A NEW TANNIN FROM YOUNG STEM BARK OF CAESALPINIA PULCHERRIMA

From the inner stem bark of three months old plants of Caesalpinia pulcherrima a new ellagitannin has been isolated which is unique in having a combination of condensed and hydrolysable tannin units in the molecule. Its structure has been established on the basis of analytical, degradative and spect...

Zusammenfassung:From the inner stem bark of three months old plants of Caesalpinia pulcherrima a new ellagitannin has been isolated which is unique in having a combination of condensed and hydrolysable tannin units in the molecule. Its structure has been established on the basis of analytical, degradative and spectroscopic evidences.
