Plant sesquiterpene lactones. [PDF]

Philos Trans R Soc Lond B Biol Sci
Sesquiterpene lactones (STLs) are a prominent group of plant secondary metabolites predominantly found in the Asteraceae family and have multiple ecological roles and medicinal applications. This review describes the evolutionary and ecological significance of STLs, highlighting their roles in plant defence mechanisms against herbivory and as ...

Sesquiterpene lactones. Part XXII. Sesquiterpene lactones in Species of the Genus Chrysanthemum

Acta Societatis Botanicorum Poloniae, 1978
A method of effective study on sesquiterpeine lactones in unknown plant material was worked out. This method allows the choice of species with high sesquiterpene lactones content and interesting chemical composition. Studies were carried out on 14 species of <i>Chrysanthemum</i> s.l..

Purification, Fluorescent Labeling, and Detyrosination of Mammalian Cell Tubulin for Biochemical Assays

Cytoskeleton, EarlyView.
ABSTRACT Microtubules play essential roles in numerous cellular processes. All microtubules are built from the protein tubulin, yet individual microtubules can differ spatially and temporally due to their tubulin isotype composition and post‐translational modifications (PTMs).

Integrated phytochemical and bioactivity profiling of Xanthium strumarium fruits from Korea and China: Implications for origin‐specific quality specification

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Geographic origin influences the phytochemical composition and biological activities of medicinal plant resources. Xanthium strumarium L. (XS) fruit is widely used in East Asian traditional medicine. However, current pharmacopeial standards primarily recognize Chinese‐derived material, despite the availability and traditional use of

Dehydrobrachylaenolide: an eudesmane-type sesquiterpene lactone [PDF]

Acta Crystallographica Section E Structure Reports Online, 2008
The three-ring eudesmanolide, C(15)H(16)O(3), is a natural product isolated from Dicoma anomala Sond. (Asteraceae). The compound contains an endo-exo cross conjugated methyl-enecyclo-hexenone ring with an envelope conformation trans-fused with cyclo-hexane and trans-annelated with an α-methyl-ene γ-lactone.

Unsaturated biobased polyesters from bicyclic α‐pinene‐based diols

Polymer International, EarlyView.
We present the synthesis of four biosourced unsaturated polyesters made from chiral terpene‐based diols and esters of renewable diacids. The resulting materials harbor a bicyclic pinene ring in their backbones which leads to enhanced thermal properties while still conferring susceptibility to enzyme hydrolysis for chains having a cis alkene.

Testing optimal defense theory: Root resistance selection in chicory (Cichorium intybus) reduces foliar defense and alters aphid performance and feeding behavior

Pest Management Science, EarlyView.
Root‐focused resistance in chicory reduces defenses in leaves, impairing root aphids but enhancing foliar aphid performance. Selecting root resistance can create unintended trade‐offs across plant organs. Abstract BACKGROUND Plants are constantly exposed to a wide range of herbivores at both aboveground (AG) and belowground (BG) levels, involving ...
