Determination of Significance：
Flavonoids are a class of poly-phenyl compounds, which are plant secondary metabolites. They have the advantages of anti-inflammatory, antibacterial, hypolipemic, scavenging hydroxyl free radicals and cancer prevent.
Measurement Principle：
In the alkaline nitrite solution, the flavonoid and the aluminum ion can form a red complex with a characteristic absorption peak at 470 nm. The sample flavonoid content can be calculated by measuring the absorbance of the sample extract at 470 nm.

植物类黄酮检测的样本是一定需要烘干之后进行吗？可否液氮研磨后测定2023-04-08 13:59:00
Administrator新鲜样本建议烘干后称量检测；-80冻存样，可液氮研磨后称量测定，但检测结果有可能低于试剂盒最低检出限，建议依据预实验实际检测结果进行适当的调整。
