Abstract

The invention relates to the technical field of active substance extraction, in particular to a preparation method of lamiophlomis rotata extracts and the prepared extracts thereof. According to the preparation method of the lamiophlomis rotata extracts, the medicinal herb of the lamiophlomis rotate is extracted with water and an orthogonal test method is utilized to find suitable extraction parameters. The extraction and conversion rate of effective components can be improved, and the quality of extracts is also improved. Experiments show that the extraction effects are best when 30 times ofwater is used to extract the lamiophlomis rotata three times (6: 5: 4) without being powdered for one hour each time at the temperature of 100 DEG C.

Description

technical field [0001] The invention relates to the technical field of extracting active substances, in particular to a method for preparing a unique extract and the prepared extract. Background technique [0002] Lamiophlomis rotata (Lamiophlomis rotata), alias: Daba, Dabuba, is the only species of Lamiophlomis rotata, an important medicinal plant unique to the Qinghai-Tibet Plateau. It has the effects of promoting blood circulation, removing blood stasis, reducing swelling and relieving pain. Folks use the whole herb as medicine, which can treat bruises, muscle and bone pain, stagnation of Qi and waist flashing, yellow water after edema, yellow water in joints, and inflammation of spongy bone. In addition, according to the hemostasis test on rat femoral artery, brachial artery, and carotid artery, it is believed that solitary blindly has a better hemostatic effect. [0003] The Duyiwei dripping pills involved in this patent have functions and indications: promoting blood ...
