Heliotropium

Amongst products isolated from Heliotropium spathulatum (Boraginaceae) were 9 mg of a new alkaloid which gave a positive Ehrlich reaction with p-dimethylaminobenzaldehyde The molecular formula determined by mass spectrometry is CisH2sNOs. What is the structure of the alkaloid given the set of NMR results 54 Reference is useful in providing the solution to this problem. Conditions CDCI3, 9 mg per 0.3 ml, 25 °C, 400 MHz ( //), 100 MHz ( C). (a) HH COSY plot ... [Pg.171]

Attention has been called recently to Amsinckia intermedia as causing liver necrosis in swine, horses and cattle. Like Heliotropium and Tri-chodesma, it belongs to the Boraginacese. ... [Pg.615]

In mammals, phenobarbital and phenytoin increase serum ceruloplasmin concentrations (Aaseth and Norseth 1986). Chronic copper poisoning in sheep is exacerbated when diets contain heliotrope plants (Heliotropium sp., Echium spp., Senecio sp.). Aggravated effects of the heliotrope plants include reduced survival and a twofold to threefold increase in liver and kidney copper concentrations when compared to control animals fed copper without heliotropes (Howell et al. 1991). Rats given acutely toxic doses of 2,3,7,8-tetrachlorodibenzo-para-dioxin had elevated concentrations of copper in liver and kidney because of impaired biliary excretion of copper (Elsenhans et al. 1991). Morphine increases copper concentrations in the central nervous system of rats, and dithiocarbam-ates inhibit biliary excretion (Aaseth and Norseth 1986). In human patients, urinary excretion of copper is increased after treatment with D-penicillamine, calcium disodium EDTA, or calcium trisodium diethylenetriamine penta acetic acid (Flora 1991). [Pg.139]

The Borage plant (syn. Forget-me-not) family (Boraginaceae Lindl.) contains L-ornithine (Figure 11 and 15) derived alkaloids, such as indicine-N-oxide in the heliotrope (Heliotropium indicum) and southern hound s tongue Cynoglosum creticum) species (Table 8).

Figure 98. A diagram of the accumuiation of pyrroiizidine aikaloids in some insect species during various developmentai stages. It shouid be noted that it is not often that these aikaloids are present in the eggs, as in the case of the Arctia caja. Natural sources are pyrroiizidine alkaloid-rich plant species Senecio spp., Homoptera Senecio and Adenostyles spp., Coleoptera and Senecio, Adenostyles, Petasites, Crotalaria and Heliotropium spp., Lep-idoptera).
