Abstract

A Maengjong-juk (Phyllostachys pubescence) leaves tea was prepared by using a series of drying/roasting and rolling processes. The produced tea contained abundant dietary fibers (60.42%), $\beta$-carotenes (7.9 mg RE%), and calcium (437.1 mg%). Also the polyphenol content ($155.33\;{\mu}g/g$-tea) and DPPH free radical scavenging activity ($IC_{50}=212\;{\mu}g/mL$) of Maengjong-juk leaves tea were greatly higher than those of simply dried leaves. These results imply that the tea preparation is effective to utilize the useful components of Maengjong-juk leaves.
