| Abstract: | "An analytical procedure based on in-tube extraction followed by gas chromatography with mass spectrometry has been developed for the analysis of 24 of the main volatile components in cape gooseberry (Physalis peruviana L.) samples. According to their chemical structure, the compounds were organized into different groups: one hydrocarbon, one aldehyde, four alcohols, four esters, and 14 monoterpenes. By single-factor experiments, incubation temperature, incubation time, extraction volume, extraction strokes, extraction speed, desorption temperature, and desorption speed were determined as 60 degrees C, 20 min, 1000 muL, 20, 50:50 muL/s, 280 degrees C, 100 muL/s, respectively. Quantitative analysis using authentic standards and external calibration curves was performed. The limit of detection and limit of quantification for the analytical procedure were calculated. Results shown the benzaldehyde, ethyl butanoate, 2-methyl-1-butanol, 1-hexanol, 1-butanol, alpha-terpineol, and terpinen-4-ol were the most abundant volatile compounds in analyzed fruits (68.6-585 mug/kg). The obtained data may contribute to qualify cape gooseberry to the group of superfruits and, therefore, increase its popularity" |
