Supercritical Extraction of Medicinal Properties from Medicinal Plants

研究了超临界二氧化碳萃取中草药的药用成分。并对超临界二氧化碳环境下米糠中维生素的提取进行了实验研究。在这两种情况下，都进行了研究，特别探讨了温度、压力和夹带剂（水、醇、酯等）对提取物质的影响。现在正在分析许多提取物的成分。研究发现，从米糠中可提取出相当数量的甘油三酯。

Using supercritical carbon dioxide extraction of medicinal properties from Chinese herb plants was studied. Also, experiments were conducted to extract vitamins from rice bran in the supercritical carbon dioxide environment. In both cases, studies were made, in particular, to explore effects of temperature, pressure and entrainers (water, alcohols, esters etc.) on the materials extracted. Compositions of many extracts are now being analyzed. It was found out that a considerable amount of triglycerides was extracted from rice bran.
