Trypanocidal Activity of Smallanthus sonchifolius: Identification of Active Sesquiterpene Lactones by Bioassay-Guided Fractionation
In order to find novel plant-derived biologically active compounds against Trypanosoma cruzi, we isolated, from the organic extract of Smallanthus sonchifolius, the sesquiterpene lactones enhydrin (1), uvedalin (2), and polymatin B (3) by bioassay-guided fractionation technique. These compounds showed a significant trypanocidal activity against the epimastigote forms of the parasite with IC50 v...
متن کاملPurification and identification of antimicrobial sesquiterpene lactones from yacon (Smallanthus sonchifolius) leaves.
The extraction of yacon [Smallanthus sonchifolius (Poepp. and Endl.) H. Robinson; Asteraceae] leaves and chromatographic separation yielded two new antibacterial melampolide-type sesquiterpene lactones, 8beta-tigloyloxymelampolid-14-oic acid methyl ester and 8beta-methacryloyloxymelampolid-14-oic acid methyl ester, as well as the four known melampolides, sonchifolin, uvedalin, enhydrin and fluc...
متن کاملBioassay Guided Fractionation of Allium austroiranicum by Cytotoxic Effects against Ovary and Cervical Cancer Cell Lines
Background and objectives: Cancer is a major health problem in the world. The aim of this study was to extract the flowers of Allium austroiranicum used by Iranian people as a condiment or for its medicinal effects followed by bioassay guided fractionation of the extracts and fractions, using anti-proliferative effects against ovarian and cervical cancer cells. <strong...
متن کاملEvaluation of the antiproliferative activity of the leaves from Arctium lappa by a bioassay-guided fractionation.
Arctium lappa L. (Asteraceae) is used in folk medicine around the World, and shows several kinds of biological activity, particularly in vitro antitumor activity in different cell lines. This study evaluated the antiproliferative activity of the crude extract, semipurified fractions, and isolated compounds from the leaves of A. lappa, through bioassay-guided testing in Caco-2 cells. The crude e...
متن کاملA biosynthetic pathway of sesquiterpene lactones in Smallanthus sonchifolius and their localization in leaf tissues by MALDI imaging.
The biosynthetic route for epoxyangelate esters of the sesquiterpene lactones (STL) uvedalin and enhydrin from in vitro cultures of Smallanthus sonchifolius (Asteraceae) was investigated with (13)C-precursors for the first time in the literature. Photomicroscope analyses and studies using MALDI-MS imaging confirmed that glandular trichomes accumulate STL.
