The invention belongs to the technical field of
processing of health-care food, and relates to a compound Siberian solomonseal
rhizome preparation capable of improving the vigor of
superoxide dismutase. A method for preparing the compound Siberian solomonseal
rhizome preparation comprises the following steps of: adding 70 percent
ethanol in an amount which is 10 times that of 12 grams of Siberian solomonseal
rhizome and 9 grams of largehead atractylodes rhizome, leaching at
room temperature for 10 hours, performing hermetic
ultrasound for 30 minutes, filtering, extracting filter residues once again from 70 percent
ethanol in an amount which is 6 times and 4 times that of the filter residues respectively; mixing the filtrate, and recovering the
ethanol to obtain a Siberian solomonseal rhizome extract and a largehead atractylodes rhizome extract; centrifuging 20 grams of
porphyridium cruentum for 10 minutes by using a centrifugal
machine, suspending in 50 mmol / L of
phosphate buffer, of which the pH value is 7.4, performing ultrasonication, centrifuging for 15 minutes 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 with the Siberian solomonseal rhizome extract and the largehead atractylodes rhizome extract uniformly to obtain the compound Siberian solomonseal rhizome preparation. The compound Siberian solomonseal rhizome preparation can be used for developing new natural antioxidants in fields of food, medicines and the like and is favorable for industrial production.
