Objective To study the extraction technology of the polysaccharides from Sporophyll of Undaria pinnatifida Suringar and find out the optimum extraction condition.Methods The extraction technology was studied by the orthogonal design.Results The optimum extraction conditions were to add 50 times of water to the Undaria pinnatifida Suringar material at 90℃ for 4 hours.Conclusion This optimum extraction technology based on the orthogonal design was confirmed by the experiment and was available in the future research.

With the establishment of modern traditional Chinese medicine (TCM) as an oncology discipline, it has made great development and progress in the prevention and treatment of tumors. As a result, a number of academic thoughts and viewpoints have emerged. In the tumor field of TCM, the current representative theories include the theory of strengthening the body and treating cancer, the theory of treating from the membrane, the theory of surviving with tumor, the pathogenesis theory of cancer virus, the theory of consolidating the root and clearing the source, and the theory of regulating qi and detoxing. In TCM oncology, a large number of results have been achieved in the research of the thoughts of famous TCM doctors. However, discussions on these thoughts together are relatively few. This article summarizes and studies the above innovative theories from the aspects of academic connotation and clinical application to provide new ideas for further guiding the clinical practice of TCM oncology.
