Immune-enhancing effects of polysaccharides MLN-1 from by-product of Mai-luo-ning in vivo and in vitro

ABSTRACT In this study, a typical Chinese medicine injection (Mai-luo-ning, MLN) was chosen to study the transformation possibility of its by-products (polysaccharides). What’s more, the basic properties of polysaccharides were also detected and its immunoprotect and anti-inflammatory activity were both proved in vivo and in vitro. The experiment determined that MLN-1 significantly increased the level of anti-inflammatory-related factors and the number of lymphocytes. Acute oral toxicity study established that MLN-1 has a non-toxic effect. The present work successfully showed that MLN-1 has the potential to be developed as a food additive
