The invention provides a determination method of fingerprint of Poecilobdella manillensis. Poecilobdella manillensis, commonly known as yellow-stripped leech, belongs to Arhynchobdellida, Hirudinidae and Poecilobdella, has evident activities on anticoagulation, antithrombosis, thrombolysis and platelet aggregation resistance, and has evident medicinal value. Up to now, no pharmacopeia or local standard records Poecilobdella manillensis, and no reports on fingerprint of Poecilobdella manillensis are present. Poecilobdella manillensis material is determined by efficient capillary electrophoresis, a fingerprint of the Poecilobdella manillensis material is established, and a method of overall quality estimation on the Poecilobdella manillensis material is provided and is used to control the quality of the Poecilobdella manillensis material.
Description
technical field [0001] The invention relates to a method for determining the fingerprint of Hirudo phenanthae medicinal material, which belongs to the technical field of drug analysis. Background technique [0002] The Philippine leech (Poecilobdella manillensis), commonly known as the Phnom Penh leech, belongs to the genus Hirudidae, Hirudidae, and the genus Hirudo. Significant anticoagulant, antithrombotic, thrombolytic, and antiplatelet aggregation activities, the main chemical components are fatty acids, amino acids and proteins, of which the active components have been reported as hirudin P6, hirudin P18, hirudin A and phenanthrene Hirudin B, the acute toxicity test shows that Hirudinus phenatus has no obvious toxic and side effects, so it has significant medicinal value. So far, it has not been recorded in the Pharmacopoeia and local standards, and there is no report about the fingerprint of Hirudinium phenatus. Contents of the invention [0003] The purpose of the ...
