Comparisons between Hydro and Steam Distillation Processes to Extract Prunella Vulgaris Volatile Compounds, and their Anti-oxidative Activities

Objective The aim is to verify our earlier suggestion which accounted for the dynamics of volatile compounds extraction from herb Prunella vulgaris (PV) using steam distillation. Then, anti-oxidative property PV explored.
 Methods Because we suggested that inefficient distillation was due obstruction a mass in flow path, used hydro tried eliminate this obstacle. We GC-MS characterize extracted, and thus compare efficiency. treating cancer cells SCC154 cell-line with distillate, cell cytotoxicity assessed colorimetric test reagent, Cell Counting Kit-8. To assess activity Folin-Ciocalteu reagent used.
 Results successfully showed removal obstacle, formed by enhanced efficiency compound extraction. Also, distillate did not exhibit activity.
 Conclusions Hydro more efficient method than extract herb. However, mild heating provide sufficient energy convection boiling water move floating herb; obstacle still existed limited also. For another issue antioxidant effect PV, it studied reagent. It possess property.
