This work is to optimize extraction processing from Haesongi mushroom (Hypsizigus marmoreus) using response surface methodology, and to compare physiological properties of separated fractions from the extracts. Central composite design was adopted in extraction processing optimization. Extraction temperature (X1), extraction time (X2), and Volume ratio of solvent (X3) were chosen for independent variables. Dependant variables were extraction yield (Y1), phenolic compound contents (Y2), and beta glucan contents (Y3). Optimal conditions were X1 = 71.57℃, X2 = 11.31 (hrs), and X3 = 51.58, and predicted values of multiple response optimal conditions were Y1 = 57.00 (%), Y2 = 1.80 (%), and Y3 = 22.00 (%). The extract (SE) was treated with ethanol and the supernatant were cut off with dialysis tubing. The cut off sample (COE) was separated with anion exchange column to AP and NP.
In order to investigate physiological properties of the each fractions, contents of phenolic compounds, beta-glucan, monosaccharides composition, DPPH radical scavenging abilities, ACE inhibitory activities, alpha-amylase, glucosidase inhibitory activities, cytotoxicity, and adiopogenesis were measured.
Beta glucan contents of COE were the highest and phenolic compound contents of SE were the highest, significantly. SE was most effective on antioxidant properties. COE show the highest properties at antidiabetic and antiobesity. Moreover COE had the highest cytotoxicity on HepG2 cell. NP shown the highest cytotoxicity effect on AGS cell and AP had the highest antihypertension effects. However, cytotoxicities of all fractions were shown low effect on SW480.
The major monosaccharides of COE were glucose, galactose, mannose, and fucose, of AP were glucose and galactose, and of NP were galactose, mannose, and fucose.
