Problems solved by technology

But making a general survey of the technology and preparations of the above-mentioned products, there are deficiencies: (1) Zhibai Dihuang Tablets (included in the fifth volume of Chinese medicine prescription preparations of the Ministry of Health of the People's Republic of China) its technology is: Chinese yam, dogwood, zebra Xie pulverized into fine powder; Cortex Moutan crushed into fine powder; the other four flavors such as Anemarrhena anemarrhena were extracted with water, concentrated into a thick paste, mixed with the above-mentioned three flavors fine powder such as yam, dried, pulverized, and then mixed with the fine powder of Cortex Moutan, Granulated with auxiliary materials, compressed into tablets, coated with sugar
The prescription amount of this concentrated pill is reduced by about one-third on the basis of the pill, but 8 pills are still required to be taken each time. Part of the cornus officinalis and Moutan cortex in the prescription are extracted by percolation with 70% ethanol, and then concentrated and dried In the process, the volatile components in Moutan cortex are easy to lose, but it is difficult to extract active ingredients such as polysaccharides in Cornus officinalis that have obvious immune-enhancing and anti-aging activities, and Cortex Phellodendron is fried with other medicinal materials, and the alkaline components in Cortex Phellodendri are easily mixed with other medicinal materials. Some acidic components in the medicinal materials react, resulting in the loss of active ingredients. At the same time, the concentrated pills also have the disadvantages of slow dissolution and low bioavailability
[0004] To sum up, although there are many dosage forms of Zhibai Dihuang at present, it can not only fully retain the active ingredients of the prescription Chinese medicinal materials to ensure the curative effect, but also achieve exquisite preparation and small dosage, which can fully reflect the modernization of traditional Chinese medicine preparations. can say no
