  A chemical examination of mylobalans (the fruits of Terminalia chebula RETZ., Combretaceae) has led to the isolation and characterization of punicalagin (1), terflavin A (2) and a new ellagitannin named terchebulin (3), which possesses a anovel tetraphynylcarboxylic acid (terchebulic acid) moiety. Furthermore, from the leaves of T. chebula, a series of biogenetically related hydrolyzable tannins, terflavins B (7), C (9) and D (10), punicalagin (1) and punicalin (8), have been isolated and structurally elucidated. The concomitant isolation of terflavins A (2) and B (7) provides biogenetic evidence that the tervhebulic acid moiety is derived by an oxidative carbon-oxygen coupling of adjacent flavogallonic acid and gallic acid esters.

  对乳香果（Terminalia chebula RETZ.，Combretaceae）的化学检测，分离并鉴定出番石榴素（1）、terflavin A（2）和一种名为terchebulin（3）的新鞣花单宁，后者具有一种新的四苯基羧酸（terchebulic acid）部分。此外，从乳香果的叶子中分离出一系列生物遗传相关的可水解单宁，terflavins B（7）、C（9）和D（10）、番石榴素（1）和番石榴素（8），并阐明了其结构。同时分离出的terflavins A（2）和B（7）提供了生物遗传学证据，证明terchebulic acid部分是由相邻的黄酮没食子酸和没食子酸酯的氧化碳-氧偶联产生的。
