genus has been claimed for the significant contribution in pharmacological activities.
The increase in the amount of the publication and patents (Figs. 14.1 and 14.2) in the
last few years evinced that the scientific attention toward the Alstonia genus is
increasing in a vast manner. Hence, the present book chapter will help to obtain a
better understanding of the pharmaceutical application of Alstonia-derived
phytochemicals.
This chapter mainly deals with the following species namely A. scholaris, A.
macrophylla, A. boonei, A. angustifolia, A. venenata, A. yunnanesis. A. spatulata,
A. rupestris, A. rostrata, A. pneumatophora, A. penangiana, A. mairei, A. congensis,
