A new labdane diterpenoid arabinoside from Conyza blinii.
A new diterpenoid glycoside, 14,15-dinor-labdan-13-one-8-O-alpha-L-arabinopyranoside (1), was isolated from Conyza blinii. The structure of this new arabinoside was elucidated on the basis of extensive NMR and HRMS spectroscopy. In addition, the presence of 3R-hydroxyoctadecanoic acid in C. blinii was reported for the first time.
