The Balkan Peninsula plant Achillea depressa contains the previously discussed 260 and its novel hydroxy derivative 274 (521), which is apparently a diastereomer of the known bibsanin (1). Centaurea acaulis from Algeria has afforded 14-chloro-10/ -hydroxy-10(14)-dihydrozaluzanin D (275) (522). The widely distributed medicinal herbaceous perennial plant Cynara scolymus contains the new cynarinin B (276) as one of nine related sesquiterpenoids (523).
