Organic Lycium barbarum powder is a modern preparation form, and the stability control of its active ingredients is the core challenge of pharmaceutical intermediates suppliers ' application. Organic Lycium barbarum powder is rich in heat-sensitive and light-sensitive components such as Lycium barbarum polysaccharide, betaine, and carotenoid, which are easily degraded during processing and storage. 
Pretreatment of raw materials is the first line of defense to ensure the quality of organic medlar powder. Organically certified fresh Lycium barbarum fruit in authentic producing areas (such as Zhongning, Ningxia) should enter the quick-freezing process at -40℃ within 8 hours after harvesting to effectively lock the active substances. In the pharmaceutical intermediate suppliers' thawing process, gradient heating technology is used to avoid the loss of juice caused by ice crystals piercing the cell structure. During the cleaning process, ozone water is used to remove pesticide residues, and at the same time, the waxy layer on the epidermis of organic Lycium barbarum powder is preserved to the maximum extent, which is a natural antioxidant barrier.
Low-temperature grinding and drying constitute the key technical nodes. The pharmaceutical intermediate suppliers' production of organic Lycium barbarum powder generally adopts a freeze-drying and grinding combined process: the material is dehydrated to a water content of 15% in a vacuum environment at -35℃, and then micronized in a low-temperature crushing bin (≤-25℃) protected by nitrogen. Under this process, the retention rate of Lycium barbarum polysaccharide in organic Lycium barbarum powder can reach more than 92% of fresh Lycium barbarum, which is much higher than the traditional hot air drying level of 65%. The whole process of light-avoiding operation and inert gas protection effectively prevented the photooxidative degradation of carotenoids.
Multi-dimensional scheme is needed to strengthen the stability of pharmaceutical intermediate suppliers' preparation. Given the easy moisture absorption and caking of organic Lycium barbarum powder, a protective layer was formed with sodium alginate-chitosan composite wall material by microencapsulation embedding technology, so that the product remained fluid in the humidity of 70%. The construction of the antioxidant system is particularly critical: adding natural tocopherol (0.05%-0.1%) and rosemary extract synergistically can control the peroxide value of organic Lycium barbarum powder below 5meq/kg and extend the shelf life to 24 months.
The pharmaceutical intermediate suppliers' quality control system focuses on monitoring key indicators. In addition to routine microbial detection, three core quality control points should be established for organic Lycium barbarum powder: ① determination of Lycium barbarum polysaccharide content (≥ 4.0%) by phenol-sulfuric acid method; ② Determination of betaine retention rate (≥ 85%) by HPLC-ELSD; ③ The degree of carotenoid degradation (△E≤3.0) was monitored by color difference meter. The accelerated test showed that (40℃/75%RH), the retention rate of active ingredients of organic Lycium barbarum powder with optimized technology was still more than 90% after 6 months.
Innovative preparation technology is expanding the application boundary. Nano-emulsification technology successfully applied organic Lycium barbarum powder to ophthalmic gel, and its bioavailability increased by 3.2 times. Solid dispersion technology solves the problem of thermal decomposition in tablet production. With the breakthrough of sustained-release coating technology, the application prospect of organic Lycium barbarum powder in gastrointestinal targeted drug delivery systems is broad, which provides a new direction for the development of adjuvant drugs for diabetes.
The continuous research on organic Lycium barbarum powder in pharmaceutical intermediate suppliers is promoting its transformation from raw materials to tohigh-value-addedd preparations. Through interdisciplinary technological innovation, the problem of stabilizing active ingredients has been continuously overcome, and this traditional medicinal material has been rejuvenated in the modern medical system. How to keep the stability of active ingredients in the pharmaceutical intermediate suppliers' production of organic Lycium barbarum powder?

Organic Lycium barbarum powder is rich in heat-sensitive and light-sensitive components such as Lycium barbarum polysaccharide, betaine, and carotenoid, which are easily degraded during processing and storage. Pharmaceutical enterprises need to ensure the constant quality of organic Lycium barbarum powder from raw materials to finished products through systematic process control.
