In the present study, small Citrus fruits which are cultivated in our country and have an economic value were chosen as research materials. It was aimed to do fingerprint analysis of the fruits by HPTLC method. DPPH center dot scavenging and antityrosinase potentials were determined in vitro. Extracts showed noticable activities, but these effects were not comparable with positive controls. HPTLC-bioautographic assays and Mass Spectrometry analysis were employed to identify bioactive compound in the extracts. Phloretin-di-C-glucoside was tentatively identified as DPPH center dot scavenging and antityrosinase active compound in kumquat and limequat extracts.
