The last few decades, many studies are done polyphenolic compounds, hormones because of their biological and pharmacological activities. Hromones are abundant in the plant world from algae to sawmills. To date, hromones found in the nature of the 2-metilderivati ​​and therefore are classified as C 6-C 4compounds. Peucenin, eugenitol isoeugenitol and hormones are the most common in nature (and Hinreiner Geissman, 1952).

From the oil of clove is extracted colorless, crystalline substance known as eugenin (Meijer and Schmid, 2004). Crossosoma bigelovii plants extract were isolated and well-known hromones eugenin noreugenin (Klausmeyer et al., 2009).

Tuntuwachwuttikul et al. (2006) have isolated four new hormones from plants and to perforate Harrisonia: perforamone A, B, C and D in addition to already known: saikohromona, greveihromenola, eugenina.

The two hromones were isolated from Peperomia vulcanica. These are 5-hydroxy-2-(14′-(E)-nonadekenil) hormones (1) and 5-hydroxy-2-[12′-(3 „, 4“-metilenedioksifenil-dodekanil] hormones (2) (Mbah et al., 2002). Research in the Study Phytochemicals De Carvalho et al. (2005) have resulted in the identification of ten new hormones in leaves of Licania arianeae as follows: four 5,7-dihydroxy-2-alkilhromona, four 5,7-dihydroxy -6-chloro-2-alkilhromona and two 5,7-dihydroxy-6 ,8-dichloro-2-alkilhromona.

Bondge (2009) found that hormones in a number of plants involved in the growth cycle and encourage the consumption of oxygen in the tissues. They are photochemically very active (Kumar and Yusuf, 2006).
