anthocyanin comparison

Our USDA-certified organic Ukrainian elderberries tested at 8.45 mg/g total anthocyanins, compared to 2.11 mg/g in a sample of American-grown elderberries.
That's approximately 4 times higher anthocyanin content.
All testing was performed by an independent ISO/IEC 17025 accredited laboratory using the same analytical method for both samples.
