Extraction technology of Lemai particle crude medicines

The invention provides an extraction technology of Lemai particle crude medicines. The extraction technology comprises the following operation steps: (1) weighing crude medicines by weight proportioning on prescription: 8 parts of radix salviae miltiorrhizae, 4 parts of ligusticum wallichii, 4 parts of radix paeoniae rubra, 4 parts of safflower carthamus, 2 parts of radix aucklandiae, 2 parts of cyperus rotundus and 1 part of hawthorn fruits; and (2) adding the crude medicines weighed in step (1) in an extraction solvent, extracting by decompression, and finally collecting extract. The invention also provides the extract prepared by the technology as well as the applications of the extract. According to the extraction method, the yield of the extract is increased remarkably, the medicine effect activity of the extract is enhanced, the utilization rate of the crude medicines is improved, the material cost is reduced and the extraction technology is applicable to industrial production.
