Abstract

The invention provides a detection method of the content of wild baicalin in a traditional Chinese medicine, and belongs to the field of traditional Chinese medicines. The detection method comprises astep of preprocessing a sample and a step of injecting and detecting the sample, wherein the sample is herba erigerontis preferably; ethanol is adopted for extraction in preprocessing of the sample;the sample is injected in the conditions as follows: a C18-bonded packed column is adopted, a mobile phase comprises acetonitrile, tetrahydrofuran and 0.1%-0.2% phosphoric acid at a ratio of 7:14:79,the flow rate is 1.0 ml / min, and the column temperature is 40 DEG C. The detection method has the advantages of being stronger in adaptability, reducing the preprocessing step of the sample and more accurately reflecting the content of the wild baicalin in the traditional Chinese medicine.

Description

technical field

[0001] The invention belongs to the technical field of quality control of Chinese medicinal materials, and in particular relates to a detection method of scutellarin in Chinese medicinal materials. Background technique

[0002] Erigeron breviscapus (Erigeron breviscapus) is the dry whole plant of Erigeron breviscapus (Vant.) Hand-Mazz, a plant of the genus Asteraceae. The power of removing blood stasis, dredging collaterals and relieving pain is used for cold headache, rheumatism pain, paralysis caused by cerebrovascular accident, etc. ("National Chinese Herbal Medicine Compilation").

[0003] Scutellarin (breviscapus B) is an active ingredient of flavonoids isolated from Erigeron breviscapus (Vant.) Hand-Mazz. , breviscapine dripping pills, etc. Therefore, the content of scutellarin in breviscapine medicinal materials has become the symbolic component of Chinese medicinal materials used to determine the registration of breviscapine herb.
