Abstract
The invention belongs to the technical field of research and development of medical products, and relates to a preparation method for a compound salvia miltiorrhiza preparation and antioxidant activity thereof. The method comprises the following steps of: adding salvia miltiorrhiza and epimedium herb into 70 percent ethanol to lixiviate at room temperature; performing ultrasonic processing for 30 minutes at the temperature of 30 DEG C and at the power of 80 W; filtering; repeatedly extracting filter residue by using 70 percent ethanol in an amount which is 6 times the amount of the filter residue and in an amount which is 4 times the amount of the filter residue respectively; filtering; combining filtrates; recovering the ethanol to obtain salvia miltiorrhiza and epimedium herb extract; centrifuging porphyridium cruentum by using a centrifuge of 5,000r / min for 10 minutes; suspending in 50mmol / L phosphoric acid buffer solution with pH of 7.4; performing ultrasonic crushing; centrifuging by using a high-speed freezing centrifuge to obtain supernatant; freeze-drying to obtain a dry product; and uniformly mixing the dry product with the salvia miltiorrhiza and epimedium herb extract to obtain the compound salvia miltiorrhiza preparation. The product has an antioxidant effect.
Description
technical field [0001] The invention belongs to the technical field of research and development of pharmaceutical products. The invention relates to a preparation method of a compound salvia miltiorrhiza preparation and its antioxidant activity. Background technique [0002] Salvia miltiorrhiza is the dry root and rhizome of Salvia miltiorrhiza Bge. Bitter, slightly cold. GUIXIN, Liver Channel. Promoting blood circulation and regulating menstruation, dispelling blood stasis and relieving pain, cooling blood and eliminating carbuncle, clearing away heart-fire and restlessness, nourishing blood and calming the nerves. Indications for irregular menstruation, amenorrhea and dysmenorrhea, accumulation of lumps in the abdomen, tingling pain in the chest and abdomen, heat pain, sore swelling and pain, restlessness and insomnia; hepatosplenomegaly, angina pectoris. The root mainly contains fat-soluble diterpenoids and water-soluble phenolic acids, as well as flavonoids, triterpe...
