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

Figure 1

Percent viability of HepG2 cells treated with DMSO (0.1%) and 100 μg/mL of different fractions of Berberis lycium. Cultures were exposed to treatment for 72 hours, and relative percent viabilities (mean ± SD) were measured using the MTT assay. and significantly different from unexposed cells (Student’s t-test). BLME = Berberis lycium methanolic fraction, BLEA = Berberis lycium ethyl acetate fraction, BLNH = Berberis lycium n-hexane fraction, BLCH = Berberis lycium chloroform fraction, and BLBU = Berberis lycium butanolic fraction.
