Lentinan, 1152 Dalton β-D-glucan found in Shiitake Mushroom (Lentinus edodes), has been claimed to have anticancer and immunomodulatory activity. Several extraction methods have been used by researchers to isolate Lentinan including hot water and alkaline solution (1.25 M NaOH). In this study, hot water and alkaline solution (1.25 M NaOH) were used to extract the Lentinan-like β-D-glucan (1151 Dalton) from Tiger’s Milk Mushroom, Termite Mushroom, and selected local market mushrooms. The isolated Lentinan-like β-D-glucan from both hot water and alkaline solution was analyzed by LCMS-QTOF. Commercial Lentinan standard from Lentinus edodes was used as a reference. The results showed significant differences on chromatogram patterns of Lentinan-like β-D-glucan between both extracts. The peak of Lentinan-like β-D-glucan was only found in isolated polysaccharide glucan of hot water extracts. The isolated polysaccharide glucans from Tiger’s Milk Mushroom and Termite Mushroom were found to have μg/mg and μg/mg Lentinan-like β-D-glucan. Button Mushroom, Shiitake Mushroom, and Oyster Mushroom showed the presence of Lentinan-like β-D-glucan at μg/mg, , and μg/mg, respectively.
