Investigating the Antiproliferative and Antioxidant Properties of Pancratium maritimum L. (Amaryllidaceae) Stems, Flowers, Bulbs, and Fruits Extracts

Pancratium maritimum stems, flowers, bulbs, and fruits extracts were investigated for their antiproliferative and antioxidant properties. Total phenols and total flavonoids were also determined. The in vitro antiproliferative activity was tested against seven cancer cell lines such as C32, HeLa, MDA-MB-231, PC3, A549, MCF-7, and LNCaP by using SRB assay. Interesting results were obtained with stems ethanol extract (ET1) against C32 cells (IC(50) of 27.1 μg/mL) and fruits aqueous extract (AQ) against MCF-7 cell line (IC(50) of 36.5 μg/mL). To define the antioxidant activity, four tests such as DPPH, ABTS FRAP, and β-carotene bleaching tests were used. The most promising ABTS scavenging capacity was observed with fruits ethanol extract (ET1) that showed an IC(50) value of 6.9 μg/mL. According to the correlation results, the phenols and flavonoids content could provide a fundamental contribution to the antioxidant and antiproliferative activity of P. maritimum extracts.
