Is it possible to get the value of a GUID on an interface using RTTI?

Question

If I have an interface such as:

IPluginAPI = interface
['{590DFF0B-CA00-46CC-84B0-3848103D4C5A}']
   function add (a : double; b : double) : double;
   function sub (a : double; b : double) : double;
   function mult (a : double; b : double) : double;
   function divide (a : double; b : double) : double;
end;

Is there anyway to get the value of the GUID using RTTI? I am using Delphi XE.

uses
  TypInfo;

Guid := GetTypeData(TypeInfo(IPluginAPI))^.Guid;
