Phloroglucinol diglycosides accompanying hydrolyzable tannins from Kunzea ambigua

Phytochemistry, 2008
Six phloroglucinol diglucosides-kunzeaphlogins A-F (1-6) and a hydrolyzable tannin, kunzeatannin A (7)-were isolated along with 10 known polyphenols from the leaf extract of Kunzea ambigua. Structural elucidation of these compounds was based on spectroscopic analyses and chemical properties.

Combreglutinin, a Hydrolyzable Tannin from Combretum glutinosum

Journal of Natural Products, 1994
Combreglutinin [4], a hydrolyzable tannin, was isolated from the leaves of Combretum glutinosum, and its macrocyclic structure was established on the basis of 1 H- and 13 C-nmr and 2D nmr spectroscopic data and by chemical methods. The three known tannins 2,3-(S)-hexahydroxydiphenoyl-D-glucose [1], punicalin [2], and punicalagin [3] were also ...
