Technique for preparing fugui ostealgia compound by microorganism fermentation method

The invention relates to a technique for preparing a fugui ostealgia compound by a microorganism fermentation method, comprising the following steps: all medicinal material are weighed according to the proportion of the fugui ostealgia compound, sterilized after being soaked by distilled water, inoculated with aspergillus niger and continuously cultured, the fermented medicinal materials are heated, circulated, extracted and filtered to obtain an extracting solution, and the extracting solution is centrifuged, concentrated and kept constant volume. The fugui ostealgia compound prepared according to the technique improves the curative effect of the medicine, lowers the toxic or side effect of the medicine, has low cost and is suitable for large-scale production.
