The column was washed with water and eluted with 95% aqueous methanol. The eluate was concentrated in vacuo to dryness and given the crude powder.
- the portion corresponding to the WF19353D substance was diluted with an equal volume of water and passed through a column (180 ml) of YMC- GEL (ODS-AM 120-S50) packed with water.
- the column was washed with water (540 ml) and 25% aqueous acetonitrile (540 ml) and then eluted with 30% aqueous acetonitrile.
- trifluoroacetic acid was added to the portion corresponding to the WF19353D substance (Final concentration was 0.2%.).
- the solution was diluted with an equal volume of water and passed through a column (38 ml) of YMC-GEL (ODS-AM 120-S50) packed with water.
- the column was washed with water and 25% aqueous methanol containing 0.1% trifluoroacetic acid. Then it was eluted with 40% methanol containing 0.1% trifluoroacetic acid.
- the portion corresponding to the WF19353D substance was diluted with an equal volume of water and passed through a column (5 ml) of YMC GEL (ODS-AM120-S50) packed with water. The column was washed with water and eluted with 95% aqueous methanol. The eluate was concentrated in vacuo to dryness, and given the 4.8 mg of WF19353D substance as a white powder.
