Three new ellagitannins, prostratins A, B and C, along with eleven known polyphenols including three hydrolyzable tannin oligomers (rugosins D, E and G), have been isolated from the leaves of Euphorbia prostrata AIT. A hydrolyzable tannin trimer, prostatin B, and two dimers, rugosins D and E, were also obtained from the leaves of Loropetalum Chinense OLIV.
