Plantain-herb freshly-squeezed freeze-dried powder decoction piece and preparing technology thereof

Abstract

The invention discloses a plantain-herb freshly-squeezed freeze-dried powder decoction piece and a preparing technology thereof. The preparing technology includes the steps that a plantain-herb medicinal material is harvested to be cleanly selected, leached and squeezed while the plantain-herb medicinal material is fresh, and medicinal juice is filtered; the medicinal dregs are stirred by adding water, filtered and squeezed; the obtained medicinal juice is combined to be subjected to pressure reducing concentration and freeze drying, and the freeze-dried product is collected and smashed to be subjected to vacuum package. By means of the plantain-herb powder decoction piece prepared with the method, polar effective constituents and non-polar effective constituents in the medicinal material are furthest and simultaneously reserved; the decoction piece is beneficial to storage and transport, convenient to regulate, controllable in quality and reliable in curative effect and is of great significance in guaranteeing the traditional-Chinese-medicine clinical effect. The method is applied and popularized, and the remarkable social meanings and remarkable economic benefits are achieved.

AI Technical Summary

Problems solved by technology

The preparation process of granular decoction pieces, the extraction is not only time-consuming and energy-consuming, but also because a large amount of water is often used as a solvent, it is difficult to extract the non-polar active ingredients in the medicinal materials

In addition, since the plantain medicinal materials used for extraction are also dried and stored for a long time, the loss of active ingredients is also great
