Hi,

use a WMSCapabilitiesStore, and you'll have the abstract in each record's 
"abstract" field. From 
http://geoext.org/lib/GeoExt/data/WMSCapabilitiesReader.html

* recordType – Array | Ext.data.Record An array of field configuration objects 
or a record object. Default isGeoExt.data.LayerRecord with the following 
fields: name, title, abstract, queryable, opaque, noSubsets, cascaded, 
fixedWidth, fixedHeight, minScale, maxScale, prefix, formats, styles, srs, 
dimensions, bbox, llbbox, attribution, keywords, identifiers, authorityURLs, 
metadataURLs. The type of these fields is the same as for the matching fields 
in the object returned fromOpenLayers.Format.WMSCapabilities::read().

Regards,
Andreas.
