Study on Biological Activities of Extracts for Cosmeceutical Development from Lagerstroemia indica L. Branch

Abstract- The aim of the study was to examine the cosmetic and biological activity of Lagerstroemia indica L. and it is possible that can be used as a cosmetic ingredient for application of cosmetic industries. Lagerstroemia indica L. branch was extracted with 70 % acetone in water. In the result of DPPH (1,1-diphenyl-2-picryl-hydrazyl) scavenging radical activity, acetone extract of Lagerstroemia indica L. branch were higher than 73 % at the 50 ppm concentration. ABTS radical cation decolorization activity by acetone extract were higher than 78 % at the 50 ppm. Both examine of DPPH and ABTS showed high antioxidative activities at the 50 ppm. In the result of nitrite scavenging ability, acetone extract were higher than 63% at the 50 ppm. Collagenase inhibition activity by extract were higher than 85 % at the 50 ppm. Extract is showed high collagenase inhibition more than comparison group EGCG at all concentration. These results suggest that Lagerstroemia indica L. has a great potential as a cosmeceutical raw material as well as anti-oxidant and anti-inflammatory and collagenase inhibition activity.
