  • Publication number: 20240044851
    Abstract: A method for detecting the content of active ingredients of a compound Sophorae flavescentis radix injection and the fingerprint spectrum thereof. The method comprises using high performance liquid chromatography to perform detection, wherein the high performance liquid chromatography is operated under the condition of a C18 chromatographic column, and active ingredients comprise matrine, oxymatrine, macrozamin, sophocarpine, oxysophocarpine, sophoridine, or/and piscidic acid. The present method is an improved method for performing detection on a compound Sophorae flavescentis radix injection, by means of same, seven ingredients in the compound Sophorae flavescentis radix injection can be simultaneously determined, and a chromatographic fingerprint spectrum can be constructed, thereby providing a technical method for quality control of a compound Sophorae flavescentis radix injection.

  • Publication number: 20240019408
    Abstract: A method for detecting the monosaccharide and oligosaccharide content and fingerprint spectrum of a compound Sophora flavescens injection, comprising: carrying out detection by using a high-performance liquid chromatography-evaporation light scattering detection method, wherein the monosaccharides and oligosaccharides are D-anhydrous glucose, D-fructose, sucrose and pinitol. The present method is an improved method for detecting monosaccharides and oligosaccharides of a compound Sophora flavescens injection, and can measure four saccharide components in the compound Sophora flavescens injection at the same time, and constructs an HPLC-ELSD fingerprint spectrum to provide a technical method for the quality control of the saccharide components in the compound Sophora flavescens injection.
