Terpene lactones are effective medicinal active ingredients in Ginkgo biloba leaves, which have effects on the immune system and central nervous systemIt has a protective effect against ischemic injury and has anti shock, anti allergic, and anti-inflammatory effects. Due to the UV absorption of terpenoid lactonesWeak, with strong interference from flavonoids, making it inconvenient to use UV detectors. Evaporative light scattering detectionAs a universal detector, the sample does not need to have optical absorption characteristics and has good sensitivity and selectivity,Therefore, it is often used for the determination of ginkgolide components. The Chinese Pharmacopoeia adoptsHPLC-ELSDMethod for Ginkgo Leaf LeavesQuality control of terpenoid lactones. This experiment is conducted according to20 The detection of terpenoid lactones in Ginkgo biloba leaves in the Chinese PharmacopoeiaThe method of measurement was used to analyze the content of terpenoid lactones in Ginkgo biloba leaves, and good analysis results were obtained.
