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.
TL;DR: From the dried stems of Tinospora tuberculata BEUMEE (Menispermaceae), N-transferuloyl tyramine (1), n-cis-feruloyyl tyramerine (2), and a new phenolic glucoside, tinotuberide (6), were isolated as discussed by the authors.
Journal ArticleDOI
Studies on the Constituents of the Stems of Tinospora tuberculata BEUMEE, III. : New Diterpenoids, Borapetoside B and Borapetol B
TL;DR: In this paper, a new diterpene glucoside, borapetoside A (1), and its aglycone, Borapetol A (2), were isolated from the stems of Tinospora tuberculata BEUMEE as the bitter principles, and their structures were elucidated.
Journal ArticleDOI
Studies on the Constituents of the Stems of Tinospora tuberculata, IV. Isolation and Structure Elucidation of the Five New Furanoid Diterpene Glycosides Borapetoside C–G
TL;DR: In this paper, 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 Beumee (Menispermaceae).
Journal ArticleDOI
Studies on the constituents of Tinospora sinensis. I: Separation and structure of the new phenolic glycoside tinosinen
TL;DR: A new phenolic glycoside, tinosinen, was isolated from the fresh stems of Tinospora sinensis Merr on the basis of acid hydrolysis and spectral data as (E)-1-(3-hydroxy-1-propenyl)-3,5-dimethoxyphenyl 4-O-beta-D-apiofuranosyl-(1-->3)-beta- D-glucopyranoside.
Journal ArticleDOI
Studies on the constituents of the stems of Tinospora sinensis, II. . Isolation and structure elucidation of two new dinorditerpene glucosides, tinosineside A and B
TL;DR: Two dinorditerpene glucosides, tinosineside A (1) and B (2-O-acetyltinosinesides A, 2), were isolated from the fresh stems of Tinospora sinensis Merr..
