Abstract

The invention provides a method for establishing fingerprints of schisandra chinensis medicinal materials and erigeron breviscapus pulse-activating capsules. The method is divided into schisandra chinensis test sample treatment, erigeron breviscapus pulse-activating test sample treatment and reference substance solution preparation, and separate liquid phase detection; the liquid phase conditionsare as follows: acetonitrile is taken as a mobile phase A, water is taken as a mobile phase B, and gradient elution is carried out for 0-50 minutes: 35%-85% A, 65%-15% B; the column temperature is 30-40 DEG C, the detection wavelength is 240-260 nm, and the flow rate is 0.6-1.5 ml/min; according to the invention, the correlation between the schisandra chinensis medicinal material and the erigeronbreviscapus pulse-activating capsule is obtained through fingerprint comparison, and the quality control and tracing of the product are facilitated.

Description

technical field [0001] The invention belongs to the field of detection of traditional Chinese medicinal materials and preparations, in particular to a method for establishing fingerprints of lignans in Schisandra chinensis medicinal material and Dengzhan Shengmai Capsules Background technique [0002] Schisandra chinensis is the dry and mature fruit of Schisandra chinensis (Turcz.) Baill., a plant of Magnoliaceae, commonly known as "Northern Schisandra". There are astringent and astringent, nourishing qi and promoting body fluid, invigorating the kidney and calming the heart. Used for chronic cough and shortness of breath, nocturnal spermatorrhea, enuresis, frequent urination, chronic diarrhea, spontaneous sweating, thirsty wounds, internal heat and thirst, palpitations and insomnia. Schisandra lignans are lignans with 1,2,3,4-biphenyl-1,3-cyclooctadiene as the core, which is the main pharmacological active ingredient in Schisandra chinensis. There are more than 150 kinds ...
