The content of alkaloids and flavonoids and the yield of herb were analyzed in greater celandine cultivar ‘Cynober’ during six following phases: spring rosette formation, the beginning of flowering, full bloom, green fruit, seed harvest, fall rosette formation. Yield of celandine herb was different at the investigated phases and in years of cultivation. The highest yield of herb was observed at the beginning of flowering, then a decrease was noticed, up to the phase of seed harvest, when the yield grown up. The lowest yield of celandine herb was obtained in last phase – fall rosette formation, except 2011 when the lowest yield was in spring rosette formation. The average content of alkaloids was the highest in phase of green fruit (1.097%), while in 2012, the highest content was reached in phase of fall rosette formation – 1.200%. The lowest content of alkaloids was obtained in herb of the beginning of flowering (0.608%) in both years. The mean content of flavonoids was from 0.310% (the beginning of flowering) to 0.522% (seed harvest) and was the same in both years. The stable high content of total alkaloids and flavonoids and individual alkaloids was noticed in phase of fall rosette. Our results suggest that seed maturity is the best time for celandine herb harvest regarding the herb yield and content of alkaloids and flavonoids.

Introduction: Our study is a part of a trend of studies on the antioxidative properties of Chelidonium majus extracts or their fractions suggesting that antioxidant activities may depend on total flavonoid and/or alkaloid contents. Objective: This study focused on the examination of antioxidative activities of full water extract, non-protein fraction and protein fraction of the extract from aerial parts of mature plants and young seedlings. Methods: Total flavonoid and alkaloid contents were evaluated by spectrometric methods. Quantitative determination of chelidonine, coptisine, sanquinarine, berberine was made by HPLCUV. The antioxidative activities were evaluated using (1) 2,2-diphenyl-1-picrylhydrazyl (DPPH), (2) 2,2’-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) radical scavenging and (3) ferric reducing antioxidant power (FRAP) methods. Results: All concentrations of herb extracts exhibited higher antioxidant capacities than extract from seedlings. Two antioxidant tests (DPPH, FRAP) showed that full water extract from herb had the highest antioxidant activity, while its non-protein fraction and protein fraction showed lower antioxidant activity. It was found that the full water extract from herb contained the highest concentrations of flavonoids and alkaloids when compared with other samples. Conclusion: Our findings suggest that chelidonine and coptisine especially could be responsible for the observed changes in the extract antioxidant activity, because these alkaloids were determined in the highest concentration in full water extract from herb. It cannot be also excluded that the observed variables values between extracts and their fractions from herb or from seedlings may also be the result of interactions between flavonoids and other chemical compounds.
