: Enzymes such as tyrosinase, hyalurodinase etc. contribute to the skin whitening activity of the
plants. Tyrosinase inhibition activity is the main factor that determines the skin whitening activity of the plant
extracts. Owing to the presence of pharmaceutically significant secondary metabolites in Eichhornia crassipes
(Mart.) Solms, the ethyl acetate extract was formulated into a cream with ethyl acetate extract, lemon and musk
and tested for its skin whitening efficiency by in vitro tyrosinase assay. The results of the study revealed 8 to
11% tyrosinase inhibition even at lower concentrations. The plant extract can be formulated into creams with
other active ingredients and can be used in cosmeceutical industry.
