Effect of polyphenol-rich plant extracts on preadipocyte viability. Cells were exposed to each plant extract (25 μM GAE) for 24 and 48 h. (a) In order to assess cell growth, cells were counted manually by using Trypan blue reagent. (b) To evaluate cell death, LDH activity in the cell culture medium was determined by using an enzymatic kit. Data are means ± SEM of three independent experiments.
