The purpose of this study was to perform qualitative and quantitative analysis of a hydroquinone content in a night cream from all beauty clinics at Jl. Margonda Raya Depok. 4 (four) product for test materials obtained randomly from 10 existing clinics, and analyzed using high-performance liquid chromatography. With reference to the requirements set forth by the National Food and Drug Agency through Head of National Food and Drug Agency Regulation No:  HK. 03.1.23.08.11.07517 in 2011 about technical requirements for Cosmetic Ingredients, Hydroquinone is not allowed occur on the product for the skin or hair so the cream products A, B and D declared ineligible whereas C cream product is qualified.

A high-performance liquid chromatography method was developed and validated for the quantification of the cytotoxic compounds produced by a marine strain ofAspergillus niger. The fungus was grown in malt peptone dextrose (MPD), potato dextrose yeast (PDY), and mannitol peptone yeast (MnPY) media during 7, 14, 21, and 28 days, and the natural products were identified by standard compounds. The validation parameters obtained were selectivity, linearity (coefficient of correlation > 0.99), precision (relative standard deviation below 5%), and accuracy (recovery > 96).
