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.
