Is the project of extracting heparin sodium from pig small intestine feasible?
Heparin sodium is an important biochemical drug, clinically used to treat acute myocardial infarction and viral hepatitis. Combined with ribonucleic acid, it can increase the efficacy against hepatitis B. Combined with chemotherapy, it helps prevent the metastasis of cancer cells. In addition, it also has the effect of preventing thrombosis. The production of heparin sodium falls short of demand, and the gap in the international market is extremely large. The intestinal mucosa from about 2000 pig small intestines after processing the casings can produce 1 kg of heparin sodium, worth about 22000 yuan. Therefore, using this by-product, pig small intestine mucosa, to produce heparin sodium, its value

A Detailed Guide to the Extraction and Processing Methods of Sweet Potato Starch
Sweet potatoes can be divided into two types: fresh sweet potatoes and dried sweet potatoes. Starch production from fresh sweet potatoes generally belongs to rural manual production, while sweet potato starch factories mostly use dried sweet potatoes as the starch raw material, so it belongs to industrial production. 1. Starch production from fresh sweet potatoes has the following process flow: raw material selection - washing - crushing - grinding and filtering - slurry blending - skimming the vat and settling the vat - skimming the slurry - removing the starch - drying. The production process is as follows: (1) Raw material selection: Because sweet potato varieties differ, their quality and starch content also differ. Even for the same variety, in different producing areas,

Success in Extracting Highly Effective Anti-Cancer Substance from Cloned Yew
Sichuan University professor demonstrates unique plant transgenic cloning technology, with the next step focused on anti-cancer plants. "We have already used transgenic cloning technology to successfully clone two plants with different genes, and the next step is to apply this technology to cloning the anti-cancer drug paclitaxel." Recently, Professor Wang Li from the Plant Research Laboratory of the College of Life Sciences at Sichuan University showed reporters a transgenic cloning technology little known to outsiders. A plant cloned from a leaf. In the laboratory, Professor Wang pointed to a green plant about 20 cm tall and said: "

Study and Discussion on the Extraction Process of Schisandra Extract
Hugan Tablets have the effects of soothing the liver and regulating qi, strengthening the spleen and promoting digestion, and lowering serum alanine aminotransferase. They have significant therapeutic effects on chronic hepatitis, viral hepatitis, persistent hepatitis, and early-stage cirrhosis. This product was originally a variety listed in the ministerial and provincial standards, and was later included in the 1995 edition of the Chinese Pharmacopoeia. Its testing items added "determination of schisandrin B content," but no provisions were made for the extraction process of Schisandra extract. If the Schisandra extract is still extracted according to the original material process, the extraction of schisandrin B would be unreliable. For this reason, based on the properties of schisandrin B, we designed tests using the same method with different concentrations

Tips for Extracting Honey by Spinning: Suitable for Honey Harvesting in All Four Seasons
The main economic benefit of beekeeping comes from extracting honey by spinning. As the seasons change throughout the year, the methods of honey extraction also differ. In the Yangtze River basin, the basic principles for honey extraction are: early in spring, frequent in summer, steady in autumn, and stop in winter. 1. Early in spring. After the beginning of spring, the queen bee begins to lay eggs, worker bees go out to forage, and their enthusiasm for nurturing young bees rises day by day; especially for Chinese bees (Apis cerana), when the temperature is just turning warm but still cold, they fly around searching and collecting scattered nectar. They generally produce their first batch of mature honey around the end of March. Apart from feeding young bees and

What are the extraction methods for the active ingredients of reishi mushroom?
The extraction methods for the active ingredients of reishi mushroom are determined by the properties of those active ingredients. The main active ingredients of reishi mushroom include reishi polysaccharides, ganoderic acids, adenosine, ergosterol, saponins, purines, pyrimidines, alkaloids, lactones, and so on. Most of these ingredients are soluble in hot water, but among them ganoderic acids, saponins, ergosterol and other components have low solubility in hot water while their solubility in ethanol is very high. From an economic perspective, ethanol extraction is costly and not very cost-effective. 1. Hot water extraction method: crush the reishi mushroom into pieces 0.5-1 cm in size

What are some practical tips for extracting honey by spinning the combs in the four seasons?
The main economic benefit of beekeeping comes from extracting honey by spinning the combs. As the seasons change through the year, the method of spinning honey also differs. Taking the Yangtze River basin as an example, the basic principle of spinning honey is: in spring be early, in summer be frequent, in autumn be steady, in winter stop. 1 In spring be early. After the beginning of spring, the queen bee begins to lay eggs, the worker bees go out to forage, and their enthusiasm for rearing the young rises day by day; especially the Chinese bee (Apis cerana), when the temperature turns warm but still cold, flies about searching and collects scattered nectar.
