Seeing the error in science

Whom would you blame more for these oversights?  The authors?  The journal editors?  The peer reviewers? 



i)                    If values are expressed as means of n =3 plus/minus SD, where are the error bars in any of the graphs? 

 Why encapsulate if extracts themselves have higher polyphenol content than the capsules (Figure 2)?

Are EC50 values in Figure 3 ascorbic acid equivalents?  So higher ascorbic acid equivalents = higher EC50?  But EC50 definition is that lower the concentration to observe certain efficacy, the more potent is that substance.  So how do we interpret Figure 3?
