Constituents of Wild Japanese Valerian Root. (1)

Abstract

In the survey of the root constituents of a valerian indigenous to Mt. Ibuki, central Honshu, a number of sesquiterpenoids have been isolated or detected. This valerian is characterized by containing sesquiterpenoids of the valerane skeleton (in particular, valeranone, cryptofauronol, and fauronyl acetate) in large quantities, but those of the kessane skeleton in minute amounts.
