I'd say, probably type-asserting to a *types.TypeName <https://golang.org/pkg/go/types/#TypeName> and then use Exported() <https://golang.org/pkg/go/types/#TypeName.Exported> (the code of which also leads to ast.IsExported <https://golang.org/pkg/go/ast/#IsExported>).
Side-note: You probably shouldn't rely on parsing the output of String() of any value, just as you shouldn't rely on parsing the output of error.Error().
