摘　　要：Two new saponins named davuricoside H and davuricoside K were isolated from the whole plant of Lysimachia davurica. The structures of davuricoside H and davuricoside K were determined by 1-D and 2-D NMR, MS techniques, and chemical methods to be 3β,16α ,28-trihydroxy-olean-12-en-30-oic acid-3-O-β-D-glucopyranosyl-（ 1→2 ）- [β-D-glucopyranosyl-（ 1 → 4 ） ] -α-L-arabinopyranoside and 3β,16or ,28-trihydroxy-olean-12-en-30-oic acid-3-O-{β-D- glucopyranosyl- （ 1 →2 ） - [β-D-glucopyranosyl- （ 1 →4 ） ] -α-L-arabinopyranosyl } -30-O-β-D-glucopyranosyl-ester.Two new saponins named davuricoside H and davuricoside K were isolated from the whole plant of Lysimachia davurica.
