The invention discloses a
quality control method of a dampness-resolving
toxin-vanquishing composition. The dampness-resolving
toxin-vanquishing composition is mainly prepared from the following components: herba ephedrae, fried
semen armeniacae amarae,
gypsum, liquorice root, herba pogostemonis, cortex magnoliae
officinalis, rhizoma atractylodis fried with
bran, fried
semen tsaoko, rhizoma pinellinae praeparata, poria cocos, radix et rhizoma rhei, radix astragali,
semen lepidii and radix paeoniae rubra. The
quality control method of the dampness-resolving
toxin-vanquishing composition comprises the following steps: (1) determining the content of total
anthraquinone, the content of free
anthraquinone, the content of
ephedrine hydrochloride, the content of
pseudoephedrine hydrochloride andthe content of
paeoniflorin in the dampness-resolving toxin-vanquishing composition by adopting
high performance liquid chromatography, and calculating the content of combined
anthraquinone, wherein the combined anthraquinone content is equal to the sum of the total anthraquinone content and the free anthraquinone content; and (2) identifying ephedra, liquorice and mangnolia
officinalis by adopting thin-layer
chromatography. By implementing the method, each link in the production process of the dampness-resolving toxin-vanquishing composition can be well controlled, and the quality stability and
controllability of the product are effectively ensured.
