Abstract:
1. A polysaceharide extracted from Antrodia camphorata by (1) using CHCl 3 to extract freeze-dried power of Antrodia Camphorata , (2) dipping the residue into 100° C. water to extract, (3) adding EtOH to the extract, (4) stirring the mixture and put it into a refrigerator for one night, (5) filtering and washing precipitate with cold EtOH, (6) treating precipitate with 10% trichloroacetic acid (TCA), (7) dialyzing the TCA-soluble fraction obtained by centrifugation against distilled water, and (8) lyophilizing the nondialyzed portion, wherein the polysaccharide has characteristics as follows: (a) appearance: colorless and shapeless powder, (b) pH: neutral, (c) molecular weight: 1285 kDa determined by HPLC as shown in (d) rotatory power: [α] (e) intrinsic viscosity: [η]=0.0417 dl·g (f) specific heat Cp: 0.2663 Cal/g·° C., (g) IR spectrum: as shown in (h) (i) (j) GC-MS analysis: as shown in
