Embodiment 1

[0024] The establishment method of embodiment 1 Taohe Chengqi Decoction substance benchmark

[0025] 1.1 Preparation of Taohe Chengqi Decoction

[0026] Weigh peach kernel, rhubarb, cassia twig, roasted licorice, and Glauber's salt as raw materials according to the original prescription, add 1400ml of water to boil the first four herbs to 500ml, filter, collect the filtrate, add Glauber's salt, slightly boil, put on fire, and get Peach Kernel Chengqi Soup Traditional decoction. Concentrate the traditional decoction of Taohe Chengqi Decoction to 50ml to obtain the concentrated solution of Taohe Chengqi Decoction, which is set aside.

[0027] 1.2 Determination of paste yield

[0028] Take the concentrated solution of Taohe Chengqi Decoction, evaporate to dryness in a water bath at 80°C, pre-freeze in a refrigerator at -25°C for 6 hours, and freeze-dry in a vacuum freeze dryer until the sample is in a loose and anhydrous state. Weigh it and the paste yield is 17.47%. .

Abstract

The invention relates to a method for establishing the substance standard of a taohe chengqi decoction, and belongs to the technical field of Chinese pharmaceutical manufacturing. The method comprisesthe following steps: an extraction process is established, through high-performance liquid chromatography, effective component chromatography is determined, the content is measured, the paste rate ismeasured, and a fingerprint spectrum is established. Firstly, the traditional taohe chengqi decoction is prepared based on a traditional preparation process, the paste rate is measured and determined, a fingerprint spectrum common model is established by adopting the high-performance liquid chromatography, the chromatographic peak is identified through a reference substance, on the basis, the content of amygdalin, rhein, rheum emodin, chrysophanol, physcion, aloe-emodin, cinnamaldehyde and glycyrrhizic acid is measured, and the method can be used for quality inspection of the taohe chengqi decoction.

Description

technical field [0001] The invention belongs to the technical field of traditional Chinese medicine pharmacy, and in particular relates to a method for establishing a substance standard of Taohe Chengqi Decoction. Background technique [0002] Taohe Chengqi Decoction is composed of rhubarb, peach kernel, roasted licorice, cinnamon twig, and mirabilite. , the person is like a madman, the blood comes from the bottom, and the bottom is healed.
