Nelumbo nucifera extracts as whitening and anti-wrinkle cosmetic agent

摘要

Water extract from Nelumbo nucifera was tested for possible functional cosmetic agent. Whitening effect was measured by tyrosinase inhibition assay and DOPA-oxidase inhibition assay, and anti-wrinkle effect was checked by elastase inhibition assay. DOPA-oxidase inhibition effect (whitening effect) of Nelumbo nucifera's leaf, seed and flower extract was 59%, 57% and 50%, respectively. Nelumbo nucifera's leaf, seed and flower extract showed 56%, 49%, and 54% elastase inhibition (anti-wrinkle effect) at 200 ug/ml, while adenosine indicated 26% inhibition. Water cream including Nelumbo nucifera's root, leaf, flower, stem extract did not cause significant skin irritation. Water cream including 4% Nelumbo nucifera extract was stable for 30 days under various temperature conditions. From the study, Nelumbo nucifera's leaf, flower and seed extracts showed strong possibility for whitening and anti-wrinkle functional cosmetic agent.
