Abstract
The invention discloses a radix bupleuri extract. The radix bupleuri extract is obtained by extracting radix bupleuri with a Na2CO3 aqueous solution. Every 1 g of the extract is equivalent to 5-6 g of the raw medicinal material. The invention further discloses a preparation method of radix bupleuri granules. In a finished product prepared by the preparation method of the radix bupleuri granules, saikosaponin a and saikosaponin d are almost not decomposed, such that a curative effect of the medicine is also improved.
