[Abstract]Potatoes, one of the world’s four major crops, have been produced in the form of double-cropping. The three potato varieties used in this study were collected from different regions in Japan, namely Kagoshima, Hokkaido and Hiroshima Prefectures, all of which were harvested in spring from the plants planted in the previous winter. Gas chromatography-mass spectrometry (GC-MS) based on solid-phase microextraction (SPME) was employed for analyzing the aroma compositions in essential oil extracted from the peels of each potato varieties. Additionally, evaluation of physiological activities exerted by potato peels was performed using assays to measure their antioxidative and antibacterial activities. The results showed that methoxyphenyl oxime was found in all three varieties, and that particularly this compound was present at 32.47% in the potato peels of Hiroshima variety. Meanwhile, the results from 1,1-diphenyl-2-picryl-hydrazyl (DPPH) radical scavenging assay and active oxygen inhibition assay confirmed that potato peels possessed antioxidative activity. Furthermore, the antibacterial activity of potato peels was exhibited exclusively against Staphylococcus aureus and Pseudomonas aeruginosa, both in a dose dependent manner ranging from 20 to 60μL.
