Sažetak
The genus Rhamnus is characterized by the presence of anthraquinones. The total content of madagascin recorded and expressed as µg/g of bark (dry weight) was the following (the content of the free anthraquinone is reported in parenthesis): 28.66 (3.23) for R cathartica, 19.82 (3.23) for R fallax, 7.25 (7.25) for R intermedia, 4.93 (2.17) for R orbiculatus, 19.28 (5.18) for R pumila, 12.72 (12.72) for R rupestris, and finally 5.75 (1.55) for R. saxatilis. On the other hand 3- geranyloxyemodin was revealed only in one species, namely R. saxatilis, exclusively in its glycosidated form, being the recorded total content in this plant 7.37 µg/g.
