ABSTRACT

Objective:

In this study, ultrafiltration membrane process is employed first to separate the polysaccharides from industrialization waste in Mailuoning Injection and to promote the resources utilization of the waste.

Methods:

The waste ethanol sediments in the production of Mailuoning Injection mainly include dendrobium polysaccharides, Achyranthes bidentata polysaccharides (ABPS), and honeysuckle polysaccharides, and the active components of polysaccharide with high content were selected through the immune activity. Six different relative molecular weight cut-off membranes ( 3 × 105) made of polyether sulfone (PES) were used. Six fractions were obtained and named as MFP1, MFP2, MFP3, MFP4, MFP5, and MFP6. Meanwhile, polysaccharides and protein content were determined by phenol-sulfuric acid colorimetry and Coomassie brilliant blue G-250 staining method; Polysaccharides species was analyzed by ELSD-HPLC; Immunocompetence of different fractions were investigated in vitro, including mouse spleen lymphocytes proliferation, transformation, and production of nitric oxide after acting on the macrophage RAW264.7.

Results:

The results showed MFP4 (3 × 104-1 × 105) have the highest content and immunocompetent, MFP5 (1 × 105-3 × 105) immunocompetent followed, compared to others, purity, and recovery of MFP4 are 76.80% and 10.81%, purity and recovery of MFP5 are 73.23% and 14.73%, respectively.

Conclusion:

The findings reveal MFP4 and MFP5 serves as our object of exploitation in the future; Moreover, separation of polysaccharides from "Mailuoning Injection" by the membrane is feasible with high recovery and low cost in the realization of circular economy.
