A new diterpenoid was isolated from the ethanolic extract of the dried root bark of Tripterygium wilfordii Hook.f. It is the first example of abietane diterpenoid glycoside isolated from Tripterygium wilfordii Hook.f. Its structure was identified to be 11-O-β-D-glucopyranosyl neotriptophenolide based on spectral methods.
