Abstract

The invention provides a method for detecting citrinin in Zhibituo tablets, aiming to provide a method for detecting citrinin in Zhibituo tablets with high sensitivity and short detection time; the method comprises the following steps in turn: 1) Preparation of standard solution; 1) Preparation of standard solution; 2) Take 0.5g of Zhibituo tablets and pulverize them, put them in a 10ml Erlenmeyer flask, add 3ml of 1% phosphoric acid-methanol solution, heat and reflux at 60°C for 60min, cool, filter, Transfer the filtrate to a 25ml volumetric flask, dilute to the mark with water, shake well and filter, pass through the HLB solid-phase extraction column activated with 3ml ethanol and 3ml water respectively at a flow rate of 1ml / min, rinse with 5ml water, discard, and then Elute with 5ml of ethanol to collect the eluate, blow the eluate to nearly dry under nitrogen at 40°C, add 1ml of ethanol to dissolve it, and filter it with a 0.22μm organic filter membrane to obtain the sample to be tested. The invention relates to detection by a triple quadrupole liquid phase mass spectrometer; it belongs to the technical field of chemical detection.

Description

technical field [0001] The invention provides a method for detecting citrinin, specifically a method for detecting citrinin in Zhibituo tablets; it belongs to the technical field of chemical detection. Background technique [0002] Citrinin was first isolated from Penicillium citrinum in 1931. Its molecular formula is C 13 h 14 o 5 , the molecular weight is 250.25. Citrinin has certain nephrotoxicity and hepatotoxicity, can cause teratogenicity, cause tumor and induce mutation. Red yeast rice is a traditional Chinese medicinal material, which is cultivated and fermented in rice with a unique monascus mold. Because some Monascus strains can produce statins that inhibit cholesterol biosynthesis, the traditional Chinese medicine Monascus has been developed as Zhibituo Tablets and health food for lowering blood lipids. In 1995, after the French scholar Blanc et al. first discovered that citrinin was contained in red yeast rice products, citrinin has been used as a strict c...
