abstract = "In recent years, many preclinical studies have provided evidence that polyphenol compounds
and their metabolites exert prebiotic-like effects by selectively stimulating intestinal bacteria
growth and/or activity [1]. In this study, we investigated the chemical composition,
antioxidant capacity, and prebiotic potential of methanol extracts obtained from Prunus
spinosa L. (blackthorn) and Lycium ruthenicum Murray (black goji) fruits. Polyphenolic
profiles were characterized by using HPLC-DAD-ESI-MS and antioxidant capacity was
estimated with DPPH•, ABTS•+, and FRAP assays. The influence of plant extracts (0.312-5
mg/L) on the growth of three probiotic lactobacilli, probiotic yeast (Saccharomyces
boulardii), and two probiotic mixtures was examined. Studied plant extracts were
characterized by different phenolic compound patterns. Hydroxycinnamic acid derivatives,
quercetin glycosides and anthocyanins were detected in blackthorn extract, while black goji
extract was characterized by the presence of hydroxycinnamic acid derivatives and acylated
anthocyanins. The blackthorn fruit extract showed higher antiradical and reduction activity
than those obtained from black goji fruits. Both extracts have influenced the growth of all
tested probiotics in a concentration-dependent manner, especially of yeast, S. boulardii. The
black goji extract had more stimulatory effects, possibly due to higher anthocyanins content.
When the black goji extract was added to the growth medium at the concentration of 5
mg/mL, about 2-fold stimulation of the growth of S. boulardii was observed. In conclusion,
extracts of the black goji and blackthorn fruits promote the growth of probiotics in vitro.
Further studies are still needed to assess the prebiotic potential of these plant extracts.",
