Analysis method
The main qualitative analysis methods are TLC, IR and UV. In addition, NUCLEAR magnetic resonance (NMR), nuclear magnetic resonance (NMR) and mass spectrometry (MS) are often used to identify the structures of capsaicin and distinguish their homoloids. The commonly used quantitative analysis methods include Kjeldahl method, FAO ultraviolet double colorimetric method, key blue colorimetric method and key sodium acid-sodium nitrite colorimetric method. The chilliness index of each homology of capsaicin has a big difference. However, the above methods can only measure the overall composition of capsaicin and cannot quantify the major chilli substances respectively. Therefore, the chilli and its products cannot be quantitatively analyzed and evaluated more accurately. The above information about natural capsaicin's pharmaceutical profile, physical and chemical properties, pharmacological action, plant morphology, etc., has been edited by Ding.
use
1. Biological control
A. The rat repellent with capsaicin as the main component of green grain storage had good repellent effect on the rats in rural grain storage. The repellent containing 1% capsaicin could keep the repellent effect for more than 5 months.
B. The stimulation of capsaicin for protection of cable and cable will have a repellent effect on animals. It can be used as a functional additive for anti-rat cable sheath plastic in the cable and cable industry; When used in PVC, PE and other plastics, it can prevent rats and termites from damaging the products by eating. Antifouling coatings biological antifouling coatings made from the repellent properties of capsaicin can be applied to the parts of ships and Marine buildings in contact with seawater, which can effectively prevent the attachment of Marine organisms and the aggregation of aquatic organisms on ship hulls. At present, capsaicin has replaced organic tin as a new antifouling paint for ships and Marine buildings. D. Capsaicin, a biological pesticide, can be used as a new green pesticide in the field of biological pesticides. It has good effects of contact killing and repellent, and can achieve the characteristics of high efficacy, long efficacy and degradation in crop pest control, and is a new environmental biological pesticide.
2. Medical cosmetology A. Medical capsaicin has significant effects on neuropathic pain, rheumatoid arthritis, fresh cowhide, psoriasis, acne, baldness and so on. Analgesia is one of the most mature applications in capsaicin research. Capsaicin can also be used in the prevention and treatment of cardiovascular and cerebrovascular diseases, in addition, capsaicin can also prevent and treat peptic ulcer and respiratory diseases, and has a special effect of weight loss, anti-fatigue and auxiliary drug addiction. B. Cosmetology can be used as raw materials for the production of cosmetic skincare products for the improvement of the skin quality of the face and arms, but different parts should pay attention to the difference in concentration.
3. Other areas
A. military capsaicin has good tear effect, can cause human body strong physiological response, make the person produces symptoms such as cough, vomiting, tears, or even lost, but non-toxic side effects, so the military made tear gas, and tear gun and defense weapon of main raw materials, in the United States, Japan, Germany and southeast Asia and other countries have been widely used. Capsaicin is also used as a personal defense weapon and as a tool to subdue lawbreakers.
B. Food additives can be used in the processing of all kinds of spicy food in food workers, including all kinds of spicy fat food, daily seasoning, spicy sauce, baked food, etc. In addition, capsaicin has strong antibacterial and bactericidal properties, and has certain inhibitory effects on bacteria, fungi and yeast, so it can be used as a potential food preservative.
