Problems solved by technology

[0005] The traditional extraction process of Rhodiola rosea is water extraction and alcohol precipitation. This method cannot fully release the active ingredients, and long-term decoction wastes energy. At the same time, a large amount of invalid substances are also extracted, which brings great impact to the subsequent impurity removal. difficulty

Abstract

The invention relates to a preparation method for traditional Chinese medicine preparation, in particular to an extraction method for rhodiola rosea injection with the assistance of microwave cell disruption. Large rhodiola rosea injection has the effect of promoting blood circulation to remove blood stasis. The preparation method comprises the following steps: the medicine of rhodiola rosea is moistened in a medicine moistening machine until the medicine is moistened fully and the water is exhausted; the medicine is subjected to microwave cell disruption in a tunnel microwave drier with the microwave power being 20kw and the conveyer belt speed being 2m / min; after cell disruption, the medicine is placed in an extraction jar for low-temperature and decompression extraction at the temperature of 75-80 DEG C; and a salidroside extracting solution is obtained. By adopting the technology of extraction with the assistance of microwave cell disruption, the dried medicine is moistened by the medicine moistening machine, so that the dehydrated cells are led to absorb water, expand and absorb microwave energy to the maximum, which is beneficial for cell disruption. The effective ingredients of the medicine are rapidly released at low temperature and negative pressure, so that the extraction time is greatly shortened, the energy consumption is saved and the impurities are obviously decreased.
