作者研究了在贯叶金丝桃地上部分两相提取中加入表面活性剂后,其亲水亲脂平衡(HLB)与亲水、亲脂活性物质提取度的关系。该植物地上部分的亲脂性活性物质为叶绿素衍生物、胡萝卜素类等,亲水性活性物质为黄酮类、蒽类衍生物和鞣质等。乳化剂为豆油、单酸甘油酯、吐温-80、丙二醇和水。将该植物用丙二醇浸渍,待药材膨胀后加入豆油,加温至70℃左右,搅拌10min,然后加入混
The authors studied the relationship between the hydrophilic and lipophilic balance (HLB) and the degree of extraction of hydrophilic and lipophilic active substances after the addition of surfactants to the two-phase extraction of Hypericum perforatum. The lipophilic active substances of the aerial parts of the plant are chlorophyll derivatives, carotene, etc. The hydrophilic active substances are flavonoids, anthraquinone derivatives and tannins. The emulsifiers are soybean oil, monoglyceride, Tween-80, propylene glycol and water. The plant is impregnated with propylene glycol, soy oil is added after the medicine is expanded, heated to about 70° C., stirred for 10 minutes, and then added to the mixture.
