In this study, we investigated the variation in free sugars, organic acids, antioxidant activity and anti-inflammatory effect of Solanum nigrum Linne fruits according to harvest time. Four kinds of free sugars (fructose, glucose, sucrose, maltose) were detected in S. nigrum fruit, and the free sugar contents varied significantly with harvest time. Organic acid content of S. nigrum fruit showed the highest in malic acid and acetic acid, and the highest content of total organic acids was found in S. nigrum fruit harvested on October 18 th and October 25 th. For the total polyphenol content, S. nigrum fruit harvested on October 18 th was the highest. The strongest DPPH and ABTS radical scavenging activity was showed in S. nigrum fruit harvested on October 11 th and October 18 th. The anti-inflammatory activity and antioxidant effects were the highest in the ethanol extract from S. nigrum fruit collected on October 18 th and October 11 th. Thus, it seems the best to harvest of S. nigrum fruit harvested on October 11 th and October 18 th.

This chapter focuses on the chemical composition (phenolic compounds and flavonoids), antioxidant activity and human cell line cytotoxicity of 47 Korean edible wild plants. Correlations among the various antioxidant substances and activities of the methanolic extracts of the 47 wild edible and medicinal plants are also discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
