PARTE UTILIZADA= Used part: Rizoma.

ACCIÓN FARMACOLÓGICA= Pharmacological action: Aromatizante de tabaco (rizoma), estomáquico. 

COMPOSICIÓN QUÍMICA= Chemical composition: From aerial parts of Trychocline reptans Wedd.: 6-acetyl-5-hydroxy-2-isopropenyl-2,3-dihidrobenzofurane, 7-O-isopropenyl coumarin, marmesin, umbelliferone, and the linear furanocumarins: bergapten, cnidilin, imperatorin, isopimpinellin, psoralen, trichoclin and xanthotoxin were isolated.

ÚLTIMOS AVANCES EN LA QUÍMICA Y ACTIVIDADES BACTERIOLÓGICAS EN LAS PLANTAS MEDICINALES= Medicinal plants, last advances on chemistry and bacteria activities on the medicinal herbs

Phytotoxic activity of the 6-acetyl-5-hydroxy-2-isopropenyl-2,3-dihydrobenzofuran, isolated from Trichocline reptans (Asteraceae), was investigated in two weed species.  The best growth inhibition was on Chenopodium album, with less activity on Sorghum halepense.
