The FRGE used in our previous study, which was
extracted for 8 h at 70C with water, failed to reduce LPS-induced
NO production (Park et al., 2012). The isolation procedure
used for FRGE in our previous study is different from that used
for FRGE in this study in the view of extraction temperature
and time. Rather, the isolation procedure is similar to that used
for HRGE in this study as application of heat.
