You need to load this field in TRichView/TDBRichView component and then save as text.
For loading, you can either link TDBRichView to this field, or use TRichView.LoadRVFFromStream (see Demos\*\DB Demo\2 RichViewEdit)

For saving, you can, for example, use GetAllText from RVGetText unit (or from RVGetTextW unit, if you need Unicode text).

If you download a trial version, it includes RVGetTextW.dcu.
