The Inhibitory Effects on Cytotoxicity and Nitric Oxide (NO) of the Nano-Encapsulated Extraction of Lipid-Soluble Green Tea Leaves.

The purpose of this study was to investigate the bioactive substances and extraction conditions of lipid-soluble green tee extract using supercritical CO extraction from green tea leaves growing in Boseong-gun, Jeollanam-do and to demonstrate cell safety and effects on inflammatory response of the nano-encapsulated lipid-soluble green tee extract. The polyphenol content of green tea extract using supercritical CO₂ extraction was analyzed. The highest polyphenol was extracted in the condition of 400 bar/50 °C.
