- A STUDY OF THE HERB Aerva lanata. III. ALKALOIDS
-
Four new alkaloids - aervine (10-hydroxycanthin-6-one), methylaervine (10-methoxycanthin-6-one), aervoside (10-β-D-glucopyranosyloxycanthin-6-one), and aervolanine (3-(6-methoxy-β-carbolin-1-yl)propionic acid), and also the known alkaloids canthin-6-one and 3-(β-carbolin-1-yl)propionic acid have been isolated from the herb Aerva lanata Juss.Their structures have been established on the basis of chemical and spectral characteristics.

- Studies on the Constituents of Picrasma quassioides BENNET. III. The Alkaloidal Constituents
-
A new β-carboline alkaloid, named picrasidine E(I), was isolated from the wood of Picrasma quassioides BENNET (Simaroubaceae) together with seven known alkaloids, 1-methoxycarbonyl-β-carboline (II), 1-ethoxycarbonyl-β-carboline (III), 1-formyl-β-carboline (IV), 1-hydroxymethyl-β-carboline (V), β-carboline-1-propionic acid (VI), 4,5-dimethoxy-canthin-6-one (VII), and 5-hydroxy-4-methoxycanthin-6-one (VIII).These structures were elucidated on the basis of spectroscopic and chemical evidence.Keywords - Picrasma quassioides; Simaroubaceae; wood; picrasidine E; β-carboline type alkaloid; canthin-6-one type alkaloid.
