Black elderberry has a long tradition of use for immune support. The berries are high in flavonoids, predominantly anthocyanins, but also quercetin and rutin. Anthocyanins impart the characteristic purple color to the berries, as well as much of the bio-efficacy in terms of antioxidant activity, balancing inflammation metabolism, and supporting immune function.
Today’s PLT elderberry portfolio includes extracts standardized to 6% and 10% anthocyanins, offered in both standard and organic grades in a powder form. Quality for these ingredients is assured by a per-batch testing program including fingerprint analysis for identification and quantification of anthocyanins, DNA sequential barcoding for authenticity, analysis for adulteration using the MALDI TOF technique, and standardization of biomarkers.
