Abstract

From dried stems of Tinospora rumphii Boerl. (Menispermaceae), a monolignan glycoside, syringin (1), and a diterpene glycoside, borapetoside B (2), were isolated. The structures of 1 and 2 were elucidated by spectroscopic and enzymatic studies. The amino acid composition and content in ethanol extract of the stems have also been studied.
