Iridoid monoterpenes

Since the biosynthesis of iridoid monoterpenes in insects has been shown to... [Pg.250]

Some volatile iridoid monoterpenes with biological activity are also found in essential oils and in insect pheromonal and defensive substances. Eisner ( ) found that 17 species of insects were repelled by the iridoid monoterpene nepetalactone. Lacewings (Chrysopa septempunctata) are attracted by the leaves and fruits of Actinidia polyqama (Actinidiaceae) which contain a series of volatile iridoid monoterpenes (67). [Pg.310]

Several non-volatile iridoid monoterpenes occur as glycosides and have been observed to have biological activity. For example, xylomolin, from the unripe fruits of Xylocarpus moluccensis Roem. (Meliaceae) has antifeedant activity against Spodoptera exempta an African armyworm at 100 ppm ( ) and crotepoxide from Croton macrostachys (Euphorbiaceae) possesses antifeedant activity against Spodoptera exempta (85). [Pg.313]

The iridoid monoterpenes, catalpal and catalposide occur in nectar in flowers of Catalpa speciosa (Bignoniaceae) and are toxic to many non-coadapted insects which attempt to rob nectar. The bees which normally pollinate this plant are relatively insensitive to the effects of these compounds (88). [Pg.314]

A quite unusual prunasin derivative, in which the prunasin moiety is attached to an iridoid-monoterpene, was found in Canthium schimperianum (Schwarz et al, 1996). The biological significance of these complex structures is still unknown. Their structures are comprehensively reviewed by Seigler (1991) and Muller and Seigler (1998). [Pg.98]

The conversion of a bicyclo[2.2.1]octenone derivative to the corresponding bicyclo[3.3.0]octenone, a common intermediate in the total synthesis of several iridoid monoterpenes, was achieved by N.C. Chang et al. The target was obtained by sequential application of the Corey-Chaykovsky epoxidation, Demjanov rearrangement and a photochemical [1,3]-acyl shift. [Pg.103]
