Abstract

The invention discloses a vertigo treatment drug compound Yuntong and its preparation process and quality control method. The bulk drugs include: scutellaria, radix bupleuri, Rhizoma Pinellinae Praeparata, Codonopsis pilosula, liquorice, tangerine peel, rhizoma alismatis, bighead atractylodes rhizome, poria, Gastrodia elata, chrysanthemum, Uncaria tomentosa, acorus gramineus, panax notoginseng, leech, and radix puerariae. The preparation method comprises: conducting ethanol reflux extraction on the bulk drugs; concentrating the extracted solution, carrying out drying, crushing and sieving, adding soluble starch and microcrystalline cellulose, mixing the materials evenly, performing granulating and capsule filling, thus obtaining the compound Yuntong capsule. The invention also relates to establishment of a standard fingerprint spectrum, establishment of a test sample fingerprint spectrum and comparison of the two spectrums. The fingerprint spectrum of the drug shows 17 main chromatographic peaks at the place of 283nm, and the chemical structure of one chromatographic peak therein can be determined as baicalin, and baicalin can be chosen as an index component to perform content determination. The method has the advantages of good precision, stability and reproducibility, can be used for quality control of the drug and preparations provided by the invention, and provides reference for clinical application choice.

Description

Technical field [0001] The invention relates to a capsule for treating vertigo, in particular to a medicament for treating vertigo, a preparation method and a quality control method thereof. Background technique [0002] Dizziness is a common clinical syndrome, which is more common in middle-aged and elderly people, but also in young people.
