Dimeric Diterpenes from the Roots of the Mangrove Plant Ceriops tagal

Abstract

Three new dimeric diterpenses. tagalsin L (1), tagalsin NI (2), and tagalsin N (3) were isolated front the roots of the mangrove plant Ceriops tagal. Their structures and relative configurations were elucidated by means of extensive IR, NMR, and MS analyses.
