Isohomoarbutin 是来自 Pyrola rotundifolia (Pyrolaceae) 全草本植物的天然产物。

Isohomoarbutin is a natural product from the whole herb of Pyrola rotundifolia (Pyrolaceae).

From the water-soluble constituents of the whole herb of Pyrola rotundifolia (Pyrolaceae), one novel phenolic glycoside dimer, pyrolaside A (1), and one novel phenolic glycoside trimer, pyrolaside B (2), together with two known phenolic glycosides homoarbutin (3) and Isohomoarbutin (4), were isolated. The structures were elucidated by spectroscopic analysis and confirmed with chemical degradation.CONCLUSIONS: In vitro tests for antimicrobial activity showed pyrolaside B (2) to possess significant activity against two Gram-positive organisms, Staphylococcus aureus and Micrococcus luteus[1].
