Trachylobanoic acids

PONCE-MONTER, H., CAMPOS, M.G., AGUILAR, I., DELGADO, G Effect of xanthorrhizol, xanthorrhizol glycoside and trachylobanoic acid isolated from Cachani complex plants upon the contractile activity of uterine smooth muscle., Phytother. Res., 1999,13,202-205. [Pg.308]

Homeosoma electellum) contain high concentrations of tra-chyloban-19-oic acid (70) and ( —)-16-kauren-19-oic acid (71) in their florets. As sunflower florets that contain only small amounts of these compounds are a major portion of the diet of first instar larvae of this insect, it is likely that these acids serve as feeding inhibitors. At the 1% level, both kaurenoic and trachylobanoic acids decreased the growth of sunflower moth larvae and tobacco budworm (Heliothis virescens) by about 50%. At the 0.5% level, both reduced larval growth of the cotton bollworm and the pink bollworm to less than 5% (Fig. 22.23) (Mabry and Gill, 1979). The Z-and -isomers of (- )-ozic acid (72) have been isolated from Helianthus occidentalis and may be associated with resistance to insect attack (Stipanovic et al., 1979). [Pg.416]
