Abstract Breast cancer is the most common type of cancer and has the highest mortality rate in women.Most of the methods used in cancer therapy have significant side effects. In recent years, the use of medicinal plants and products derived from them to prevent, treat and also manage the side effects of cancer has been considered. Pomegranates include a variety of phytochemical and phenolic substances. This study was aimed to investigate the impact of pomegranate flower ethanolic extract on breast cancer cells (human breast cancer cell line). Initially, ethanolic extracts of P. granatum flowers were extracted from its dried powders. Using the 3-(4, 5 dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide test, the cytotoxic effects of the ethanolic extract of pomegranate flowers were evaluated in human breast cancer cell line compared with normal mouse fibroblast cells. According to our findings, Punica granatum ethanolic extracts are less toxic to normal cells compared to human breast cancer cell line. Consequently, the minimum and maximum lethal concentrations of the P. granatum flower in normal cells were identified to be 150 and 450 μg/ml, whereas the minimum and maximum lethal concentrations were determined to be 700 and 1000 μg/ml in human breast cancer cell line. The present study showed that pomegranate flower has anti-breast cancer potential. This potential benefit can be further examined in future research.

"Carotenoids Content in Plant Organs of Taraxacum Officinale (L.) Species from Two Romanian Regions"

"Carotenoids are pigments that occur naturally in bacteria, algae, fungi and plants and give them their orange or red colour. The most important carotenoids that have beneficial effects on human health are beta-carotene, lutein, astaxanthin, lycopene and zeaxanthin. The main advantage of carotenoids lies in their antioxidant potential, the role of protecting the body's cells from damage by unstable oxygen molecules. The present paper presents the comparative content of carotenoid-type bioactive compounds present in the hydroalcoholic extracts obtained from different plant organs (roots, leaves and flowers) of the species Taraxacum officinale (L.), dandelion. The plant product was collected from the spontaneous flora, the southern area of Dobrogea, Constanța county and from the eastern area of Transylvania, Harghita county, in May 2022. The obtained hydroalcoholic extracts of 10% concentration in 50% ethanol and respectively 70% ethanol, using the cold maceration method, in the dark, for 14 days, were analysed by UV-Vis spectrophotometry to determine the total content of carotenoids, beta-carotene and lutein. Total carotenoids content was higher in ethanolic extracts of roots and flowers of plants collected from the southern area of Dobrogea, and for the leaves the content of total carotenoids was higher in the ethanolic extracts of the plants collected from the eastern area of Transylvania. The differential distribution observed in terms of the carotenoids content present in the various plant organs of the species Taraxacum officinale (L.), may be due to the influence of the climate and the type of soil characteristic of the two studied areas. Enriching the database regarding the concentration of analysed carotenoid-type bioactive principles can contribute to the development and testing of hypotheses about the therapeutic potential of this valuable component of the Romanian spontaneous flora."
