An analytical method was developed to determine the concentrations of four flavonoids found in Morinda citrifolia leaves. The contents of the rutin, kaempferol-3-O-a-l-rhamnopyranosyl-(1→6)-b-d-glucopyranoside, quercetin, and kaempferol in the noni leaves varied from 1.16 to 371.6mg/100g dry weight.  (view original abstract at https://www.ncbi.nlm.nih.gov/pubmed/26047461).
