Five New β‐Carboline‐Type Alkaloids from Stellaria dichotoma var. lanceolata

Five new β‐carboline‐type alkaloids, dichotomines F–J (1–5, resp.), along with nine known compounds, dichotomides I, III, V, and VII (6–9, resp.), stellarines A and C (10–11, resp.), dichotomine B (12), glucodichotomine B (13), and 1‐acetyl‐3‐carboxy‐β‐carboline (14), were isolated from the roots of Chinese medicinal plant Stellaria dichotoma L. var. lanceolata. Their structures were determined by chemical and spectroscopic means. Compounds 12 and 13 exhibited moderate cytotoxicity.
