Lime (Citrus aurantifolia Swingle) is one of the major citrus fruits and widely consumed, but there is limited evidence about its health-promoting properties. Hence, an investigation was conducted to understand the chemopreventive effects of lime juice on pancreatic cancer cells and the possible mechanism for induction of apoptosis using Panc-28 cells. Freeze-dried lime juice was extracted with different solvents, such as chloroform, acetone, MeOH, and MeOH/water (8:2). The chloroform extract showed the highest (85.4 and 90%) radical-scavenging activity by 1,1-diphenyl-2-picryl hydrazyl (DPPH) and 2,2′-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) (ABTS) methods at 624 μg/mL, whereas the MeOH/water extract showed the lowest (<20%) activity. The active components were identified by high-performance liquid chromatography (HPLC) using a C-18 column as rutin, neohesperidin, hesperidin, and …
