Metabolite profiling of sesquiterpene lactones and phenolics of bioactive extracts from Asteraceae medicinal plants by HPLC-UV-MS
Poster Nov 03, 2010
Metabolite profiling (HPLC-UV-MS) was performed for extracts from Tithonia diversifolia (Td) and Smallanthus sonchifolius (Ss) leaves [aqueous crude (ACE); leaf rinse (LRE); 70%MeOH rinsed leaves (GFE)]. LREs presented mainly sesquiterpene lactones (SLs) and flavonoids. FGEs and ACEs presented mainly chlorogenic acids. SLs were not detected in GFEs but traces were detected in ACEs. All extracts presented anti-inflammatory potential. LREs were highly toxic while GFEs did not presented significant toxicity.

A Tissue-based Proteomic Study of VEGFR2 in Human Term PlacentasPoster
VEGFR2 is the main regulator of placental angiogenesis and at term is localized in endothelial cells (EC) of the villous vasculature. VEGFR2 immunoprecipitation (IP) of membrane proteins, extracted from the fetal compartment, isolated 30 proteins that were identified by proteomic analysis.READ MORE
