Abstract
The invention relates to a rapid screening method of a plurality of chemical components illegally added in Chinese patent medicine. The rapid screening method comprises the following steps: firstly, preparing a reference solution and a sample solution; respectively sucking the reference solution and the sample solution; dripping on the same silica gel thin layer plate; adding a developing agent for ascending development; taking out and drying in the air; respectively placing below an ultraviolet lamp and observing thin-layer chromatogram; spraying sulfuric acid-ethanol solution; placing in an oven and heating at a constant temperature until spots on the thin layer plate are clear; respectively placing the thin layer plate below the ultraviolet lamp and observing thin-layer chromatogram; and determining that the sample result is positive if fluorescence quenching spots, fluorescence spots or spots with the same color occur at the same time at a point with a retardation factor value same as that of the reference. Obviously, the method provided by the invention is simple to operate, rapid, and cost-effective, not only solves the problem of false positive interference, but also avoids expensive cost and plenty of time consumed by the conventional infrared spectroscopy, HPLC-MS and the like, thereby making it possible to effectively monitor whether chemical components are illegally added in the Chinese patent medicine Xiaohuoluo pills.
Description
Technical field [0001] The invention relates to the field of quality detection of traditional Chinese medicines, in particular to a rapid screening method for multiple illegally added chemical components in Chinese patent medicines. Background technique [0002] Xiaohuoluo Pill is a traditional Chinese medicine preparation composed of six Chinese herbal medicine pieces: Dannanxing, Sichuan Wu, Caowu, Dilong, Frankincense (made), and Myrrh (made). The main effects are dispelling wind and cold, resolving phlegm and dampness, promoting blood circulation and relieving pain. It is used for arthralgia caused by wind, cold and dampness, phlegm and stasis blocking the collaterals. Symptoms are limb joint pain, or cold pain, or tingling, or pain at night, poor joint flexion and extension, numbness and contracture. The preparation method is to pulverize Dannanxing, Chuanwu, Caowu, Dilong, Frankincense (preparation), and Myrrh (preparation) into fine powders, sieving, and mixing, and addin...
