Small‐scale analysis of phytoecdysteroids in seeds by HPLC‐DAD‐MS for the identification and quantification of specific analogues, dereplication and chemotaxonomy

Introduction Phytoecdysteroids are analogues of arthropod steroids occurring in plants. They contribute to invertebrate deterrence. A wide diversity of ecdysteroids occurs in phytoecdysteroid‐containing plant species, sometimes in high amounts. Ecdysteroids demonstrate potentially useful pharmace…
