Ruta graveolens

Ruta graveolens (Rutaceae) and its tissue cultures are investigated from a wide variety of aspects, such as botanical studies, medicinal activities, chemical constituents and biosynthesis of some compounds. The in vitro culture of Ruta, quick-growing and with strong biogenetic potentialities, is an optimal implement for biochemical and physiological studies, and many research teams are using it in various fields which are reported in this chapter. Distribution and Importance of the Plant The genus Ruta belongs to the family Rutaceae, subfamily Rutoideae and tribe Ruteae. The subtribe Rutinae contains the following genera: Ruta L., Haplophyllum A. Juss., Thamnosma Torr. and Fr. and Boenninghausenia Reichb. Engler (1931) included Ruta and Haplophyllum in one genus. However, Waterman (1975) found that from a chemical standpoint Haplophyllum and Thamnosma are similar, but quite different from Ruta. According to the Flora Europaea, five species are assigned to the genus Ruta (). Ruta graveolens L. (common names: Engl.: common rue, herb of grace; French: rue fetide; German: Gartenraute; Spanish: ruda, arruda) is a well-known evergreen, half shrubby plant of 0.5 to 1 m in height, with leaves two- to three-pinnate and Read more […]
