Abstract:
A phytochemical investigation of the leaves of Erythrophleum fordii Oliv. has led to the isolation
of three new cassaine-type diterpenoids, erythrofordin A (1), erythrofordin B (2) and erythrofordin C (3), as
well as a norcassaine diterpenoid with a novel skeleton, norerythrofordin A (4), and 27 known compounds
(5-31). The structures of 1-4 were elucidated on the basis of spectroscopic analysis. Selected compounds
from this plant were examined for anti-inflammatory activity. Taraxerol (16) displayed potent NO-reducing
activity in microglial cells, and gallic acid (27) exhibited excellent DPPH radical-scavenging effects. Crown
