The Chinese Pharmacopoeia (2015) records that Eucommia nourishes the liver and kidneys, strengthens the muscles and bones, and calms the fetus, and is used for liver and kidney deficiency, lumbar and knee pain, muscles and bones weakness, dizziness and dizziness, pregnancy blood leakage, and fetal movement. Traditionally, Eucommia mainly uses the bark as medicine, and the tree needs to reach a certain age before it can be peeled, however, the trunk of Eucommia needs to be peeled after an interval of 3~4 years before it can be peeled again, and if the maintenance measures of Eucommia are insufficient after peeling, it is easy to cause the peeling tree to die, thus causing a great waste of Eucommia resources and seriously affecting the sustainable development of Eucommia resources.
The leaves of Eucommia spp. are harvested in summer and autumn every year when the branches of Eucommia spp. are flourishing, and are obtained after drying. The Chinese Pharmacopoeia (2015) records that Eucommia leaves are effective in nourishing the liver and kidney and strengthening the tendons and bones, and are used for liver and kidney deficiency, soreness of the waist and knees, impotence of tendons and bones, dizziness and dizziness. Studies have shown that the effective active ingredients contained in Eucommia leaves mainly include chlorogenic acid, flavonoids, cyclic enol ether terpenoids, polysaccharides, polyphenols, phenylpropanoids, lignans and other compounds, which are basically the same as the active ingredients of Eucommia bark and have basically the same pharmacological effects, with the effects of lowering blood pressure, regulating blood lipids, preventing osteoporosis, lowering blood sugar, sedating and anti-fatigue, etc., and have wide applications in the food and pharmaceutical industries It has a wide range of applications in the food and pharmaceutical industries. Compared with eucommia bark, eucommia leaf has the characteristics of abundant source, strong regeneration and recycling ability, and reasonable harvesting will not cause damage to eucommia resources. In recent years, scholars have conducted a lot of researches on the efficacy of Eucommia leaf in order to replace Eucommia bark in practical applications, which is of great significance to promote the sustainable development of Eucommia resources. At present, the health food products which use Eucommia spp. as the main raw material include Eucommia leaf capsule, Eucommia leaf beverage, Eucommia leaf tea and Eucommia leaf wine.
Eucommia gum has many unique properties and functions, and is a natural biological material with special functions. It is widely used in automobile, ship, aerospace, chemical and other manufacturing industries. The application scope of eucommia gum has been further expanded in the fields of plastic modification, self-healing material manufacturing and thermoplastic elastomer preparation through modification and blending technologies.
However, due to the constraints of various factors, the production cost of eucommia gum remains high. According to Phytobridge, it is mainly affected by three factors: Firstly, the development of comprehensive utilization system of Eucommia is uneven, and the high-value development of Eucommia resources needs to be further deepened; secondly, the efficient extraction technology of Eucommia gum needs to be further improved and perfected; thirdly, the national restriction that Eucommia and Eucommia leaves cannot be used as food materials directly restricts the development of Eucommia food series, and closes the door for Eucommia foods with Eucommia leaves and bark as raw materials to enter the It also becomes the main bottleneck that affects the cost of Eucommia gum.
Why can't the raw materials be "the same source of medicine and food" become the main bottleneck of cost reduction of eucommia gum? According to the industrialization mode of "three-stage development", the active ingredients of the leaves and bark of Eucommia globulus should be extracted first, and then used in the production of Eucommia gum. The extracts of Eucommia leaf and bark can be separated and extracted as active ingredients for drug manufacturing, and can be used in large quantities to develop a series of health foods and functional foods, as well as dietary supplements fo...
