Two new diterpenoids from the root nodules of Pygmacopremna herbacea (Roxb.) Moldenke

Phytochemistry Letters 4 (2011) 109–112

Bharangin (1) analogues, bharangi-g-lactone (2) and bharangi-d-lactone (3) were isolated from the ethyl acetate extract of the root nodules of the indigenous medicinal plant Pygmacopremna herbacea (Roxb.) Moldenke (Gantubharangi). Compound 3 was also prepared from bharangin by treating with 2 N KOH in methanol at room temperature. The structures of the compounds were established by means of spectral data analysis, including high field 2D NMR studies.
