There are benzoic, oxalic and plicatic acids in pine and cedar. A lot of it is given off, particularly with cedar, in off-gassing. Oak gives you tanic and acetic acids.

All woods contain resins and some contain a combo that is toxic to animals. Oak, along with cherry and black walnut contain those types of resins which is why they aren't used as shavings for animals.

Who would have thunk it, but it's true. Pine decomposes very slowly
and oak
very quickly.

Yes. Beyond decomposition speed, pine needles are more acid and I
wonder if the sawdust and chips are not also. I suspect but don't know
for sure that the resins are not so beneficial to the garden soil.
Resin is likely what inhibits decomposition speed. Oak leaves are
superior and one suspects oak sawdust and chips are superior also
because of the deep root system of the quercus family that gathers
micronutrients.
