Chemical Composition and Anti-malarial Activity of the Fraction from Dryopteris crassirhizoma Nakai
The rhizome and leftover petiole of Dryopteris crassirhizoma Nakai is a traditional Chinese medicine to cure flu and verminosis. It is recorded in Chinese pharmacopoeia under the name of Mianma Guanzhong [1]. A chemical standardized fraction has been obtained from Mianma Guanzhong. Its anti-malarial efficacy was evaluated with Peter's test on suppressive Plasmodium berghei in a mouse malaria model. The ED50 is 59.74 mg/Kg on mice with K173 and the ED50 is 111.22 mg/Kg on mice with RC/K173. Four major compounds, dryocrassin ABAA, ABPA, ABBA, and ABBP were detected in this fraction by LC/MS/MS.
