extract was then centrifuged at 5000 rpm/min. Supernatant were evaporated to dryness under reduced pressure (35 to 40 °C). The residue was dissolved in 25 mL of water/ethanol (80:20, v/v) and extracted four times with 25 mL of ethyl acetate. The organic

samples of 0.2 g were cut and mixed, and 5 mL of deionized water was added to extract the soluble sugar in a boiling water bath for 30 min (repeated twice). Anthrone ethyl acetate reagent (0.5 mL) and concentrated sulfuric acid (5 mL) were added to 0.5 mL
