Abstract

The leaves of Atalantia ceylanica have yielded four compounds including a novel benzaldehyde derivative, 2,4,5-trimethoxybenzaldehyde (1), and two acridone alkaloids: 1,5-dihydroxy-3-methoxy-10-methyl-9(10H)-acridinone (2) and 11-hydroxynoracronycine (3), 2 is a new alkaloid and constitutes one half of the dimeric alkaloid atalanine, whilst 3 is one half of ataline. In addition, the leaves were found to contain the pyranoflavone carpachromene (4).
