Find custom content from page manager in MyPHP Admin

When I create a new page, i can add content to the different regions i defined. I can choose custom blocks, menus, mini panels, miscellaneous, page elements, views, widgets etc... but also "New custom content".

When I have created "New custom content", my question is: where do i find it using phpMyAdmin?

My site crashed, but I can still get to my content this way to recover my data. Most of the content I can find this way, but there was one important thing i only wrote down in such a "Custom content" on the homepage panel page...
