## Abstract Five new furanoid diterpene glycosides, named borapetoside C (1), D (2), E (3), F (4), and G (5), were isolated from the stems of __Tinospora tuberculata__ Beumรฉe (Menispermaceae). The structures of 1โ5 were elucidated by chemical and spectroscopic methods.
Swertisin was first isolated from the whole herb of Swertla japonica (Fam: Gentianaceae) by Nakaolti (l), who proposed the empirical formula Cl3HlGO G H20. Subsequently, Asahlna et al. revised the formula for swertisin to C23H24Oll(2). No further investigations, however, have been made. We now found
