This study was aimed to study the chemodiversity of flavonoids in the Formosan Litsea and Neolitsea plants. Applications of LC‐SPE‐NMR and LC/MS hyphenated techniques in analyzing polar constituents from the leaves of L. acuminata , L. hypophaea , N. acuminatissima , and N. konishii led to the identification of 13 known flavonoids and one new flavonol dioside, quercetin 3‐ O ‐(2‐ O ‐β‐ D ‐apiofuranosyl)‐α‐ L ‐rhamnopyranoside. The quantity and variety of flavonoid composition in the leaves of 12 Litsea and Neolitsea plants were examined to enable more effective utilization of such bioactive ingredients. Of these, N. acuminatissima was found to contain the most quantity of flavonoids ( ca . 0.24%leaves).
