The technology of collecting and extracting scorpion venom from cultured scorpion

Scorpion is a valuable traditional Chinese medicine in China. The reason why it can be used in medicine mainly depends on scorpion venom. This scorpion venom has obvious spasmodic effect on people and is called "liquid soft gold". So how does scorpion venom come into being? Where is the scorpion hidden? How can scorpion venom be skillfully collected without pain? What problems should be paid attention to in the process of extraction? These questions will be answered one by one in the film.

Note: at present, some scorpion farmers, under the misguidance of some seed sellers, have a tendency to understand scorpion venom, thinking that scorpion breeding is mainly to extract scorpion venom, and one gram of dry scorpion venom can be extracted for every 5 kilograms of live scorpion, which can make a profit of 10,000 yuan. It can be extracted continuously every 2 weeks, and the economic benefit is very considerable. Sellers sell scorpion venom under the banner of recycling scorpion venom after planting. In fact, plumbing is a hoax. In the current situation, there is not a simple equipment for the determination of pure fake scorpion venom in China, which is also difficult for general scientific research institutions to determine, even if extracted, it will be unable to recover for various reasons. Moreover, the scientific and technological level of domestic use of scorpion venom is not high, and there are still difficulties in sales. Therefore, scorpion farmers should treat this special aquaculture industry correctly. Of course, with the deepening of research, scorpion venom will play an important role in the prevention and treatment of diseases. Related knowledge: when enraged, scorpions expel venom from the poison sac out of defensive or attacking instincts. The collection of scorpion venom is based on this principle. There are three common methods to collect scorpion venom: tail-cutting method, artificial stimulation method and electric stimulation method. Among them, the electric excitation method is the most advanced and scientific one. Electric development stimulation scorpion venom extraction method: this is a method of extracting scorpion venom which combines the advantages of tail-cutting method and artificial stimulation method. It not only has a faster speed, but also has a higher amount of poison collection, and does not affect the processing of scorpion venom, so it is usually used in practice. This method can also be used to collect many kinds of animal toxins such as entertaining ants, bees, spiders and so on. The method of electric stimulation is to stimulate the tail segment of scorpion with high frequency and weak current to contract the glandular muscle of scorpion venom capsule and promote its detoxification. The multi-purpose instrument for pharmacological and physiological experiments can be used to collect poison, and the frequency of continuous induction electrical stimulation can be adjusted to 128 hertz with a voltage of 6 ~ 8 volts. Use one electrode to hold one of the scorpion's tentacles, and then use a metal clip in the scorpion's rear abdomen section 5, with the other electrode constantly contact with the metal clip, the venom will be discharged. If there is no reaction, drop a few drops of normal saline on the place where the electrode is in contact with the scorpion body, and then collect the venom from the tail thorn with a small beaker of 50ml, and vacuum dry or freeze dry as soon as possible. The venom extracted by electrical stimulation changed successively, the first drop of venom was clear and transparent, then milky white, and finally the venom was strong. By using this method, the single scorpion has a large amount of detoxification. The female scorpion can take 0. 5% at a time. About 3 mg, male scorpion can take 0. 5% at a time. About 2 milligrams. The amount of scorpion detoxification is also related to the ambient temperature. When the ambient temperature is high, the scorpion body is in a state of excitement, the amount of detoxification increases accordingly, and vice versa. Processing method of scorpion venom: scorpion venom liquid is easy to deteriorate at room temperature, and it can only be preserved for about half a month in the refrigerator. Therefore, it must be processed into dry poison powder in order to be preserved and used for a long time. The processing method is as follows: the liquid scorpion venom is first frozen in the refrigerator. Freeze and move into the vacuum dryer, put an appropriate amount of calcium oxide at the bottom of the dryer as the desiccant, the desiccant is covered with four layers of new gauze, the gauze is placed with a beaker filled with scorpion venom, and then the air is pumped by a vacuum pump. In the process of pumping, we should pay attention to observe that if a large number of bubbles are found on the surface of scorpion venom, stop pumping for a moment until it is basically dry, and then rest for 24 hours, so that scorpion venom is completely dried and becomes particles of different sizes. This is the raw dried powder of scorpion venom. Scrape off the dry poison powder and pack it into vials, dissolve wax, seal, label and indicate the preparation date and weight of scorpion venom powder. Wrap it with opaque black paper and store it in a refrigerator of-5 ℃. It will not deteriorate within 5 years.
