Antiaging and Antioxidant Bioactivities of Asteraceae Plant Fractions on the Cellular Functions of the Yeast Schizosaccharomyces pombe

Figure 2

Effect of plant extract and fractions on yeast cells viability during stationary phase (chronological aging). Yeast cells were grown in a YES medium containing an optimum concentration of plant extract/fractions as observed previously. Yeast cells grown in EMM medium supplemented with DMSO were designated as calorie restriction for control positive treatment, while yeast cells grown in YES medium supplemented with DMSO only without any extract/fractions addition were used as control. Each culture treatment was then incubated for 7 and 11 days and subjected for spot assay on YES agar. Plates were incubated for three days at 30°C.
