Five new canthin-6-one alkaloids, 9,10-dimethoxycanthin-6-one, 10-hydroxy-9-methoxycanthin-6-one, 11-hydroxy-10-methoxycanthin-6-one, 5,9-dimethoxycanthin-6-one and 9-methoxy-3-methylcanthin-5,6-dione were isolated from the bark and wood of Eurycoma longifolia, along with six known canthin-6-one alkaloids and two known β-carboline alakloids.Their structures were determined from spectroscopic data and other chemical evidence.
