Figure 4: Control Charts showing the evaluated characteristics of the extracts within the confidence limits on the maceration process:(a) Extraction yield (%); (b) ursolic acid and (c) oleanolic acid contents determined by HPLC-DAD; (d) total phenol content by Folin-Ciocalteau test. Control limits with 99% (solid) and 95% (dashed) confidence are indicated (see Table 3)
