T/NAIA 0287-2024 Determination of six flavonoids in Goji berries using liquid chromatography-mass/mass spectrometry (LC-MS/MS) method
Basic Information
Scope
Main technical content: This document specifies the liquid chromatography-mass spectrometry/mass spectrometry method for determining flavonoids in wolfberry. This document is applicable to the determination of rutin, isoquercetin, quercetin-7-O-glucoside, kaempferol-3-O-rhamnoside, 6-methoxyl kaempferol-3-O-rhamnoside, and narcissin in wolfberry by liquid chromatography-mass spectrometry/mass spectrometry. The quantification limits of the method in this document are as follows: the quantification limit of rutin is 1.00 mg/kg, and the quantification limits of isoquercetin and quercetin-7-O-glucoside are both 0.010 mg/kg, and the quantification limits of kaempferol-3-O-rhamnoside, 6-methoxyl kaempferol-3-O-rhamnoside, and narcissin are all 0.050 mg/kg.
