,反之亲脂性强,亲水性必然弱。亲水性强的化合物在水中的溶解度就
As we all know, when mixed with water and oil, it is divided into two layers. Generally, the upper layer is oil and the lower layer is water. Their properties are different. Other chemicals, Chinese herbal chemical composition, although each has a different nature, but some of their solubility near water, and some near-oil. Close to the water on the neglect of oil, near the oil on the neglect of water. This near-water is called hydrophilic, near-oil called lipophilic. Different compounds close to the water or near the degree of oil will be different, the degree of near-water called hydrophilic, strong, close to the degree of oil called lipophilic strong. As long as the same hydrophilic compound, lipophilicity will inevitably weak, whereas lipophilic strong, hydrophilic inevitable weak. Hydrophilic compounds in water solubility
