dc.description.abstract |
Echinocystis lobata (Michx.) Torr. et A.Gray is a spontaneous species in the Romanian flora, lesser studied by
scientific literature, but which has proved significant activities in traditional medicine. The present study is aimed to provide data on the polyphenolic compounds in the composition of the flowers of this species and to test their biological potential. Polyphenols were identified and quantified using an HPLC-MS method. Tested biological activities were the cytotoxic, anti-plasmodial and antioxidant ones. Methods used for testing the antioxidant activity were the DPPH, CUPRAC, FRAP, TEAC, EPR and SNPAC assays. Cytotoxic activity was tested on cancerous and healthy cell lines and anti-plasmodial activity was assesed on two strains of Plasmodium falciparum. Ethanolic extracts of the flowers of E. lobata proved to contain isoquercitrin, rutin, quercitrin, kaempferol, p-coumaric and ferulic acid. No cytotoxic and antiplasmodial activity was found, but antioxidant assays showed an important antioxidant capacity. The obtained results show that flowers of E. lobata are important sources of antioxidant compounds. It is the first approach of the kind on the flowers of this species and it offers a new perspective on possible sources of antioxidant compounds. |
