Such turpentine is called wood turpentine.
Pine tar is a form of wood tar produced by the high temperature carbonization of pine wood in anoxic conditions (dry distillation or destructive distillation). The wood is rapidly decomposed by applying heat and pressure in a closed container; the primary resulting products are charcoal and pine tar .
Pine oil is a higher boiling fraction from turpentine. Both synthetic and natural pine oil consists mainly of α-terpineol, a C10 alcohol (b.p. 214–217 °C).
