  We consider bosonisation of the low-energy QCD based on integrating the
anomaly of the extended chiral (E$\chi$) transformation which depends both on
pseudoscalar meson and scalar diquark fields as parameters. The relationship
between extended chiral and usual chiral anomalies and related anomalous
actions is studied. The effective action for the extended chiral field $\U$
depending on complete set of anomalous generators of the E$\chi$-transformation
is given. The terms of this effective action relevant to interaction of pions
and $\bar 3_c$ scalar diquarks are written down explicitly.
