Studies on the constituents of the stems of Tinospora tuberculata Beumee. I. N-trans- and N-cis-feruloyl tyramine, and a new phenolic glucoside, tinotuberide.
Studies on the constituents of the stems of Tinospora tuberculata Beumee. I. N-trans- and N-cis-feruloyl tyramine, and a new phenolic glucoside, tinotuberide.
From the dried stems of Tinospora tuberculata BEUMEE (Menispermaceae), N-transferuloyl tyramine (1), N-cis-feruloyl tyramine (2), and a new phenolic glucoside, tinotuberide (6), were isolated. The structure of 6 was elucidated as 3-(4'-β-D-glucopyranosyloxy-3', 5'-dimethoxyphenylmethoxy)-2-trans-propen-1-ol.
