The Myrsinaceae are known to produce and accumulate many benzoquinones. Among these are embelin (15), rapa-none (16), and maesaquinone (17) (Fig. 6.2). Maesanin (18), from the fruit of Maesa lanceolata, is a powerful antibiotic agent. A hot-water extract of the fruits is used locally in Africa to prevent cholera (Harbome, 1986). 

A few positive results were obtained on testing of 92 samples representing 56 species Ardisia crispa (1/2), Maesa japonica (1/3), M. lanceolata (1/4), Myrisine lesserliana, Tapcinosperma sp.
