    Triptinins A and B, two leukotriene D4 antagonistic 19(4→3)-abeo-abietanes from Tripterygium wilfordii.[Reference: WebLink]
    Bioassay-directed separation of an ethanolic extract of the roots of Tripterygium wilfordii furnished two new 19(4→3)-abeo-abietanes, triptinin A and Triptinin B, along with two known diterpenes, triptoquinone A and 11-hydroxy-14-methoxy-19(4→3)-abeo-abieta-3, 8, 11, 13-tetraen-19-oic acid, as leukotriene D4 antagonist constituents. The structures of these diterpenes were elucidated by spectroscopic methods.
