The invention belongs to the technical field of the research and development of
medicine products, and relates to a method for preparing a compound
ginseng preparation and the antioxidation activity of the compound
ginseng preparation. The method comprises the following steps of: adding 70 percent
ethanol into
ginseng and szechuan tangshen root, leaching at
room temperature, performing
ultrasound at the temperature of 30 DEG C under the condition of power of 80 W for 30 minutes, filtering, extracting filter residues once again by using 70 percent
ethanol in an amount 6 times and 4 times that of the filter residues respectively, and filtering to obtain filtrate; mixing the filtrate, and recovering the
ethanol to obtain a ginseng and szechuan tangshen root extract; centrifuging
porphyridium cruentum by using a centrifugal
machine of which the rotation speed is 5,000 revolutions / minute for 10 minutes, suspending in
phosphate buffer of which the concentration is 50 mmol / L and the pH value is 7.4, performing ultrasonication, centrifuging by using a high-speed freezing centrifugal
machine to obtain supernate, and freezing and
drying to obtain a dry substance; and mixing the dry substance and the ginseng and szechuan tangshen root extract uniformly to obtain the compound
ginseng preparation. The compound
ginseng preparation has an antioxidation effect.
