Embodiment 1

[0037] Example 1 The establishment of the X-ray powder diffraction Fourier fingerprint of Yu Yuliang

[0038] 1) X-ray powder diffraction experimental conditions Cu kα1 radiation, graphite monochromator, tube pressure 40kV, tube current 100mA. The 2θ scanning range is 3°~70°, and the scanning speed is 10° / min. Slit width: DS=SS=1°, RS=0.15mm. The step size is 0.02°.

[0039] 2) Preparation of the test product Take Yu Yu grain medicinal materials, crush them, and pass through a 200-mesh sieve to obtain the test product for XRD analysis. The test product was measured on the machine according to the set instrument conditions.

[0040] 3) Phase analysis Use Mid Jade5 to first conduct phase analysis on the X-ray diffraction pattern of Yu Yuliang, and match the obtained diffraction data with the International Powder Diffraction Data Center·JCPDS standard card. The phase analysis diagrams of some representative samples are given below, see Figure 1~6 .

Abstract

Aiming at the defects of a conventional limonite mass control techniques, the invention provides a method for establishing an XRDFourier standard fingerprint spectrum of limonite. The method specifically comprises the following steps: performing X-ray powder diffraction scanning on 18 different batches of samples to obtain an XRDFourier spectrum, screening the batches with relatively large deviation, overlapping and averaging geometric topology graphs of the sample spectrum through Origin8, establishing an XRDFourier reference fingerprint spectrum of limonite, performing peak searching treatment by using MidJade5, screening 13 shared characteristic peaks with relatively large strength, and finally calculating the similarity, wherein the similarity of the samples of different batches is good, various calculation methods have no remarkable difference, thus establishing the XRDFourier standard fingerprint spectrum of limonite. Meanwhile, the invention further provides the XRDFourier standard fingerprint spectrum of limonite established by using the method, and an application method of the spectrum. Due to adoption of the fingerprint spectrum provided by the invention, scientific reference is provided for specimen identification and quality evaluation on a limonite medical material. Besides, main component analysis shows that quartz and alkali ferric oxide are main minerals of limonite.

Description

technical field [0001] The invention relates to a quality control method for mineral drug surplus grain, in particular to a method for establishing an X-ray powder diffraction Fourier fingerprint of mineral medicinal surplus grain, a standard fingerprint spectrum and an application thereof. Background technique [0002] Yu Yuliang (Limonitum) is a commonly used clinical mineral medicine, which was first recorded in "Shen Nong's Materia Medica". The 1990 edition of "Chinese Pharmacopoeia" began to record, and its source is the hydroxide mineral limonite, mainly containing basic iron oxide. It has the effects of astringent intestines, stopping bands and bleeding, and is mainly used to treat chronic diarrhea and dysentery, bloody stool and metrorrhagia, and red and white vaginal discharge embolisms. Clinically, it can treat gastrogenic diarrhea, diarrhea, hematochezia shock, uterine prolapse, anovulatory menstrual infertility, ulcerative colitis, etc. The research and utiliza...
