How many bioactive compounds were systematically identified in vine tea, and how were they classified?

Label:chem

Topic
Vine tea has been used as a detoxifying beverage in China for centuries, but a comprehensive profile of its bioactive constituents was lacking.
Answer
A total of 36 bioactive compounds were identified. They were classified into 11 types: 2 chromones (noreugenin, 3,5,7-trihydroxychromone), 15 flavonoids (e.g., ampelopsin, quercetin, myricetin), 4 phenolic acids (gallic, syringic, ellagic, 3,4-dihydroxy-5-methoxybenzoic), 5 tea polyphenols (EGC, EGG, GCG, ECG, CG), 3 chalcones (phloridzin, phloretin, naringenin chalcone), 1 stilbene (polydatin), 2 lipids (myristic acid, ethyl stearate), 1 sugar (D-gluconic acid), 1 amino acid (L-tryptophan), 1 triterpenoid (oleanolic acid), and 1 alkaloid (jervine).
