abstract = "Lycium ruthenicum Murray (Solanaceae), also known as black goji or black wolfberry, has
been used for centuries in traditional medicine and nutrition in Asian countries [1]. In recent
years, black goji berries have been gaining attention as one of the most valuable sources of
anthocyanins with many health-promoting effects [2]. Therefore, this study aimed to
investigate the phytochemical composition and in vitro biological properties of black goji
berry cultivated in southeastern Serbia. The total phenolics, flavonoids, anthocyanins, and
tannins content were determined spectrophotometrically. HPLC-DAD-ESI-MS analysis was
used to identify the phenolic compounds. Methanol extract from black goji berry was
screened for in vitro antioxidant (DPPH∙, ABTS∙+, FRAP, CUPRAC, and β-carotene bleaching
methods), antimicrobial, and hypoglycemic (α-amylase, α-glucosidase) potential.
Phytochemical screening of the extract confirmed the dominant presence of anthocyanins and
hydroxycinnamic acid derivatives, with petunidin 3-p-cumaroylrutinoside-5 glucoside as the
main phenolic compound [3]. The total phenolic content was 18.13 ± 0.15 mg gallic acid
equivalents/g freeze-dried sample. A high correlation is found between the total phenolic
content and the antioxidant activities using different in vitro antioxidant assays. The
antimicrobial activity of the black goji berry extract against eight laboratory control strains
was not pronounced (MIC > 2 mg/ml). The IC50 values were 6.55 ± 0.38 mg/mL and 7.37 ±
0.02 mg/ml for α-amylase, and α-glucosidase inhibition activity, respectively. Overall,
obtained results suggest that the black goji berry cultivated in Serbia should be considered a
valuable source of bioactive compounds for further use in the food, nutraceutical, and
cosmetic industries.",
