The invention discloses cannabis sailve extract which is extracted from flowers and leaves of industrial cannabis sailve and rich in cannabidiol (CBD) and a preparation method of the cannabis sailve extract. The preparation method includes the steps that firstly, heat dry treatment is conducted on the flowers and leaves of cannabis sailve, then a subcritical butane extraction technology is adopted, ethyl alcohol serves as entrainer, and crude extract which is rich in cannabidiol is obtained; the crude extract is dissolved in an ethanol solution of a certain proportion, and low-temperature odstearynowanie is conducted; centrifugation is conducted through a centrifugal machine, or filtering is conducted through a filtering machine to remove waxiness; activated carbon is added to liquid supernatant, and decolorization and filtration are conducted; finally, filtrate is subjected to rotary evaporation to remove ethyl alcohol, and the cannabis sailve extract rich in CBD can be obtained. The obtained cannabis sailve extract is high in CBD content and good in color and has a good physiological property. The method is simple in process, industrialized application is achieved easily, and development and utilization of high value-added products of Cannabis sailve are promoted.
