^aWeight-based percentage of soluble polysaccharides in 100 g of lyophilized fruiting body powder of D. indusiata. D1: the 3-fold ethanol precipitate from hot water extracts. D2: the 3-fold ethanol precipitate from 0.04 N HCl extracts. D3: the isoelectric precipitate from 2% NaOH extracts. D4: the 3-fold ethanol precipitate from 2% NaOH extracts. D5: the isoelectric precipitate from 10% KOH extracts; and D6: the 3-fold ethanol precipitate from 10% KOH extracts. Carbohydrate content (% w/w) was measured by the phenol-H₂SO₄ method. Protein content (% w/w) was determined by Bradford protein assay.
^bMean molecular weight.
^cUnanalyzed due to insufficient quantity of sample.
