Unit typinfo contains:
Function IsPublishedProp(Instance: TObject; const PropName: string): Boolean;
Function IsPublishedProp(AClass: TClass; const PropName: string): Boolean;
That should do what you want.

For example, if you want to loop though components and set the
dbNavigator's DataSource property to that of the component if it has a
DataSource property (and of course is not a dbNavigator itself). It
seems you can't do that by using the component's hierarchy. Is there
someway else to do that? Components do seem to have HasHelp and
HasParent properties already.
Something like this:
uses typinfo;
function ComponentHasProperty(aComponent: TComponent; aProperty: string):
boolean;
begin
if not Assigned(aComponent) or (aProperty='') then
Exit(False);
Result:=GetPropInfo(aComponent, aProperty)<>nil;
end;
function ClassHasProperty(aClass: TClass; aProperty: string): boolean;
begin
if (aProperty='') then
Exit(False);
Result:=GetPropInfo(aClass, aProperty)<>nil;
end;
