摘要
分子蒸馏技术是一种新型高效的液-液分离技术,同时也是精制和保护中药有效成分的一种有效途径,特别适用于高沸点、热敏性及易氧化物的分离和纯化。本文总结了近年来中山大学关于中药油精制的分子蒸馏技术研究,并提供了3个案例:米糠油中植物甾醇的制备研究、广藿香油有效成分的分离纯化以及肉桂油中反式肉桂醛的富集,通过这些典型案例分析,作者探讨了分子蒸馏技术在中药油精制中的应用优势及在中药质量控制中的地位。
Molecular distillation is not only an innovative liquid-liquid separation technique but also a good approach for refining and protecting active tion for materials with high boiling point, fled out by the Sun Yat-sen University components of Chinese medicine. It is suitable for separation and purificaheat-sensitivity or easy oxygenation. In this paper, the research works caron the molecular distillation technology have been summarized. The three cases are the study on preparation of phytosterol in rice bran oil, on separation and purification of active ingredients in patchouli oil and on enrichment of trans-cinnamaldehyde in cinnamon oil. These classical cases were studied to illustrate the practical advantages and status of molecular distillation in Chinese herbal oils refining and quality control of Chinese medicine.
