Picrasma quassioides (P. quassioides) has been widely used as a traditional Chinese medicine for clearing fever and detoxification. Previous phytochemical studies have identified a novel dihydrobenzofuran-type neolignan, picrasmalignan A, isolated from the stems of P. quassioides. In the present

Nigakialcohol A (1), as unusual cyclization ionone derivative, together with eight known ones (2-9), were isolated from the leaves of Picrasma quassioides (D. Don) Benn (Simaroubaceae). Their structures were elucidated by extensive spectroscopic analyses and comparison with literature data. Compound

A new dihydrobenzofuran-type neolignan, picrasmalignan A (1), and a new sesterterpene lactone, 2'-isopicrasin A (4), were isolated from the stems of Picrasma quassioides Bennet, along with four known compounds, comprising two neolignans, 2 and 3, a sesterterpene lactone, 5, and a flavonol, 6. The

Four new bis-beta-carboline alkaloids, quassidines A-D (1-4), together with a known alkaloid, picrasidine C (5), were isolated from the stems of Picrasma quassioides. Quassidine A (1) is the first reported bis-beta-carboline alkaloid possessing a novel cyclobutane moiety. The structures of the new
