BuddyPress.org

I have non wordpress installed in sub-domain..The main domain is wordpress with bp installed.. They are sharing the same database with login users and other credentials.. Now what I want is to show some of the values of xprofile fields of main wp domain in to the sub domain (non wp) site..Like for example ‘about’ field..

I could have done through ‘SELECT’ in the database query using $_session but I see there are no values of xprofile fields are stored in the db.. Am i missing something that it stores value in db? If they are not stored in db, is there any other alternative to achieve my goal..?

Thanks
