Polyporenic acid C 是从茯苓中分离出的一种羊毛甾烷型三萜，可通过死亡受体介导的凋亡途径诱导细胞凋亡，有用于肺癌的研究潜力。

Polyporenic acid C shows inhibitory activity against human collagenase.

Polyporenic acid C (PPAC) significantly reduced cell proliferation via induction of apoptosis as evidenced by sub-G1 analysis, annexin V-FITC staining, and increase in cleavage of procaspase-8, -3, and poly(ADP-ribose)-polymerase (PARP). However, unlike our previously reported lanostane-type triterpenoid, pachymic acid, treatment of cells with PPAC was not accompanied by disruption of mitochondrial membrane potential and increase in cleavage of procaspase-9. Further, PPC-induced apoptosis was inhibited by caspase-8 and pan-caspase inhibitors but not by a caspase-9 inhibitor.
