  An alternative refined de Sitter conjecture giving rise to a natural
combination of the first and second derivatives of the scalar potential was
proposed recently by David Andriot and Christoph Roupec (Fortsch. Phys. 67
(2019) no.1-2, 1800105). In this work, we study the inflation models in a
general scalar-tensor theory with exponential and hyperbolic tangent forms of
potential as well as model with quantum corrected potential and examine whether
these three models of inflation can satisfy this further refining de Sitter
swampland conjecture or not. Regarding our analysis with proper choices of
parameters with proper choices of parameters $a,b=1-a$ and $q$, we find that
these three inflationary models can always satisfy this new refined swampland
conjecture. Therefore, all three inflationary models might all be in landscape
since the further refining de Sitter swampland conjecture is satisfied.
