Anthocyanins in Black Raspberries Have Anticancer Properties
The Cancer Prevention Research Journal report that anthocyanins from black raspberries have anticancer properties. Anthocyanins are flavonoid compounds that are responsible for dark (blue, purple, red) pigments in the flowers, leaves, stems roots and fruits of plants.
The research was carried out at Ohio State Comprehensive Cancer Centre. Rats with esophageal cancer were fed whole black raspberries and the fruit extracts containing high amounts of anthocyanins. It was discovered that anthocyanins can inhibit the growth of cancer cells as well as make the cancer cells commit suicide. The results showed that both the whole raspberry fruits and the anthocyanin rich extract were effective in preventing esophageal cancer in rats Trials were also conducted using whole berry powder. The results were also promising, however patients needed to take up to 60 grams of powder per day
“Now that we know the anthocyanins in berries are almost as active as whole berries themselves, we hope to be able to prevent cancer in humans using a standardized mixture of anthocyanins. The goal is to potentially replace whole berry powder with its active components and then figure out better ways to deliver these components to tissues, to increase their uptake and effectiveness. Ultimately, we hope to test the anthocyanins for effectiveness in multiple organ sites in humans,” said Dr Gary Stoner. Black raspberries belong to the rose family, genus Rubus. Two species, R. leucodermis and R. occidentalis are commonly known as black raspberries. They are said to be one of the richest berries with regard to anthocyanin content. Previous studies have already indicated the potential of black raspberries in cancer therapy. A 2006 trial reported positive effects in patients with Barrett’s esophagus, a pre-malignant for of esophageal cancer.
