Evaluation of the Activity of Estragole and 2-Isopropylphenol, Phenolic Compounds Present in Cistus ladanifer

A large number of studies Cistus ladanifer highlight this Mediterranean shrub as a source the phenolic compounds responsible for allelopathic potential species. There are few present in C. that have not yet been studied. The objective work was to evaluate activity estragole and 2-isopropylphenol on filter paper soil monocotyledons (Allium cepa) dicotyledons (Lactuca sativa). results showed when test carried out paper, germination growth L. sativa strongly inhibited by 2 isopropylphenol estragole. an IC50 0.7 mM 0.1 rate, 0.4 size radicle 0.3 hypocotyl. Estragole rate 1.5 1.1 effects these pure A. cepa were lower, assays performed soil, they dissipated. mixture had 0.6 length hypocotyl soil. also with mM. On other hand, it observed stimulated showing hormetic effect EC50 In conclusion, can be said species nature, is essential verify its possible allelochemicals target species, which will exert their action at concentrations found usual environment, addition taking into account interaction medium.
