Anthocyanins in NatureAnthocyanins are being used in organic solar cells because of their ability to absorb light and convert it into electrons.

Work on laboratory cancer models has shown that black raspberry anthocyanins inhibit promotion and progression of tumor cells by ….1. stalling growth of pre-malignant cells2. accelerating the rate of cell turnover, called apoptosis, effectively making the cancer cells die faster3. reducing inflammatory mediators that initiate tumor onset4. inhibiting growth of new blood vessels that nourish tumors, a process called angiogenesis5. minimizing cancer-induced DNA damage.
