Beauty food activities of extracts from Pinus densiflora root

The extracted phenolic compounds from Pinus densiflora root were examined biological activities for beauty food. The tyrosinase inhibitory activity which was related to skin-whitening was observed. The tyrosinase inhibitory activity was confirmed to be 92% in ethanol extract at 50 µg/mL phenolic. The elastase and collagenase inhibitory activity as anti-wrinkle effect were showed 61 and 78% in ethanol extract at 200 µg/mL phenolic, respectively. Astringent effect of ethanol extract was showed to be 82% at 50 µg/mL phenolic. Hyaluronidase inhibitory activity of ethanol extract as anti-inflammation effect was confirmed to be 94% of inhibition at 200 µg/mL phenolic. These results demonstrated that isolated phenolic compounds from P. densiflora root could be expected to use as a functional cosmetic materials.
