Embodiment Construction

[0017] Utilize 20-95% ethanol to obtain the extract from the coarse powder of Fructus Fructus Fructus by percolation method; the extract is concentrated and put on a macroporous resin column, and eluted with 20-95% ethanol; the eluate is concentrated and put on Silica gel column, eluted with a mixture of chloroform and methanol, concentrated and left to precipitate crude crystals. The crude crystals are repeatedly recrystallized from methanol to obtain white crystals which are neohesperidin.
