Embodiment 1
[0018] Freshly collected periwinkle flowers with a moisture content of 70-80% are placed in a blast chamber. Under the condition of a humidity of 75%, they are treated with 30 degrees hot air for 3 hours, and then they are placed in a storage tank. Soak the PEG6000 solution with a concentration of 20% for 10 hours. After washing off the PEG6000 solution, pass in clear water. The ultraviolet lamp is irradiated once every 30 minutes, and each irradiation is 5 minutes. There are 2 irradiations in total. The irradiation dose is 5W / m. 2 , While irradiating, use negative pressure 0.06~0.1MPa suction or positive pressure 0.1~0.6MPa suction method for stirring. The RP-HPLC method determined the content of vinblastine alkaloids in the raw materials at this time. The results showed that the content of vinblastine in the raw materials was increased by 5.6 times after this process, and the content of vincristine was increased by 2 times.
Embodiment 2
[0020] Put the periwinkle with 60% water content in the blast chamber, and put it in the 40 degree hot air for 4 hours under the humidity of 80%, then put it in the storage tank, use 15% concentration The PEG6000 solution is soaked for 12 hours, and the PEG6000 solution is washed away and then poured into clear water. The UV lamp is irradiated every 30 minutes, and each irradiation is 5 minutes, a total of 4 irradiations, the irradiation dose is 6W / m 2 , While irradiating, use negative pressure 0.06~0.1MPa suction or positive pressure 0.1~0.6MPa suction method for stirring. The RP-HPLC method determined the content of vinblastine alkaloids in the raw materials at this time, and the results showed that after this process, the content of vinblastine in the raw materials was increased by 3.8 times, and the content of vincristine was increased by 0.72 times.
