実験手順

20 g of the extract prepared in Example 1 was taken in ionized water, sterilized at about 121° C. for 30 minutes, cooled to about 30° C., inoculated with Aspergillus niger KCCM 11885, which had been cultured, in an amount of 5 to 10% based of the total amount of the solution and cultivated at 30° C. for 5 days, preferably 5 days. When icariin completely disappeared by confirming the elimination rate of icariin by thin layer chromatography, the reaction was ended. The resulting culture fluid was centrifuged at 5,000 to 10,000 rpm. The precipitation was washed 3 times with distilled water and centrifuged to obtain precipitation. The precipitation was added to ethanol (200 ml), stirred (3 times) and subjected to filtration to remove residue. The filtrate was concentrated under pressure to obtain a crude product, which was then separated by silica gel column chromatography (chloroform:methanol=8:1 to 4:1) to give 0.8 g of icaritin, 0.7 g of icariside 1 and 0.8 g of icariside II.
