Maqui Berry Clinical Studies

Study #1


"The average total anthocyanin content was 137.6 ± 0.4 mg/100 g of fresh fruit (211.9 ± 0.6 mg/100 g dry weight), which is similar to those concentrations found in other berries considered to be good sources of anthocyanins (Mazza and Miniati, 1993; Clifford, 2000). A prominent feature of the anthocyanin composition of Maqui is that its biosynthetic pathway is largely channelled towards the formation of polyglycosylated derivatives that are highly polar and water-soluble."

Study #2


"Antioxidant activities of MeOH extract were strongly correlated with total polyphenol content. Consistent with this finding, MeOH had the greatest ORAC and FRAP values as percentage of activity. These results show that these fruits could be useful as antioxidant, cardioprotective and nutraceutical sources."

Study #3


"Antioxidant capacity, measured as oxygen radical scavenging capacity and expressed as Trolox equivalents, was higher in the berries of A. chilensis. Phenolic extracts inhibited lipid accumulation by 4.0-10.8% when adipocytes were treated at maturity and by 5.9-37.9% when treated throughout differentiation."
