Grape pruning stems constitute a scarcely investigated class of byproducts with limited reports on their bioactive polyphenol content and/or industrial applications. Herein we present the outcome of our investigation on grape pruning stems extracts, concerning the assessment of their total polyphenolic content and the detailed evaluation of their antioxidant properties. Results obtained indicate that grape pruning stems are particularly rich in flavonoids and trans-resveratrol. The antioxidant activities was analyzed and expressed as electron donating ability, ABTS cation radical decolorization, hydrogen peroxide scavenging activity and superoxide anion radical scavenging activity, the antioxidant activity of Vitis labrusca L. pruning stems extracted (GPSE) was higher than that of BHA and L-ascrobic acid. The whitening and anti-wrinkle activities display an capability. Results herein grape pruning stems used as a valuable resource for the extraction of resveratrol, which would be added to functional cosmetics and food materials.
