Embodiment 1

[0025] 1) Preparation of reference substance solution: Take an appropriate amount of gallic acid reference substance, add methanol to make a solution containing 1mg per 1mL, and obtain it.

[0026] 2) Preparation of the test solution: Take 1.0 g of the powder of this product, add 50 mL of 10% methanol solution by volume, sonicate for 60 minutes, filter, evaporate the filtrate to dryness, add 1 mL of methanol to dissolve the residue, and obtain.

[0027] 3) Spotting, unfolding, and inspection: draw 5 μL of each of the above two solutions, and spot on the same silica gel GF 254 On a thin-layer board, use cyclohexane-ethyl acetate-formic acid with a volume ratio of 8:6:1 as the developer, develop, take out, dry in the air, and inspect under ultraviolet light with a wavelength of 254nm.

[0028] 4) Result: if figure 1 As shown, different batches of red-backed mothers show spots of the same color at the positions corresponding to the chromatogram of the reference substance. The s...

Abstract

The invention discloses a quality control method of Zhuang medicinal materials roots or leaves of redback christmashush. The method comprises the following steps: firstly, by taking gallic acid in the roots or leaves of redback christmashush as an index component,identifying the gallic acid in the roots or leaves of redback christmashush by adopting a thin layer chromatography, and determining the content of the gallic acid in the roots or leaves of redback christmashush by adopting a high performance liquid chromatography. The quality control method is simple and convenient to operate, has controllable conditions, strong specificity and good stability and repeatability, and can be used for effectively controlling the quality of the Zhuang medicinal materials roots or leaves of redback christmashush. The method has very great practicability.

Description

technical field [0001] The invention belongs to the field of quality control of medical materials, and in particular relates to a quality control method of red-backed Niang, a strong medicinal material. Background technique [0002] Hongbeiniang is a characteristic Zhuang medicine in Guangxi, and it is called "Godag" in Zhuang language. It is the dried whole plant of Alchorneatrewioides (Benth.) Mull.Arg. Also known as red back leaf, red Luo skirt, red hat top and so on. Red-backed Niang is quite rich in resources in Guangxi and has a long history of medicinal use. It has the effects of clearing away heat and promoting dampness, dissipating blood stasis, stopping bleeding, killing insects and relieving itching, mainly treating prostatitis, dysentery, dysuria, hematuria, urinary stones or inflammation, redness, leucorrhea, lumbago and leg pain, bruises and swelling; external use to treat traumatic bleeding , urticaria, eczema, etc. Guangxi Zhuang people often use it to tre...
