title: Two new tetracyclic triterpenoids from the barks of Melia azedarach.
abstract: Two new tetracyclic triterpenoids, together with 21 known compounds, were isolated from the barks of Melia azedarach. The structures of new compounds were elucidated by the means of HRESIMS, 1D NMR, 2D NMR, and X-ray crystallography analysis.
