Mahesh,
There's no AnyConnect-specific sort of macro command to do that. If you are just looking to reset everything in the config, you can use the configure factory-default command.
Otherwise, you'd just have to remove the individual sections / lines with "no..." commands. Note that where things are in sections ("group-policy"and "tunnel-group" for example), you can delete the section in a single "no" command without having to go into each subsection line and remove them individually.
You'd also need to delete any profiles (xml files) you had created and AnyConnect images (pkg) files on the disk to be totally complete.
