Contents of carotenoids, phenolic compounds, volatile organic compounds, and alkaloids in leaves, internodes, fruits,and roots of tomatoes in different developmental stages were measured. Lycopene, β-carotene, and lutein were detected in allthe tested parts except roots and green fruits. Lycopene content in red fruits was 49.04 μg･g-1FW, while that in the otherparts was below 40 μg･g-1FW. β-Carotene and lutein contents in 24th leaves were 5.81 and 6.40 μg･g-1FW, respectively, andwere greater than those in the other parts. Caffeic, chlorogenic, and vanillic acids were detected in all the tested parts exceptroots. The content of chlorogenic acid in the 18th leaves was 40.11 μg･g-1FW, while that in the other parts was lower than31.00 μg･g-1FW. The contents of caffeic and vanillic acids in the 24th leaves were 9.18 and 1.64 μg･g-1FW, respectively, andwere greater than those in the other parts. Moreover, younger leaves contained the more diverse volatile organic compoundsincluding monoterpenes and sesquiterpenes. Contents of dehydro-tomatine and -tomatine were greatest in leaves, followed byinternodes, roots and fruits. Younger leaves and internodes contained more dehydro-tomatine and -tomatine than older leavesand internodes. The contents of dehydro-tomatine and -tomatine in the 24th leaves were 0.89 and 1.42 mg･g-1FW, respectively,and were greatest among all the tested parts. Our results indicated that, except lycopene, tomato leaves included greater secondarymetabolites contents than red fruits. The results suggest that inedible parts of tomato plants can be used as raw material forantioxidants, anti-inflammatory agents, fungistats, and pesticides. KCI Citation Count: 8
