Undescribed phenylpropanoid and a dimeric sesquiterpenoid possessing a rare cyclobutane ring from Tinospora sinensis
A rare dimeric sesquiterpenoid (tinosposinoside, 1) and a phenylpropanoid (cordifolioside C, 2), two undescribed metabolites, were isolated from the methanolic extract of the stems of Tinospora sinensis together with thirteen known compounds. This is the second example of a sesquiterpene dimer where two monomers linked together through a cyclobutane ring, possibly generated through [2þ2] cycloaddition. The structures of 1 and 2 were elucidated by NMR and mass techniques.
