The invention discloses a
deodorant, which comprises an active extract taking
eupatorium adenophorum as a
raw material, wherein the active extract is prepared by a method comprising the following steps of: (1) crushing dry
eupatorium adenophorum leaves, and screening the crushed
eupatorium adenophorum leaves with a 40 to 60-mesh
sieve to obtain eupatorium adenophorum
powder; and (2) putting the eupatorium adenophorum
powder obtained in the step (1) into an extraction kettle, adding a
solvent in an amount which is 5 to 6 times
mass of the eupatorium adenophorum
powder into the eupatorium adenophorum powder, soaking the eupatorium adenophorum powder for 5 to 7 days under the
room temperature condition, filtering the solution, repeatedly soaking the eupatorium adenophorum powder three to four times, combining the extracts, and reclaiming the extraction
solvent under reduced pressure to obtain concentrate with
solid content of 20 to 25 percent, namely the active extract. Because the
deodorant contains the active extract taking the eupatorium adenophorum as the
raw material, the
deodorant has the effects on deodorization and
bacteria inhibition, and enlarges the development and utilization range of the eupatorium adenophorum; and an application method of the eupatorium adenophorum extract in the deodorant is provided.
