According to a study published by "Journal of ethnopharmacology", all the roots, stems, leaves, flowers, and fruits of Tilia tuan Szyszyl. have been used medicinally by the folk Bai and Yi people in Yunnan province, China, to treat inflammation, rheumatism and pain. This study focused on investigating the main anti-inflammatoy constituents of T. tuan flowers. Twenty-two compounds were identified from T. tuan flowers for the first time, including 10 flavonoids (1-10), 7 phenylpropanoids (11-17), 3 triterpenoids (19-21), 1 sterol glucoside 18, and 1 glyceride 22. Among these, compounds 1, 5, 7, 8, 10, 17, and 22 exhibited remarkable anti-inflammatoy activity against NO production with a range of 5.2-34.5 μM. The results show that flavonoids including the new compound 1 and the phenyl-propanoid are the primary active constituents of T. tuan flowers.
