Semen Astragali Complanati Quality Standards Studies

Semen astragali complanati, the dried seed of Astragalus complanatus R.Br.. The tradition thought this has warming and invigorating the liver and the kidney, controlling emission, reducing urine,improvingacuity of vision effect. Modern pharmacological research shows semen astragali complanati extract has improved blood rheology index, lower blood pressure, regulation of blood lipids, inhibit platelet aggregation, protect the liver, enhance immune function, anti-inflammatory, analgesic and regulating role of the central nervous system. Semen astragali complanati contained chemical composition mainly of amino acids, flavonoids, fatty acids, trace elements and so on. Shaanxi Dali tradition of the origin of the center produced semen astragali complanati called Tongjili ,and is genuine crude drugs. Be accompanying the step that traditional Chinese medicine modernizes, Chinese medicinal crop normalizing is regarded highly by people , Chinese medicinal crop quality level also progress and improves and perfects ceaselessly. But base of 2005 printing plate currently in effect pharmacopoeias middle quality level difficult to be used as medicine face to face source chaos semen astragali complanati carries out the mass under the control of. For perfect semen astragali complanati medicinal material quality standards,the following the problem has been carried out studies:1.Study of Chinese materia medica studies: By looking up the document the ancient times , systematic Chinese materia medica textual criticism,have expounded typical that semen astragali complanati distributes with medicine compatibility , place of production at all time; Have summed up semen astragali complanati's as well as the nature effect , incompatibility of drugs in a prescription concocting method at all time.2.Resource learns to study: Look up, and collect on the spot investigation by the specimen and the relevance document, the summary puts up semen astragali complanati scattering , host place of production produces condition , the plant organism's habits characteristic and medical resource uses condition and the condition applying other.3.Traditional Chinese medicine study of appraisal studies: Theuse Chinese native medicine appraisal method, and its was common to semen astragali complanati false has carried on the base original, the character, microand the physics and chemistry distinction.4.Semen astragali complanati DNA molecule mark studies: Used the PCR technology toestablish the semen astragali complanati RAPD response to expand increases thesystem, and used in to distinguish its three kind of common false.5.Semen astragali complanati infrared spectrum research: Uses Fourier to transform theinfrared spectrum the unidimensional infrared light spectrogram todistinguish semen astragali complanati and its false, finally demonstrated can obviouslyrelate the farther variety difference with the blood relationship.6.Semen astragali complanati mass detecting project studies: Through the different sources of water samples, ash, extract and flavonoids Determination, norms semen astragali complanati medicine quality control indicators, drawn it water should not exceed 12% ash content of not more than 4%, acid insoluble ash content is not more than 1.5%. Heat soaks law determining water-solubility extract contents not being lower than 21%.50% alcohol fever soaks law determining alcohol extract not being lower than 17%. Always yellow ketone of semen astragali complanati contents can't count with rutin lower than 0.9%.
