Phenolic glycosides from Boschniakia himalaica

Two new phenylethanoid glycosides, himalosides A (1) and B (2), were isolated from the whole plant of Boschniakia himalaica, together with four known compounds. Their structures were elucidated on the basis of spectral and chemical evidences. Himaloside A (1) and (+)-lariciresinol 4′-O-β-d-glucopyranoside (4) exhibited antibacterial activity with the MIC values at 50 and 25 μg/mL against Staphylococcus aureus and S. epidermidis, respectively.
