What is Baicalin?

Baicalin is a kind of flavonoid extracted and isolated from the dried root of scutellaria baicalensis georgi. Baicalin dissolves in alkali and ammonia and turns yellow at first, then turns black and brown soon. Baicalin has the effects of anti-tumor, anti-pathogen and anti-allergic reaction, and has a protective effect on liver injury, the improvement of diabetic nephropathy, the repair and protection of brain injury, and also has a certain effect on retinopathy. It can be used for bacteriostasis, diuresis, anti-inflammatory, cholesterol-lowering, anti-thrombosis, easing asthma, detoxification, hemostasis and anti-allergic reaction. Baicalin has a wide range of uses, and it is very important to establish an analytical method for baicalin in plant metabolites.

Creative Proteomics provides the simple, rapid, accurate, affordable and highly automated analytical method and equipment to analyse baicalin. High performance liquid chromatography with diode array detection and mass spectrometer (HPLC-DAD-MS) can solve some of the problems associated with baicalein analysis. Improved extraction and purification steps can also increase the sensitivity of the analytical method.

How Can Creative Proteomics Support Your Baicalin Analysis?

Understanding the pharmacokinetics, bioavailability, and metabolism of baicalin is an indispensable task, rooted in the need to develop drugs based on this particular compound. We used liquid chromatography-mass spectrometry (LC-MS) to identify, quantify and characterize baicalin and its metabolites in biological samples. Liquid chromatography-mass spectrometry proved to be highly efficient in separating baicalin from complex matrices (e.g. blood, urine, or tissue samples), in addition to detecting its molecular weight and fragmentation patterns, providing valuable structural and metabolic information.

The LC-MS analysis of baicalin is a multi-step process that starts with the extraction of the compound from biological samples by using a suitable solvent, followed by separation on a chromatographic column, and finally by mass spectrometry for detection and quantification.

Our experienced team of scientists has extensive expertise in the analysis of baicalin and other natural products using state-of-the-art LC-MS instrumentation and software. We offer a wide range of baicalin analysis services, including:
