“…Tephrosia (Papilionaceae), a large genus of perennial plants, distributed in the tropical and sub-tropical regions, is a rich source of flavonoids, isoflavonoids and rotenoids and exhibits insecticidal, fishpoisoning and medicinal properties [1][2][3][4]. The presence of cancer chemopreventive flavonoids in T. toxicaria has recently been reported [5].…”
The essential oils obtained by hydrodistillation of the leaves, stems, and shoots of Tephrosia toxicaria Pers (Papilionaceae) were analyzed using GC and GC/MS. Germacrene D was the major component (20.7-33.3 %) of the oils of leaves and shoots, whereas spathulenol was the main constituent (42.3%) of the stem oil. The essential oils from the leaves and stems, when tested for activity against mosquito larvae (Aedes aegypti), gave LC 50 values of 81.3 ± 2.9 and 63.1 ± 1.0 ppm, respectively.

“…During the period 1995-1997 some 15 new isoprenylated flavones have been reported, including a variety of structures from simple prenyls to ring closed furano and pyrano derivatives. [73][74][75][76][77][78][79][80][81][82][83][84][85] Some of the more exotic structures are illustrated, i.e. 21-31.…”

Abstract:The genus Tephrosia, belonging to the Leguminosae family, is a large pantropical genus of more than 350 species, many of which have important traditional uses in agriculture because they possess the bioactivity of phytoalexins. This review not only outlines the sources, chemistry and biological evaluations of natural products from the genus Tephrosia worldwide that have appeared in literature from 1910 to December 2013, but also covers work related to proposed biosynthetic pathways and synthesis of some natural products from the genus Tephrosia, with 105 citations and 168 new compounds.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
