    Effect ofSolanum Glycoalkaloids on Potato Aphid,Macrosiphum euphorbiae (1997)

    Notes: Abstract Macrosiphum euphorbiae, also known as the potato aphid, is a potato virus vector, associated with decreased tuber production. Feeding, toxicity, and reproductive effects of the major potato glycoalkaloids (α-chaconine and α-solanine), their common aglycone (solanidine), and a nonpotato glycoalkaloid (α-tomatine) and its aglycone (tomatidine) onM. euphorbiae were studied. As expected, neither α-chaconine nor α-solanine had a strong lethal effect on the aphid, but α-chaconine stimulated feeding at low concentrations. Both aglycones were deterrent and lethal at high concentrations and, like α-chaconine and α-tomatine, they delayed the appearance and decreased the number of nymphs.

    Effect of Solanum Glycosides on the Aphid Schizaphis graminum (1999)
    Springer
    Journal of chemical ecology 25 (1999), S. 369-374 
    Details
    ISSN: 1573-1561
    Keywords: Schizaphis graminum ; Aphididae ; aphids ; greenbug ; survival ; glycosides ; glycoalkaloids

    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract Common Solanum glycosides were tested against a non-Solanum pest, the greenbug, Schizaphis graminum, fed by artificial diet supplemented with the tested compounds. In contrast with the potato aphid Macrosiphum euphorbiae, S. graminum is sensitive to both potato and tomato glycoalkaloids, as well as to all the different Solanum steroidal glycosides tested. S. graminum was less sensitive to glycoalkaloids than to the steroidal glycosides. Laxumin A (LC50 4.3 μM) and laxumin B (LC50 6.1 μM), isolated from Solanum laxum, were the most active of the tested compounds. The different sensitivity of both aphids against Solanum glycosides could be related to a possible adaptation of the insects to their host plants secondary metabolites.

    Effect of Solanum Glycoalkaloids on Potato Aphid, Macrosiphum euphorbiae: Part II (2000)
    Springer
    Journal of chemical ecology 26 (2000), S. 1113-1121

    ISSN: 1573-1561
    Keywords: Macrosiphum euphorbiae ; potato aphid ; Homoptera ; Aphididae ; Solanaceae ; glycoalkaloids ; bioassay ; commersonine ; demissine ; solamargine ; solasodine ; solasonine

    Notes: Abstract We report the deterrent, toxic, and antireproductive effect of several Solanum glycoalkaloids on the potato aphid, Macrosiphum euphorbiae, and discuss the structure–activity relationship of the tested compounds. The results indicate a structure-dependent biological effect of the glycoalkaloids, suggesting that, while the structure of the aglycone defines a basal biological effect, the carbohydrate moiety is crucial for the overall biological effect.

    Glycoalkaloids of Solanum commersonii Dun. ex Poir (1997)
    Springer
    Euphytica 95 (1997), S. 195-201 
    Details
    ISSN: 1573-5060
    Keywords: Solanum ; tomatine ; commersonine ; demissine ; dehydrocommersonine ; dehydrodemissine
    Source: Springer Online Journal Archives 1860-2000
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Abstract Five glycoalkaloids were identified from the aerial parts of wild Solanum commersonii Dun. ex Poir growing in Uruguay and their structures elucidated mainly by chemical and spectroscopic methods. In addition to the already known commersonine, demissine, tomatine and dehydrocommersonine, a new glycoalkaloid, identified as δ5-demissine, solanid -5-en-3-O- {β-D-Glcp-(1→2)-[β-D-Xylp-(1→3) ]β-D-Glcp-(1→4)-β-D-Galp } was found. Tomatine and dehydrocommersonine have not been reported earlier as components of this plant. The glycoalkaloid composition found in the wild plants studied differ significatively from those described earlier, and have some implications in taxonomy and its use in potato breeding.
