Isolation of Oxyberberine and β-Sitosterol from Berberis lycium Royle Root Bark Extract and In Vitro Cytotoxicity against Liver and Lung Cancer Cell Lines.

Isolation of Oxyberberine and β-Sitosterol from Berberis lycium Royle Root Bark Extract and In Vitro Cytotoxicity against Liver and Lung Cancer Cell Lines. Evid Based Complement Alternat Med. 2020;2020:2596082 Authors: Anwar MA, Tabassam S, Gulfraz M, Sheeraz Ahmad M, Raja GK, Arshad M Abstract Berberis lycium Royle has been traditionally used to cure rheumatism, eye and ear diseases, malarial fever, diabetes, stomach disorders, and skin diseases. There is a least amount of data available on cytotoxic capacity of Berberis lycium from Pakistani origin, so on this basis, the present study was aimed to screen Berberis lycium root bark extracts for cytotoxicity against cancer cell lines and isolation of chemical constituents from the most cytotoxic extract. Initial screening of extracts was performed on HepG2 cells at 100 μg/mL for 72 hours of treatment by using an MTT assay. Active fractions were subjected to a series of column chromatographies for the isolation of cytotoxic compounds. Molecular structures were elucidated by using combined data from 1H-NMR, 13C-NMR, and ESI-MS graphs. Assessment of reduction in cell proliferation by isolated compounds was performed on three human cancer cell lines (SK-Hep-1, HepG2, and NCI-H1299). Both n-hexane and chloroform fractions were found active with percent cell viabilities of 8.41 ± 2.23 and 22.31 ± 9.11 in HepG2 cells compared with lupeol 35.43 ± 3.35 percent viability. A p...
