Background. Carotenoids have played a significant role in reducing the risk of chronic disease. The most studied in this regard is β-carotene, present in medicinal plants specific including Calendula and Tagetes genus. Objective of the study. Comparative analysis of β-carotene content in liquid and dry extracts obtained fromflowers of species Tagetes and Calendula, cultivated in the colection of the Scientific Center for the Cultivation of Medicinal Plants of Nicolae Testemitanu SUMPh. Material and Methods. Liquid extracts obtained by repeated maceration, dry extracts, by rotary evaporation, were subjected to phytochemical evaluation by thin layer chromatography (TLC) and UVVIS spectrophotometry, equivalent to β-carotene. Results. Beta-carotene was identified by TLC in hexane- ethyl acetate (50:50, v/v), retention times were established. Caratenoid content (mg %) varied as follows: in T. patula (75.34), T. erecta (21.97), C. officinalis variety Natali (13.09), C. officinalis variety Diana (12.39), C. officinalis local population (10.99). The carotenoids varied in dry extracts too, determined in highest amount in T. patula flowers (137.87 mg%). Conclusion. This study demonstrated the opportunity for further research of Tagetes varieties that could serve as sources of carotenoids for antioxidant phyto-pharmaceuticals |
