title: Sesquiterpene lactones from glandular trichomes of Viguiera radula (Heliantheae; Asteraceae).
abstract: In addition to known compounds, the floral parts of Viguiera radula afforded two new sesquiterpene lactones. All compounds were detected in glandular trichomes, which were micromechanically collected from the anther appendages and analyzed by HPLC. Structure identification was performed by NMR and MS techniques.
