Termitomenins F and G, Two New Lignan Glucosides from Terminalia chebula var. tomentella (Kurz) C. B. Clarke

The extensive chemical investigation on the branches and leaves of Terminalia chebula var. tomentella (Combretaceae) led to the isolation of two new lignan glucosides with a furofuran skeleton, termitomenins F ( 1 ) and G ( 2 ). In addition, 19 known compounds including five lignan glucosides ( 3 – 7 ), six hydrolyzable tannins ( 8 – 13 ) and eight simple phenolics ( 14 – 21 ) were also identified. Their structures were determined by...
