A breast cancer study published last year in the Journal of Agriculture and Food Chemistry explored the ability of antioxidant phytochemicals from peaches and plums to reduce breast cancer cell growth in culture. For this study, researchers developed extracts from the Rich Lady peach variety and the Black Splendor plum variety and used them to treat different breast cancer cell lines and healthy, non-cancerous breast cells. The researchers reported:
- The peach extract at a concentration of 42 mg/L inhibited proliferation of estrogen-independent breast cancer cells by 50%.
- A 50% inhibition of cell growth in estrogen-dependent breast cancer cells and non-cancerous breast cells required substantially higher doses.
- The plum extract showed similar, though weaker, results, being more effective against the estrogen-independent breast cancer cells compared to the other breast cancer cells tested.
- Analysis of the antioxidants found in these plum and peach extracts showed that the flavonoids and procyanidins were the most effective, while the phenolic acids and anthocyanins were less effective.
- While the phenolic acids were some of the lesser effective compounds, they still showed a relatively potent cancer fighting effect on estrogen-independent breast cancer cells while having very low toxicity in normal breast cells.
