Abstract: It is of great significance for developing high-valued black goji products to determine its flavonoid composition and structures. The supercritical CO2 extract of black goji was analyzed by ultra-high performance liquid chromatography & mass spectrometry (UPLC-MS), Peakview work station matching, two-dimensional mass spectrometry, ultraviolet spectrum and mass spectral data comparison, to illustrate the flavonoid composition and structures. 13 flavonoid chemicals were determined, i.e. 7 flavonol aglycones and flavonol glycosides, 3 dihydroflavonol aglycones, 2 flavonoid aglycones and 1 dihydroflavonoid aglycon, including rutin, quercetin-3-β-glucuronide, hyperoside i.e. quercetin-3-O-galactopyranoside, dihydroquercetin, dihydroisorhamnetin, dihydrogen Kaempferol, quercetin, apigenin, hesperetin, alizarin, kaempferol, isorhamnetin, kaempferide, among which hesperetin and alizarin are never found in black goji.

Key words: Black goji, Flavonoid, Supercritical CO2 extract, Ultra-high performance liquid chromatography and mass spectrometry (UPLC-MS)
