Oxygen Radical Absorbance Capacity (ORAC), Anthocyanin, and Ellagic Acid Values
The ORAC value of selected U.S. Northwest blackberries is in the range of 24-77 umole/g fruit. Anthocyanin content is in the range of 100-600 mg/100g fruit, and Ellagic Acid in the range of 3.4-6.0 mg/100 g fruit. For more detailed value for specific berries, please view the materials at the Oregon Raspberry & Blackberry Commission website.
- The ORACfl (umoleTE/g) analysis, which utilizes Fluorescein as the fluorescent probe, provides a measure of the scavenging capacity of antioxidants against the peroxyl radical, which is one of the most common reactive oxygen species (ROS) found in the body.
- Trolox, a water-soluable Vitamin E analog, is used as the calibration standard and the ORAC result is expressed as micromole Trolox equivalent (TE) per gram.
Other Nutraceutical Values of Blackberries
|Anthocyanins||109-155 mg/100g||83-326 mg/100g||120-160 mg/100g|
|Ellagic Acid||5.83 mg/g dry wt||3.69 mg/g dry wt||5.98 mg/g dry wt|
|ORAC||28 umole TE/g||28 umole TE/g||42 umole TE/g|
|Gallic Acid||3 mg/100 mg||2 mg/100 mg||9 mg/100g|

Marionberries, Boysenberries, Loganberries and other blackberries are high in gallic acid, rutin and ellagic acid, a known chemopreventative, with anti-viral and anti-bacterial properties. With their dark blue color, blackberries have one of the highest antioxidant levels of fruits regularly tested. Blackberries are also rich in Vitamin C and fiber, which have been shown to help reduce the risks of certain cancers. Blackberries are low in calories, carbohydrates and have no fat, which makes them popular in low carb and low calorie diets.
- High in Vitamin C and fiber both of which have been shown to help reduce the risks
of certain cancers.
- Contains high levels of anthocyanins (83-326 mg/ 100g) which work as antioxidants to help fight free radical damage in the body and give berries their deep dark color.
- The antioxidant level of foods can be measured as ORAC (Oxygen Radical
Absorption Capacity). The ORAC value of Evergreen blackberries is 28
µmoles/TE/g, slightly higher than blueberries.
- Evergreen blackberries contain ellagic acid, a phenolic compound shown to have
anti-carcinogen, anti-viral and anti-bacterial properties. The ellagic acid levels of
Evergreen blackberries is 3.69 mg/g of dry weight.
