Two New Ellagitannin Metabolites, Carpinusin and Carpinusin from Carpinus laxiflora
摘要:
From the fresh leaves of Carpinus laxiflora (Betulaceae), two new hydrolyzable tannins, carpinusin (2) and carpinusnin (3), have been isolated, together with thirteen known hydrolyzable tannins and related compounds, and their structures were elucidated on the basis of physico-chemical evidence.
