What is the reflection on the extraction and separation of baicalin from scutellaria baicalei
The following is a possible reflection on the extraction and separation of baicalin from scutellaria: ** 1. In terms of productivity ** 1. ** Pretreatment of raw materials ** - If the coarse powder was not soaked or the powder was not completely soaked, it would cause the baicalin to not be fully dissolved from the raw materials, affecting the final yield. In the follow-up experiments, it was necessary to ensure the pre-treatment of the raw materials and ensure sufficient soaking time so that baicalin could be dissolved into the extraction solution as much as possible. 2. ** Sedimentation Stage ** - If the settling time was short, the product would be lost due to incomplete settling. The settling time should be arranged reasonably, and the experimental operation could be optimized, such as stirring properly before settling, to improve the settling effect and thus increase the yield. 3. ** pH-adjustment ** - If the temperature was not well controlled when adjusting the pH. It would affect the stability and extraction effect of baicalin. It was necessary to precisely control the temperature during the adjustment of the pH. A more rigorous pH-adjustment plan should be formulated before the experiment. The appropriate pH-value range should be determined according to the chemical properties of baicalin, and the operating conditions should be optimized within this range. ** 2. Operation process ** 1. ** Temperature-control ** - During the extraction process, in order to prevent baicalin from being decomposed and oxided, and to reduce the damage of the effective components, the extraction should be carried out at a certain temperature. However, there may be temperature fluctuations or inappropriate temperature settings in actual operation. He needed to improve the temperature control equipment or operation process to ensure the stability of the temperature during the entire extraction process. - When extracting and purifying flavanoids with acid and alkali-based methods, the temperature and the alkali-based method should not be too high. In the experiment, there might be situations where the control of the temperature and basicity was not precise enough. It was necessary to determine the appropriate temperature and basicity range strictly according to the chemical properties of baicalin in the subsequent operations and strictly monitor it. 2. ** Selection and combination of extraction methods ** - Different extraction methods, such as ultrasonic extraction, reverse extraction, Soxhlet extraction and cold soaking, had their own advantages and disadvantages. A single method might have limitations. For example, if only one extraction method was used in the experiment, the best extraction effect might not be achieved. In the subsequent experiments, the optimal combination of various extraction methods could be considered to improve the yield and purity of baicalin. ** 3. Detection and Judgment ** 1. ** Accuracy of reaction judgment ** - When conducting experiments to determine baicalin, such as the reaction of hydrogen chloride-magnesite powder, the reaction of titanium-citric acid, and the reaction of aluminum dioxide, the details of the operation steps may affect the accuracy of the determination results. For example, factors such as the order of addition of reagents, the amount of addition, and the reaction time needed to be strictly controlled. Otherwise, false positive or false negative results might occur, affecting the accurate judgment of whether the extracted product was baicalin. 2. ** Determination of content ** - Although there were some conventional methods for the determination of baicalin, these methods might have some errors or were not simple enough. The content determination method needed to be optimized, such as selecting a more suitable constant volume solution and improving the analytical conditions, so as to improve the accuracy and reliability of the determination results.

Paris Olympic opening ceremony scene
From the feedback of some netizens, the opening ceremony of the Paris Olympics had some scenes that were considered "eye-catching". For example, the opening scene was abrupt, and the contestants suddenly appeared after the fireworks. The free audience on the terrace was messy in the picture, and the camera shots of the singing guests were often blocked by the fountain. The athletes stood on the chairs, and the water spray device was like a square fountain, which looked simple and crude. Some contestants seemed to pass by in a hurry, and they were even teased that they didn't have enough boats, so they had to build boats. The whole scene gave people a feeling of being busy but not knowing what they were busy with. It was more abstract. While watching the Olympics, you can also read the wonderful novels related to the Olympics!

Is there any pain in the liver? What medicine should I take?
The use of drugs for pain in the liver area should be determined according to the cause of the pain. 1. If it was pain in the liver area caused by acute and chronic liver disease, oral liver-protecting drugs, such as compound licorice acid tablets, polyene Phosphatidylcholin, licorice acid diammine enteric-coated capsules, etc., should be taken. Regular liver function and liver color ultrasound should also be checked. If the large number of copies of the liver virus causes damage to the liver cells, the patient with chronic liver disease can take oral administration of Entecavir, and the patient with chronic liver disease can take oral direct anti-viral drugs such as sofobuvir and velpatasvir. 2. When a liver Abscess causes pain in the liver area, oral medication is often ineffective, and intravenous antibiotics are needed, such as methonidazuron and third-generation cephem antibiotics. When the pain is severe, oral painkillers, such as tramadol slow-release tablets, can be used. 3. If a patient with liver cancer has pain in the liver region, painkillers such as tramadol and morphines can be used after eliminating the rupture and bleeding of the liver cancer nodes. 4. Pain in the liver area caused by gallstones and chronic cholecystectomy could be treated with anti-inflammatory and choleretic drugs, such as ursodesoxidocholic acid, anti-inflammatory and choleretic tablets, etc., while acute cholecystectomy was often complicated with bacteria infection, which required intravenous anti-inflammatory drugs. 5. Liver cancer causes pain in the liver area, and you may need to take liver-protecting drugs, such as reduced glutathion, bicyclol, licorice acid, and dexuronolactone. You also need to treat the cause of liver cancer, such as Entecavir, Sofabuvir, etc. 6. Pain in the liver area caused by infection requires the use of antibiotics for treatment. Commonly used drugs include cephem antibiotics, penicillins, and anti-anaerobia drugs. If necessary, intravenous infusion of antibiotics is required for treatment. Commonly used drugs include Cefoperazone, Amethyst, Metronidazle, etc. For pain in the liver region caused by malignant tumor, surgery was performed after relevant examinations were completed. Later, according to the pathological results, chemotherapy and targeted drug therapy were given. The chemotherapy drugs included fluralin, cisplatins, etc., and the targeted drugs included sorafenib, lenvatini, etc. The pain caused by tumor could be treated with oral painkillers, such as fluralin, tramadol, painkillers, etc. However, pain in the liver area should not be self-administered. They should go to the hospital for diagnosis and treatment first. After the cause of the disease is confirmed, the treatment should be standardized. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
