  • Title: Ecdysteroids from Vitex species: distribution and compilation of their 13C-NMR spectral data.
    Author: Sena Filho JG, Duringer J, Maia GL, Tavares JF, Xavier HS, da Silva MS, da-Cunha EV, Barbosa-Filho JM.
    Journal: Chem Biodivers; 2008 May; 5(5):707-13. PubMed ID: 18493957.
    Abstract:
    Iridoids and ecdysteroids are found in some genera of the family Verbenaceae. In such cases, they are used as chemotaxonomic markers for the difficult task of taxonomic identification by using morphological characteristics of plants belonging to this family. The present work describes the distribution of ecdysteroids in plants from the genus Vitex from a review of previous work on seventeen Vitex species. In addition, (13)C-NMR data of the main ecdysteroids found in this genus are described. This study attempted to summarize previous research on ecdysteroids distribution in Vitex species with the addition of (13)C-NMR analysis to further refine the characterization of these compounds in the Verbenaceae family.
