Antioxidant Phytocomplexes Extracted from Pomegranate (Punica granatum L.) Using Hydrodynamic Cavitation Show Potential Anticancer Activity In Vitro

What if a pomegranate could fight cancer without harming healthy cells? A new study shows that a simple water-based extraction technique can unlock this potential in just 15 minutes.

Pomegranates have long been celebrated for their health benefits, but their anticancer secrets are locked inside complex phytochemicals. Now, scientists have found a fast, scalable way to release them: hydrodynamic cavitation. This technique uses the power of collapsing bubbles in water to break plant cells, releasing valuable antioxidants without harsh solvents.

In a first-of-its-kind study, whole pomegranate fruits were extracted in water using hydrodynamic cavitation. The resulting fractions, labeled M1 to M5, were processed in three ways: lyophilized, filtered, or left crude. Among these, the M3 and M4 fractions from the lyophilized and crude series showed the highest antiradical activity and phytochemical content.

The most promising sample, L-M3, was produced in just 15 minutes at room temperature (30°C) with lower energy consumption than M4. When tested on human breast cancer cells (AU565-PAR), L-M3 significantly reduced tumor cell proliferation and intracellular reactive oxygen species. Remarkably, it had no effect on healthy peripheral blood mononuclear cells (PBMCs) from donors.

This pilot study suggests that hydrodynamic cavitation can produce antioxidant phytocomplexes from pomegranate that are not only efficient but also selectively toxic to cancer cells. While more research is needed, this green extraction method could pave the way for affordable, natural anticancer therapies.

Key Points

• Hydrodynamic cavitation extracts antioxidants from whole pomegranate in water.
• L-M3 fraction halts breast cancer cell growth and reduces reactive oxygen species.
• No effect on healthy donor cells; production at 30°C in 15 minutes.
