(S)-Pterosin B is found in green vegetables. (S)-Pterosin B is found as glycosides in the rhizomes of Pteridium aquilinum (bracken fern Pterosin B, a indanone found in bracken fern (Pteridium aquilinum), is an inhibitor of salt-inducible kinase 3 (Sik3) signaling. Pterosin B prevents chondrocyte hypertrophy and osteoarthritis in mice by inhibiting Sik3[1][2].
