Abstract Three new quinolizidine alkaloids (1− 3), including one new naturally isoflavone
and cytisine polymer (3), along with 6 known ones were isolated from the ethanol extract of …

Twelve quinolizidine alkaloids were isolated from Sophora tonkinensis by means of silica
gel, preparative MPLC, and preparative HPLC. On analysis of NMR spectroscopic data, their …

Seventeen quinolizidine alkaloids, including a new matrine-type one, sophcence A (1), were
isolated from the roots of Sophora flavescens Alt. The structure of compound 1 was …

A new quinoline alkaloid, 5‐hydroxy‐6‐methoxy‐N‐methyl‐2‐phenylquinoline‐4‐one (1),
and seventeen known quinoline alkaloids (2–18) were isolated from the roots of Orixa …

Five new quinolizidine alkaloids, including three sparteine‐type alkaloids (1–3) and two
cytisine‐type alkaloids (4 and 5), along with four known ones, were isolated from the roots of …

Seventeen quinolizidine alkaloids, including two new ones, 5-hydoxy-7, 11-dehydromatrine
(1) and 11-hydroxylupanine (2), were isolated from the aerial parts of Sophora tonkinensis …

Four new quinolizidine alkaloids, including three matrine-type alkaloids, 8α-
