Embodiment Construction

[0013] The water extraction process of Shaqing Runke Granules includes the following steps.

[0014] (1) Accurately weigh the baicalin reference substance dried to constant weight, add methanol to dilute and constant volume, and prepare a reference substance solution containing 0.2167mg baicalin per 1ml.

[0015] (2) Scutellaria baicalensis and other medicinal materials are reflux extracted according to the orthogonal table, the extracts are filtered and combined, and the volume is set to a certain volume, and 5ml of each extract is accurately pipetted, evaporated in a water bath, dissolved in methanol and adjusted to a 25ml volumetric flask. Shake the sample well, filter it with a microporous membrane filter (0.45 μm), and take the subsequent filtrate to obtain the test sample.

[0016] (3) Prepare the negative control solution of Scutellaria baicalensis according to the proportion of the prescription, and the treatment method of the control solution is the same as that under...

Abstract

The invention belongs to the technical field of drug, and particularly relates to a Shaqing Runke granule water-extraction process which is convenient for preparation and high in efficiency. The Shaqing Runke granule water-extraction process includes following steps: (1), precisely weighing a baicalin reference sample dried to constant weight, adding methanol for diluting, and fixing volume to obtain a reference sample solution containing 0.2167mg of baicalin in each 1ml; (2), performing reflux extraction on medicinal materials such as Scutellaria baicalensis according to an orthogonal table, merging extraction solutions after being filtered, fixing volume to a certain value, precisely weighing 5ml of each extraction solution, volatilizing through water bath, adding methanol for dissolving, and fixing volume in a 25ml volumetric flask; (3), preparing a Scutellaria baicalensis negative reference solution according to a prescription proportion, wherein a method for treating the reference solution is identical with an Item for preparing a test solution; (4), respectively sucking and injecting 10 ug of the reference sample solution, the negative reference solution and the test solution into a liquid chromatograph, wherein the negative reference solution is free of interference at 280nm.

Description

technical field [0001] The invention belongs to the technical field of medicines, and in particular relates to a water extraction process of Shaqing Runke Granules. Background technique [0002] Shaqing Runke Granule is a compound preparation of traditional Chinese medicine, which is composed of Nansha ginseng, scutellaria baicalensis, ephedra and other traditional Chinese medicines. It has the effects of promoting body fluid and moistening dryness, relieving cough and reducing phlegm. The medicinal part of Scutellaria baicalensis is the root, which is cold in nature and bitter in taste. It has the effects of clearing away heat and dampness, purging fire and detoxifying, cooling blood and stopping bleeding. In recent years, with the in-depth research on its active ingredients baicalin and baicalein, it has been found that the extract of Scutellaria baicalensis root, especially flavonoids, has antibacterial, antiviral, antitumor, antipyretic, analgesic, and antioxidant effect...
