The invention discloses a method for extracting a lubricating anti-rust oil additive from moss, lubricating oil and anti-rust oil. The fat-soluble moss extraction additive is prepared by taking bryophytes as raw materials through a Soxhlet reflux method and an ultrasonic extraction method. The preparation process mainly comprises the specific steps of pretreatment, solid-liquid extraction, ultrasonic extraction, filtration, evaporation and the like. The fat-soluble moss extraction additive is prepared for the first time, and it is found that the fat-soluble moss extraction additive can have good friction and loss reduction, corrosion prevention and corrosion inhibition effects on such acting metals as 20CrMnTi steel at the same time. By means of the poly-alpha-olefin lubricating oil containing the moss extraction additive, the friction coefficient of 20CrMnTi carburizing steel can be reduced by 72.22% at most under the load of 10 N, the abrasion rate is reduced by 73.77%, and the corrosion resistance and dura
