| Abstract: | Two new unsymmetric tetracyclic triterpenoids onocer-7-ene-3α,21β-diol and onocer-7-ene-3β,21α-diol together with sitosterol, δ-amyrin and δ-amyrone have been isolated from Cissus quadrangularis. The structures of the new compounds were elucidated on the basis of 1H NMR, mass spectral and chemical evidence. |
