| Abstract: | Pieris napi oleracea, an indigenous butterfly to North America lays eggs on Alliaria petiolata, an invasive weed introduced from Europe, but the larvae generally do not survive. A new apigenin glycoside, isovitexin 6"-O-glucoside has been isolated from the leaves A. petiolata and identified as a feeding deterrent for P. napi fourth instar larvae. The structure was elucidated by UV, MS and NMR spectroscopy.SP$ISSN: 0031-9422SP$VOLUME: 47SP$ISSUE: 7SP$PAGE1: 1237 |
