Bamboo stems extract containing porous silica has been used for medicine, food, paper and craft industry. Bamboo silica is known to support absorbing essential minerals such as calcium, potassium, and magnesium in skin, nail and hair. In this study, extract of domestic bamboos containing silica from two species of Phyllostachys nigra var. Enonis Stapf. and Phyllostachys bambusoides was prepared to prepare the bamboo silica materials. Physicochemical properties have been determined with XRD, FT-IR, FE-SEM and EDX. In addition, enzyme inhibition assay of collagenase and elastase has been performed. Phyllostachys nigra var. Enonis Stapf. silica (PNS) and Phyllostachys bambusoides silica (PBS) inhibited collagenase with IC50 value of 174.14 μg/mL and 292.60 μg/mL, respectively. While, positive control groups of retinol and α-tocopherol were shown to be IC50 values of 49.43 μg/mL and 63.70 μg/mL, respectively. Furthermore, PNS and PBS elastase inhibition rate was 179.46 μg/mL and 377.03 μg/mL. These results suggest that PNS and PBS could be used as a candidate for anti-wrinkle new cosmetic ingredients.
