Levatin, an 18-Norclerodane Diterpene from Croton levatii.[Reference: WebLink]

METHODS AND RESULTS:
A new ent-norclerodane diterpenoid named Levatin [1] was isolated from the stem bark of Croton levatii. Its structure was elucidated by means of 2D nmr experiments as ent-15,16-epoxy-18-norcleroda-8(17),13(16),14-triene-19,3:20,12S-diolide.
