中药及植物提取Herb & Plant Extraction

中药及植物提取Herb & Plant Extraction

世界上大约有50万种高等植物，其中大约7万种是植物性药物的基础。

在中药及植物提取物的加工过程中，为了有效提取价值组分，并保留其活性，需要采用不同的、具有针对性的加工工艺。一般情况下，它们是通过浸渍(用水或乙醇)或渗漉(用水或乙醇)获得的。水溶性(亲水性)成分用水萃取，脂溶性(亲脂)组分是用醇或其它溶剂从植物的特定部分提取。华鼎的离心分离方案广泛应用于加工过程中。

There are some 500,000 species of higher plants around the world, of which around 70,000 serve as a basis for plant- based drugs. In the process of processing herbs and plant extracts, in order to extract the value of ingredients effectively and retain their activities, various targeted process are required. Generally, they are obtained by maceration (extraction to equilibrium with water or alcohol) or percolation (extraction to exhaustion with water or alcohol). Water-soluble(hydrophilic) constituents can be extracted with water, whilst fat-soluble (lipophilic) constituents are extracted from a particular part of the plant with alcohol or other solvents. Centrifugal separation solutions from Huading Separator are widely used in these processes.
