New localities of some rare and floristically interesting species in the Dinaric Mountains are listed in the paper. Daphne cneorum L. was previously found in the hinterland mountains of the town of Rijeka, Paeonia mascula (L.) Mill. on Mt Velebit, Rhamnus pumila Turra on Mt Obruč and Mt Risnjak, Sorbus chamaemespilus (L.) Crantz on Mt Obruč and Mt Velebit, and Salix waldsteiniana Willd. on Mt Risnjak.

We determined the content of biologically active compounds in the bark of seven Rhamnus L. and two Frangula Mill. species growing in Croatia. All taxa tested had high content of total polyphenols (from 2.68% in R. orbiculata Bornm. to 8.50% in R. pumila Turra), moderate content of glucofrangulins (from 0.22% in R. pumila to 9.26% in R. fallax Boiss.), nontannic polyphenols (from 0.73% in R. orbiculata to 5.92% in F. alnus Mill.) andtannins (from 1.10% in R. saxatilis Jacq. to 4.92% in R.alaternus L.), and low content of phenolic acids (from0.44% in R. orbiculata to 1.81% in R. intermedia Steud. & Hochst.) and flavonoids (from 0.02% in F. alnus to1.44% in R. pumila). By ANOVA, variability was highest for glucofrangulin content, less for flavonoids, phenolicacids and nontannic polyphenols, and least for total polyphenols and tannins. © Polish Academy of Sciences and Jagiellonian University, Cracow 2010.
