Screening and determination of effective components in Compound Suanzaoren Decoction based on network pharmacology

This article intended to build a component-target network to screen the effective components of Compound Suanzaoren Decoction, and to establish an efficient and rapid method for the determination of effective components. 103 compounds in the Compound Suanzaoren Decoction were identified by HPLC-Q-TOF MS/MS. 27 potential effective substances were analyzed by network pharmacology. The first six components with the largest degree were selected as effective components, including neomangiferin, mangiferin, ferulic acid, senkyunolide I, spinosin, and 6'''-feruloylspinosin. A UHPLC method was established for determination. The chromatographic separation was performed on a Waters CORTECS T3 column (2.1 mm×150 mm, 1.6 μm) with the mobile phase of 0.1% phosphoric acid solution and acetonitrile. The results showed that the specificity was good with no interference for the chromatographic peaks. The linear was excellent within the scope of investigation, with the values of r higher than 0.999 0 for all analytes. The method had been verified to have good sensitivity, precision, accuracy, durability and stability. Therefore, the results showed that the method established was suitable for the screening and determination of effective components in Compound Suanzaoren Decoction, which provided a basis for the quality evaluation of traditional Chinese medicine.
