Abstract

Two novel cassane‐type diterpenes, named magnicaesalpin (1) and neocaesalpin O (2), together with three known compounds, caesalmin D (3), caesalmin E (4), and neocaesalpin L (5), were isolated from the MeOH extract of seeds of Caesalpinia magnifoliolata Metc. Their structures were determined by spectroscopic methods, (1D‐ and 2D‐NMR, HR‐EI‐MS) and X‐ray analysis, as well as by comparison of their spectral data with those of related compounds.
