In this paper we study the non-Gaussian features of the primordialfluctuations in loop quantum cosmology with the inverse volume corrections. Thedetailed analysis is performed in the single field slow-roll inflationarymodels. However, our results reflect the universal characteristics ofbispectrum in loop quantum cosmology. The main corrections to the scalarbispectrum come from two aspects: one is the modifications to the standardBunch-Davies vacuum, the other is the corrections to the background dependentvariables, such as slow-roll parameters. Our calculations show that the loopquantum corrections make $f_{{\rm NL}}$ of the inflationary models increase0.1%. Moreover, we find that two new shapes arise, namely $\mathcal F_{1}$ and$\mathcal F_{2}$. The former gives a unique loop quantum feature which is lesscorrelated with the local, equilateral and single types, while the latter ishighly correlated with the local one.
