Angelica root extract increases the enzymatic activity of alkaline phosphatase in cultured MG-63 cells. (a) The water extracts of Angelica roots at 0.5 mg/mL were applied onto cultured MG-63 cells for 48 hours to determine the enzymatic activity of alkaline phosphatase (ALP). Dexamethasone (50 nM) together with vitamin C (250 μM) was used as a control in MG-63 cells. Values are expressed in percentage of increase as compared with control cultures (without herbal extract) and are in mean ± SD, where n = 4, each with triplicate samples. **P < 0.01. (b) Cultures were treated as in (a) with different DBT at 0.7 mg/mL to determine the enzymatic activity of ALP. Values are expressed in percentage of increase as compared with control cultures (without herbal extract) and are in mean ± SD, where n = 4, each with triplicate samples.
