Two new diterpenoids, neobharangi-d-lactone (1) and bharangi quinone (2) along with two known
compounds neobharangin (3) and bharangin (4) were isolated from the ethyl acetate extract of root
nodules of Pygmacopremna herbacea. The structures of the new compounds were established by 1D and
2D NMR spectroscopic data.
