摘要: Non-communicable diseases (NCDs) present a long duration and slow progression. Good nutrition plays predominant role in NCD prevention. In Chile, the cultivation of strawberry (Fragaria ananassa) has recently been adapted to volcanic soils with low available phosphorus (P), which can affect fruit quality terms their antioxidant compound content anti-inflammatory activities. Here, we carried out study using organic (OF) or chemical (TF) fertilisers at 50 100% agronomical dose recommendation without fertilisation (WF) under field conditions. Identification phenolic compounds was done by HPLC-DAD-ESI-MS/MS, whereas activities were determined spectrophotometric methods. The highest concentrations anthocyanins ascorbic acid obtained OF treatments, showing relationship CUPRAC (cupric reducing capacity) values. total polyphenols TF according TEAC (Trolox equivalent capacity), 2,2-diphenyl-1-picrylhydrazyl tests. enzymatic observed also treatments. Compared WF, treatment downregulates cytokine interleukin 10 (IL-10) significantly 100%, but could not show downregulation yet. Our results suggest that activity responds better period prolonged exposure P fertilisation. There is no direct correlation between non-enzymatic respect treatments different types
