- Canthin-6-one and β-carboline alkaloids from Eurycoma harmandiana
-
Two alkaloids, canthin-6-one 9-O-β-glucopyranoside and 7-hydroxy-β-carboline 1-propionic acid, were isolated from the roots of Eurycoma harmandiana, together with the five known canthin-6-one alkaloids, 9-hydroxycanthin-6-one, 9-methoxycanthin-6-one, 9.10-dimethoxycanthin-6-one, canthin-6-one and canthin-6-one N-oxide, and the two known β-carboline alkaloids, β-carboline 1-propionic acid and 7-methoxy-β-carboline 1-propionic acid. Their structures were based on analyses of spectroscopic data.
