Holcocerus Hippophaecolus

Volatile compounds of healthy and insect-damaged stems of Hippophae rhamnoides sinensis were analysed using dynamic headspace and thermal-desorption cold-trap injector gas chromatography/mass spectroscopy (TCT-GC/MS). Sixteen compounds, belonging to alkanes, alcohols, aldehydes, esters, ketones, and ethers, were identified in the stems of healthy H. rhamnoides sinensis; the compounds in H. rhamnoides sinensis occurring naturally or cultivated in plantations were similar, but the relative contents were significantly different. In plants damaged by Holcocerus hippophaecolus, the nature and content of the volatile compounds were greatly changed. Butanedione and butyl glyoxylate were newly generated after damage by the pest, and the relative levels of pentanal, heptanal, eucalyptol, terpineol, and camphor were sharply increased in both naturally occurring and plantation-grown plants. n-Decane, trans-2-nonen-1-ol, and n-hexadecane levels increased in plants cultivated in the plantation and decreased in natural forests, whereas the levels of other types were reduced. Thus, both the nature and the content of volatile compounds of H. rhamnoides sinensis are affected by H. hippophaecolus damage, providing a theoretical basis to identify the mechanism of pest destruction

Smith Model

Hyperbrached poly(ester)s derived from naturally-occurring biomonomers may serve as excellent platforms for the sustained-release of therapeutics. Those generated from glycerol are particularly attractive. Traditionally, the difference in reactivity of the hydroxyl groups of glycerol has precluded the formation of well-defined polymers at high monomer conversion without gelation. Using the Martin-Smith model to select appropriate monomer ratios (ratios of functional groups), polymerization may be carried out to high conversion while avoiding gelation and with the assurance of a single type of endgroup. Various agents may be attached via esterification, amide formation or other process. Sustained release of the active agent may be readily achieved by enzyme-catalyzed hydrolysis.

Pyrrolizidine alkaloid derivatives are present in the androconial (male scent) organs of Prittwitzia hymenaea, Mechanitis isthmia veritabilis, Tithorea harmónia fúria (Lep., Ithomiinae), Amauris echeria and Euploea sylvester (Lep., Danainae). While the ithomiines contain the new pyrrolizidine alkaloid derivative methyl hydroxydanaidoate, the danaines contain the known derivatives danaidone and hydroxydanaidal. In addition, 2,2,6-trimethyl-2-cyclohexen-1,4-dione (oxoisophorone) and related terpenoids have been identified from Amauris, Euploea and Prittwitzia as well as from the flowers of Buddleja davidii (Loganiaceae). Three new naturally occurring bishomoterpenes as well as mono- and sesquiterpenes and aromatic compounds add to the formation of species specific blends in the scent organs of the butterflies
