Embodiment 1

[0053] The establishment of embodiment 1 fingerprint collection:

[0054]Take 1.0g of the powder of the above-ground part of the blue calyx fragrant tea, accurately weighed, accurately add 25mL of 70% methanol containing 0.2% formic acid, weigh the weight, ultrasonic for 30min, let cool, weigh, make up the lost weight with solvent, shake Evenly, filter, and get the continued filtrate to obtain the test solution;

[0055] (2) HPLC detection:

[0056] Draw above-mentioned step (1) gained need testing solution, inject in the high-performance liquid chromatograph and carry out high-performance liquid chromatography detection, obtain described fingerprint collection;

[0057] Wherein, the chromatographic detection conditions are as follows:

[0058] C18 chromatographic column (250mm×4.6mm, 5μm); methanol (A)-0.1% phosphoric acid (B) gradient elution, the elution program is shown in Table 1, and the running time is 55min; the volume flow rate is 1.0mL / min; the detection wavelength...

Embodiment 2

[0063] The comparison fingerprints of the blue calyx fragrant tea vegetables generated in Example 1 are used as a comparison, and the Chinese medicine chromatographic fingerprint similarity evaluation system software provided by the National Pharmacopoeia is used to measure the similarity of the fingerprints of 12 batches of blue calyx fragrant tea vegetables samples. see results figure 2 and Table 2. A total of 15 common peaks were detected in 12 batches of S. indigo, and six main components including rabdosiin, s. The similarity of 12 batches of blue calyx from different places of origin was between 0.874 and 0.990, with an average of 0.9556.

[0064] Table 2 The results of the similarity determination

[0065]

Embodiment 3

[0066] The investigation of embodiment 3 mobile phase solvent system

[0067] Kromasil 100-5C18 (250×4.6mm, 5μm) chromatographic column was selected. Methanol-0.1% phosphoric acid and acetonitrile-0.1% phosphoric acid were used as the mobile phase to test the influence of different solvent systems on the determination. It was found that the chromatogram of the acetonitrile-0.1% phosphoric acid system showed poor separation of phenolic acids and fewer peaks in the chromatogram. The separation of phenolic acid components in methanol-0.1% phosphoric acid system is better than that in acetonitrile-0.1% phosphoric acid system. Finally, methanol-0.1% phosphoric acid is used as the mobile phase for fingerprint determination, see image 3 .

Abstract

The invention discloses a fingerprint spectrum of herba rabdosiae japonicae as well as an establishment method and application of the fingerprint spectrum. The method comprises preparation of a test sample and high performance liquid chromatography detection conditions, wherein the high performance liquid chromatography detection conditions are as follows: a chromatographic column is a C18 chromatographic column and a mobile phase is a methanol-0.1 percent phosphoric acid solution; a gradient elution manner is adopted: the time is 0min, 30min and 55min, the amount of methanol is 20 percent, 50percent to 100 percent and the sample feeding amount is 3 to 10mu L; the detection wavelength is 232nm, the flow speed is 1.0mL / min and the column temprature is 20 DEG C to 35 DEG C. According to thefingerprint spectrum disclosed by the invention, an established herba rabdosiae japonicae medicinal material fingerprint spectrum determines 15 common peaks, and overall evaluation on medicinal material quality is facilitated and the uniformity and stability of intrinsic quality are ensured through abundant chromatographic peak information and evaluation of the similarity of the common peaks. Thefingerprint spectrum can be used for effectively monitoring the quality of a herba rabdosiae japonicae medicinal material and identifying the authenticity of the herba rabdosiae japonicae medicinal material.

Description

technical field [0001] The invention relates to the technical field of quality control of traditional Chinese medicinal materials, and in particular to a fingerprint of a calyx calyx and its establishment method and application. Background technique [0002] The blue calyx fragrant tea vegetable comes from Rabdosia japonica (Burm.f.) Haravar. glaucocalyx (Maxim.) Hara, which is mainly distributed in northern provinces such as Heilongjiang, Jilin, Liaoning, Shandong, Hebei and Shanxi, and is rich in resources. Its medicinal part is the dry aerial part. The diameter of the original plant stem is 3-8mm, the surface is gray-green to gray-brown, sparsely pubescent, the center of the section is pithed, not hollow. Leaves gray-green to gray-brown, ovate to broadly ovate when flattened, 5-13cm long, 3-7cm wide; margins obtusely serrated, sparsely pilose or pilose on both sides. Harvest in summer and autumn, remove impurities after harvest, and dry in the shade or in the sun. [0...
