Sulfated polysaccharides (SPSs) were isolated from 05 mM potassium-sulfate fed Antrodia cinnamomea. We investigated the chemical properties and bio-activities of the five different fractions (SPS-K1, SPS-K2, SPS-K3, SPSK4, and SPS-K5) with molecular weights ranging from 0.51 to 523.48 kDa. SPS-K3 was consisted mainly of glucose, galactose and sulfate in a molar ratio of 15:1:30 with Mn value of 6.82 kDa. It showed maximal inhibition of the tumor necrosis factor (TNF-alpha), interleukin-1beta (IL-1 beta) and interleukin-6 (IL-6) on bacterial LPS-induced inflammation in RAW264.7 macrophage and the production was recorded as 26.19 and 51.06%, respectively. SPS-K2 showed inhibition of endothelial cell tube formation in an in vitro assay of angiogenesis, and IC50 was determined to be 160.92 mu g/ml. Large-scale preparation of SPS was performed in the 3-L fermentation of A. cinnamomea and the yield of the SPS was 5.38%. The area percentage of high-molecular-weight SPSs (1470-1590 kDa) covered almost half of the SPSs mixture characterized by size exclusion column chromatography. The SPSs from fermented A. cinnamomea had significant inhibition on TNF-alpha,1L-1 beta and IL-6 production. This study is the first report to large-scale produce SPSs and demonstrates sulfated galactoglucan with strong anti-inflammatory activity. (C) 2018 Elsevier B.V. All rights reserved.
