  • Lycii Fructus (LF) has been reported to possess various biological activities. In this study, we investigated the anti-inflammatory and anti-allergic effects of LF extract in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophage cells and rat peritoneal mast cells(RPMC). LF extract inhibited NO production and the expressions of inducible NO synthase (iNOS) mRNA and enzyme protein, determined by Griess reactions, RT-PCR and Western blotting, respectively, in LPS-stimulated RAW 264.7 macrophages cells. LF extract significantly inhibited histamine release in compound48/80 stimulated rat peritoneal mast cells compared with the compound48/80 only treated cells. It is suggested that the LF extract can improve the inflammation status that involves the histamine release.

  • Quality and shelf life of the wet noodle made with 1, 3, 5, and 7% (w/w%) Lycii fructus powder were investigated. Increase in L. fructus power concentration increased the initial pasting temperature and cooking loss, while maximum viscosity, temperature at maximum viscosity, weights and volumes of cooking noodles, and textural properties (hardness, cohesiveness, chewiness, springiness) of cooked noodle prepared with composite flour decreased. The sensory evaluation of cooked noodles showed that wet noodles with high quality could be produced by 3% inclusion of L. fructus powder. Bacterial counts of wet noodles made with L. fructus powder were lower than those of the control after storage at $5{\pm}1^{\circ}C$. Shelf life of wet noodles during storage at $5{\pm}1^{\circ}C$ extended as the L. fructus powder concentration increased.
