This study aimed to explore for the first time the biological properties such as antifungal, antitumoral and antioxidant of Danube Delta Nymphaea alba ( N. alba ) leaf and root methanolic extracts. The toxicity studies of N. alba extracts showed no inhibitory effect on wheat seed germination by evaluating the most sensitive physiological parameters (Germination %, Germination index, Vigor index) and using confocal laser scanning microscopy images. The analyzed extracts were found to have high antifungal activity against Candida glabrata with MIC values of 1.717 µg/mL for leaf and 1.935 µg/mL for root. The antitumor activity of the both extracts against A2780/A2780cisR ovarian, LNCaP prostate and MCF-7 breast cancer cells was promising with IC 50 values ranging from 23-274 µg/mL for leaf and 18-152 µg/mL for root, and the combination of N. alba extracts with cisplatin showed a synergistic effect (coefficient of drug interaction &lt;1). The antioxidant properties were assessed by β-carotene bleaching, ABTS and FRAP assays and cyclic voltammetry. Quercetin, the most prominent antioxidant, was quantified in very good yields by spectroelectrochemical assay.
