We are using hot – water extraction and alcohol extraction and it all depends on the active compounds we want from the mushroom. AQUEOUS or HOT WATER EXTRACTION (teas/decoction): that gives high polysaccharides concentrations but low levels of poorly water – soluble triterpenes. Crude polysaccharide extracts typically have around 30% polysaccharides with further purification possible. ETHANOLIC or ALCOHOL EXTRACTION (tinctures): delivers higher levels of triterpenes but fewer polysaccharides.
