- | The ripe fruits are usually harvested after the first frost on the bush. By natural or artificial freezing, a big part of bitter and astringent tannins of the fruit is enzymatically degraded. In this case, the tannin content of the juice decreases from about 1% to less than 0.5%. Complete degradation of tannins is not intended because of their significant contribute to flavor. \\ | + | | {{: |

"In the 5-lipoxygenase test the fresh fruit juice of P.spinosa showed a good antioxidant activity when compared to trolox; in the DPPH test the samples showed IC50 values that were comparable to ascorbic acid, while the ORAC value was 36.02 μmol eq. trolox/g of fruit. These values are in accord with data reported in the literature for small fruits such as vaccinium, rubus and ribes. the antioxidant activity of red berries is correlated with the anthocyanin content. the results of this study indicate that the three most | "In the 5-lipoxygenase test the fresh fruit juice of P.spinosa showed a good antioxidant activity when compared to trolox; in the DPPH test the samples showed IC50 values that were comparable to ascorbic acid, while the ORAC value was 36.02 μmol eq. trolox/g of fruit.

- | "P. spinosa fruits are sometimes eaten raw, and commonly prepared in jams or macerated with sugar, honey and brandy to obtain a digestive and laxative liqueur... P. spinosa fruits presented the highest concentration in phenolic acids (29.78 mg/100 g dw), being 3-O-caffeoylquinic acid the most abundant one, and flavone/ols (57.48 mg/100 g), among which quercetin-3-O-rutinoside (15.63 mg/100g) was the major compound." | + | " |
