Nine new phenylpropanoids, rashomonic acids A—D (1—4) and meehaniosides A—E (5—9), along with four known compounds were isolated from Meehania urticifolia. The structure of each new compound was elucidated based on the results of spectroscopic analyses. Compounds 3—8 showed moderate hyaluronidase inhibitory activity with IC50 values of 183—1049 μM.
