J. Martinez et al., ISOLATION OF 2 FLAVONOIDS FROM TANACETUM-MICROPHYLLUM AS PMA-INDUCED EAR EDEMA INHIBITORS, Journal of natural products, 60(2), 1997, pp. 142-144
The CH2Cl2 extract of Tanacetum microphyllum exhibited antiinflammator
y activity on PMA-mouse ear model. Two antiinflammatory flavonoids, 5,
7-dihydroxy-3,6,4'-trimethoxyflavone (santin) (1) and 5,7-dihydroxy-3,
4'-dimethoxyflavone (ermanin) (2), were isolated.
