Problems solved by technology

At this stage, the traditional simple methods such as seeing, tasting, sniffing, and touching have been very limited in the identification of Chinese herbal medicines, and there are a large number of false positives and false negatives in chromatographic methods such as HPLC, IR, NIR, and TLC, which can easily lead to bias in conclusion

Embodiment 1

[0031] Example 1 Construction of characteristic maps of Eucommia ulmoides and Eucommia ulmoides

[0032] 1. Main instruments and reagents

[0033] Ultra-high performance liquid chromatography; ACQUITY UPLC HSST3 chromatographic column (2.1 mm×100mm, 1.7 μm); AY120 tray electronic analytical balance (Shimadzu, Japan); methanol is chromatographically pure (Opsen brand); liquid phase water is Watsons Distilled water; other reagents were of analytical grade; the original medicinal materials of Eucommia were purchased from medicinal materials market.

[0034] 2. Experimental method

[0035] 2.1 Preparation of eucommia medicinal material and salt eucommia medicinal material:

[0036] Preparation of Eucommia medicinal material: take the original medicinal material of Eucommia ulmoides, scrape off the residual rough skin, wash away impurities such as sediment with water, dry or wipe slightly with a dry cloth, cut into 2.5mm filaments with a guillotine, graded by size, at 50 Dry it ...

Embodiment 2

[0099] Example 2 The method of identifying the Eucommia medicinal material by using the standard characteristic map

[0100] Randomly buy a batch of Eucommia medicinal materials from the market to identify its authenticity.

[0101] First, according to the establishment method of the characteristic map described in embodiment 1, set up the characteristic map of the eucommia medicinal material to be detected; then compare with the standard characteristic map of the eucommia medicinal material and the salt eucommia medicinal material established by the method of embodiment 1; According to the characteristic map similarity evaluation software promulgated by the bureau, the characteristic map of this batch of medicinal materials is consistent with the standard characteristic map of Eucommia medicinal material, so it can be determined that this batch of medicinal materials is Eucommia medicinal material.

Abstract

The invention relates to the technical field of detection of Chinese medicinal materials, in particular to a method for constructing specific chromatograms of cortex eucommiae and fried cortex eucommiae and a method for identifying specific chromatograms of cortex eucommiae and fried cortex eucommiae. The method for constructing the specific chromatograms comprises the following steps: S1, precisely weighing cortex eucommiae medicinal materials and fried cortex eucommiae medicinal materials to prepare a cortex eucommiae sample solution and a fried cortex eucommiae sample solution; and S2, analyzing the cortex eucommiae sample solution and the fried cortex eucommiae sample solution by an ultra-high performance liquid chromatography to obtain a cortex eucommiae specific chromatogram and a fried cortex eucommiae specific chromatogram. The specific chromatograms can reflect the characteristic peak information of the sample more comprehensively, and identify the characteristic difference between cortex eucommiae and fried cortex eucommiae from the molecular level, and the method has good precision, stability and reproducibility; and the cortex eucommiae medicinal materials and the friedcortex eucommiae medicinal materials can be authenticated or identified according to the characteristic spectrums.

Description

technical field [0001] The invention relates to the technical field of detection of traditional Chinese medicinal materials, in particular to a method for constructing and identifying characteristic maps of Eucommia ulmoides and Eucommia salt medicinal materials. Background technique [0002] Eucommia is the dry bark of Eucommia ulmoides Oliv. "Shen Nong's Materia Medica" stated: "Eucommia, also known as Sixian, Mumian, Sizhong, Yusipi, etc., treats low back pain, nourishes the middle and replenishes essence, strengthens muscles and bones, strengthens will, eliminates itching and dampness in the yin, and relieves urination. "Yu Li"; "Bielu of Famous Doctors" records: "Eucommia is warm in nature and sweet in taste, nourishes the liver and kidney, and strengthens bones and muscles"; The previous editions of "Chinese Pharmacopoeia" all recorded Eucommia bark as a medicinal material, and its nature and flavor are sweet and warm. Return liver, kidney channel. It is used for li...
