Two new phenolic compounds, Schitenoside A (1) and Schitenoside B (2), have been isolated together with six known compounds: 3,4-dihydroxyphenethyl alcohol-4-O-β-D-glucopyranoside (3), 2-(3-hydroxy-4-methoxyphenyl) ethanol 1-O-α-L-rhamnopyranosyl-(1→2)-β-D-glucopyranoside (4), benzyl 7-O-β-D-xylopyranosyl-(1→6)-β-D-glucopyranoside (5), 2-hydroxybenzoic acid (6), m-hydroxybenzoic acid (7) and trans-caffeic acid (8), from the Schizonepeta tenuifolia. Their structures were elucidated by spectroscopic analysis. Compounds (3-7) were isolated from Schizonepeta genus for the first time. Compounds 1 and 2 showed a week antibacterial activity against four test strains, involving both Gram-positive and Gram-negative bacteria .
