Citric plants, specially orange, are of great importance in Brazilian economy, mainly Southeast region. The essential oils from Citrus are one of the most important of raw material group of several industries, mainly for foods, pharmaceutical and toiletry. In foods industry, orange essential oil is utilized to enhance the juice flavor and it is exported, more specific to United States (main consumer). In this work was developed an analytical methodology for identification and quantification of coumarins in citric plants (oils, wax) using chromatographic techniques such as high resolution gas chromatography with flame ionization detector (HRGC-FID) and mass spectrometry detector (HRGC-MS). The results of HRGC-MS qualitative analyses using selective ion monitoring (SIM) indicated the presence of coumarin in the samples of essential oil and wax, and in the latter it was detected the presence of coumarin and psoralen. Quantitative analyses by external standard methods, internal standard and addition of standard showed good results, specially internal standard method which showed greater repeatebility were statistically identical (t test and ANOVA, p = 0.95).
