Obtained a patent for the method of ultrasonically preparing nanometer natural medicine particles

The Key Laboratory of Northwestern Characteristic Plant Resources Chemistry of the Chinese Academy of Sciences, Lanzhou Institute of Chemical Physics, Chinese Academy of Sciences (Gansu Provincial Key Laboratory of Natural Medicine), has developed a method for preparing nano-scale natural medicinal particles using liquid phase ultrasound technology. It was learned on July 16 that the method was granted a national invention patent authorization (method for preparing nanometer natural medicinal particles by liquid phase ultrasound, patent number ZL200910117753.X).

The invention uses natural medicinal materials as raw materials, and produces nano-sized particles through primary crushing, liquid phase ultrasonic crushing and vacuum drying techniques. The advantage of the invention is that it can fully crush the natural Chinese medicinal materials, make the particle diameter of the natural medicinal materials reach the nano-level, and ensure that the main characteristics of the nano-scale natural medicinal particles and the original medicinal materials are basically consistent. This method not only guarantees the original medicinal properties of the natural medicinal materials, but also makes the natural medicinal materials have the nanometer scale, so that the medicinal effects can be better exerted, and the production process is simple and easy to scale production.

Nanomaterials refer to materials with a scale of nanometers, which have a high degree of dispersibility and a large specific surface, so that they have unique physical and chemical properties. Under the premise of conforming to the traditional Chinese medicine theory, the use of liquid phase ultrasonic technology to crush Chinese herbal medicine into medicinal materials particles that maintain the original natural medicinal properties and have nano-scale scales is the key technology for the modernization of traditional Chinese medicine.
