Abstract

The invention belongs to the technical field of medicine powder X-ray diffraction analysis, and particularly relates to an extraction method and application of an X-ray diffraction fingerprint spectrum of borneol in tin powder. According to the method for extracting the X-ray diffraction fingerprint spectrum of the borneol, the X-ray diffraction spectrum of tin powder before and after volatilization treatment is measured by utilizing the volatility of the borneol, and the X-ray diffraction spectrum of the borneol is extracted by utilizing the difference of the spectrum, so that the extraction of the X-ray diffraction spectrum of a single component in a complex mixture is realized; the method is applied to identification of borneol in tin powder.

Description

technical field [0001] The invention belongs to the technical field of drug powder X-ray diffraction analysis, and in particular relates to an extraction method and application of a borneol X-ray diffraction fingerprint. Background technique [0002] The first appearance of Xi Lei San was recorded in You Yi's "Golden Chamber Wings" in the Qing Dynasty under the name of "Rotten Throat Sha Fang". Its formula is ivory scraps, indigo naturalis, wall money charcoal, human nails, pearls, borneol, and bezoar. As a classic famous prescription, Xi Lei Powder has been widely used by physicians in various clinical fields such as ENT, fever, gynecological diseases, digestive system diseases, and tumors. [0003] The borneol in the tin powder is a white translucent crystal, the ivory is an animal medicine for horns, the pearl is an animal medicine for shellfish, and the bezoar is an animal medicine for the calculus. , while excess lime remains in the form of calcium hydroxide. In X-ra...
