One way to do this with the guix API is to get the derivation, then build it:

(use-modules (guix derivations) (guix store) (gnu packages bash))
(define package bash-minimal)
(define store (open-connection))
(define der (package-derivation store package))
(build-derivations store (list der))

Is that what you want?
