Phenolic glycosides from Boschniakia himalaica

Abstract 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.
