　　Recently, the Di Duolong research group of the Northwest Plant Resources Chemistry Key Laboratory of the Chinese Academy of Sciences developed a new technology from the Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences, which was developed by De Duolong. The reporter learned that he has successfully separated and prepared. At present, the technology has passed the appraisal of scientific and technological achievements in Gansu Province and has been industrialized.

　　China is a big country of deer, and Gansu is the largest red deer breeding base in Northwest China. In 2011, an academic report on the research of peptides in the bloodstream of Northeast sika deer inspired Didoron. The main functional component of deer blood is deer blood peptide, which can lower blood pressure, enhance immunity and have anti-fatigue effects. no. The biological activity of deer blood peptide is different, and the molecular structure and biological activity are also very different. "Back to the laboratory, the research team analyzed the blood of the red deer. Dr. Liu Yongfeng from the laboratory told reporters: "So far, the laboratory has been mainly studying plants. Plants are small molecular compounds with simple structure and easy separation. Peptides are high molecular compounds. The method of separating them is the biggest challenge. In subsequent experiments, the research team used complex enzymatic hydrolysis technology and multi-stage continuous separation and purification technology of porous adsorbent materials as the core technology to obtain high-purity and biologically active deer blood peptides. Extracted successfully. This technology has a higher process yield (80%), higher product purity (polypeptide content can reach 65%-98%), lower production costs, and higher safety (the entire production process). Environmental protection). The scientific and technological achievements of Gansu are determined as: the research results have reached the international advanced level of similar research. After separating and preparing the deer blood peptide, the research did not end there. Instead, the deer blood peptide effervescent tablet was developed for the market and the scientific research results were transformed into the final product, еTatataka said. Yang Shuting, chairman of Gansu Nanshan Biotechnology Development Co., Ltd., said that with 100% deer blood every day, an industrial production line for extracting deer blood peptides will be built by the end of this year.
