Abstract

Pyrocallianthasides A (1) and B (2), a new dimer and a new mono‐deglucosyl trimer of homoarbutin (=4‐hydroxy‐3‐methylphenyl β‐glucopyranoside), and callianthaside A (3), a new ursane‐type triterpene glycoside, together with three known phenolic glycosides and three known ursane‐type triterpenoids, were isolated from the whole plants of Pyrola calliantha. The structures of 1–3 were elucidated by chemical and spectroscopic methods.
