Embodiment 1

[0064] Example 1. Detection of the fingerprints of Xiasangju sugar-containing granules

[0065] 1. Instruments and reagents

[0066] 1.1 Instruments Waters2695 high performance liquid chromatography, Waters 2996 ultraviolet detector, Empower chromatography workstation, AE-200 electronic analytical balance.

[0067] 1.2 Reagent Chlorogenic acid reference substance; Methanol (chromatographically pure), double distilled water, acetic acid (analytical pure).

[0068] 2. High performance liquid chromatography

[0069] 2.1 Chromatographic conditions: Chromatographic conditions: the chromatographic column is filled with octadecylsilane bonded silica gel (SunfrieC 18 , analytical column 150mm×4.6mm, 5um); the mobile phase is a gradient eluent composed of 1% acetic acid and methanol, column temperature: 30°C; UV detection: wavelength 290nm; flow rate 1.0mL.min -1 ; Analysis time: 65min. Injection volume: 10 μL each of the test solution and the reference solution. The number of the...

Embodiment 2

[0075] Example 2. Detection of fingerprints of 10 batches of Xiasangju sugar-containing granules

[0076] 10 batches of Xiasangju granules were taken, and tested according to the conditions of Example 1, and the HPLC spectra of 10 batches of samples were obtained, as shown in FIG. 2 . Through the comparison of 10 batches of HPLC chromatograms, the similarity evaluation is carried out, and the characteristic common peaks are determined:

[0077] There are 20 common peaks in the fingerprint spectrum. Now the retention time of the spectrum, the average value of the peak area and the total peak area are summarized, as follows:

[0078] For peak No. 1, the average retention time RT is 1.57min, the RSD is 2.06%, the peak area is 1542541, the RSD is 23.75%, accounting for 2.46% of the total peak area.

[0079] For peak No. 2, the average retention time RT is 1.91min, the RSD is 1.08%, the peak area is 1660403, the RSD is 23.47%, accounting for 2.72% of the total peak area.

Embodiment 3

[0106] Example 3 The determination method of fingerprint of Xia Sangju sugar-containing granule

[0107] Reference solution: same as embodiment 1

[0108] (b) Preparation of the test solution: Accurately weigh 2.0 g of Xia Sangju granules and place in a stoppered conical flask, accurately add 20 ml of methanol, stopper tightly, soak for 2 hours, and after ultrasonic treatment for 30 minutes, put it to room temperature and make up the reduced volume with methanol. Shake well, filter, evaporate the filtrate to dryness, dissolve the residue with methanol, put it in a 2mL volumetric flask, and add methanol to the mark. Shake well and filter with a pinhole microporous membrane to obtain the test solution.

[0109] (c) Chromatographic conditions: the chromatographic column is filled with octadecylsilane bonded silica gel (Sunfrie C 18 , analytical column 150mm × 4.6mm, 5um); using gradient elution, the mobile phase is a gradient elution solution (phase B) composed of 1% L sodium a...

Abstract

This invention relate to the found of summer mulberry chrysanthemum preparation finger print, refer methodical control of quality of Chinese traditional medicine preparation. The invention is a method of founding HPLC finger print to detect alcohol extracted thing in summer mulberry chrysanthemum preparation. The method include;(a) preparation of control article solution;(b) preparation of examining solution; (c) chromatographic condition; chromatographic column take octadecyl silane bonded silica gel as padding;adopt gradient elution, mobile phase is gradient elution liquid composed by 0.1 to 3 percent acetic acid and methanol; column temperature;25 to 50 deg; ultraviolet detecting wavelength is 285 to 295 nm;velocity of flow;0.5 to 1.5 ml per min; time;30 to 80 min;(d) measuring; high efficiency liquid chromatography to gain finger print. This invention can validly characterize quality of summer mulberry chrysanthemum preparation, in favor of monitoring product quality; possess merit of method handiness, stable, high degree of precision, good reappearance; the invention can quickly and exactly discriminate the product.

Description

technical field [0001] The invention relates to a quality control method of traditional Chinese medicine preparations, in particular to a method for constructing high-performance liquid chromatography fingerprints and standard fingerprints of Xiasangju preparations. Background technique [0002] Xiasangju preparation is made from traditional Chinese medicinal materials Prunella vulgaris, mulberry leaves, and wild chrysanthemums, which are extracted with water and made according to conventional pharmaceutical processes. Wind-heat cold, conjunctival congestion and headache, high blood pressure, dizziness and tinnitus, sore throat, treatment of sores and swollen toxins. Xiasangju preparations are listed in the fifteenth volume of Chinese medicine prescription preparations of the Ministry of Health of the People's Republic of China. Xiasangju granules are very popular traditional Chinese medicine preparations. Now there are Xiasangju sugar-free granules, X...
