Embodiment 1

[0032] 1. Extraction of total alkaloids from mulberry leaves

[0033] like figure 1 As shown, add ddH according to the material ratio (W / V=1:8) 2 O, heating and refluxing extraction, gauze filtration and suction filtration, repeated three times, combined filtrates, concentrated, dynamic adsorption loading (2BV / h) LSI-010 cation exchange column, 10-15BV ddH 2 After O elution until the effluent becomes neutral, 7-8BV 0.5mol / L ammonia water is eluted, the eluent is collected and concentrated, suction filtration, dynamic adsorption and loading (2BV / h) D941 anion exchange resin, and the unadsorbed part is collected , concentration, activated carbon adsorption, decolorization, concentration, freeze-drying, Rays salt colorimetry to detect the total alkaloid content, the alkaloid content reaches 52%.

[0034] 2. Qualitative and quantitative detection of total alkaloids in mulberry leaves

[0035] Qualitative detection (thin layer chromatography): DNJ was used as a reference substan...

A new choice is provided for preventing and treating cerebral ischemic stroke; specifically, the invention relates to application of mulberry leaf total alkaloids in drugs for preventing and treating cerebral ischemic stroke. The invention relates to application of mulberry leaf total alkaloids in medicines for preventing and treating cerebral ischemic diseases. The invention discloses application of mulberry leaf total alkaloids in preparation of drugs for preventing and treating cerebral hypoxia fatigue. The invention relates to application in preparation of medicines for preventing and treating myocardial ischemia diseases.

Description

technical field [0001] The invention relates to a new use of mulberry leaf extracts, in particular to the application of total alkaloids of mulberry leaves in the preparation of medicines for preventing and treating cerebral ischemia injury. Background technique [0002] Mulberry leaves are the leaves of Morus alba L., a deciduous tree plant of the Moraceae family. It has the functions of dispersing wind-cold, clearing lung and moistening dryness, calming liver and improving eyesight. Although mulberry leaf has a long history of use as a traditional Chinese medicine, there is no report on the efficacy of mulberry leaf and its total alkaloid effective parts in reducing cerebral ischemia injury. Our previous studies have confirmed that total alkaloids are obtained by extracting and purifying mulberry leaves. The overall animal experiments have confirmed that preventive administration of total alkaloids from mulberry leaves can effectively reduce cerebral ischemia injury. SU...
