ABSTRACT
<p><b>OBJECTIVE</b>To study the chemical constituents from Hypericum perforatum.</p><p><b>METHOD</b>Compouds were isolated by chromatographic techniques. Their structures were identified by spectral methods. The inhibitory activity of recombinant human PTP1B was evaluated.</p><p><b>RESULT</b>Nine compounds were elucidated as D-Mannitol (1), 1,2-benzenedicarboxylic acid bis(1-methylpropyl) ester (2), (7E, 6R,9S)-9-hydroxy-4,7-megastigmadien-3-one (3), (6S,9R)-roseoside (4) , 2,6-dimethoxy-4-hydroquinone-l-O-beta-D-glucopyranoside (5), 2,6-di-methoxy-4-hydroxybenzyl alcohol 1 -O-beta-D-glucopyranoside (6), syringate 4-O-beta-glucopyranoside (7), hypericin (8), skyrin-6-0-beta-D-glucopyranoside (9) , (R)-2,3-dihydroxypropyl 3,4-dihydroxy-benzoate (10). At a concentration of 2 micromol x L(-1), compound 8 inhibited recombinant human PTP1B with inhibitory rate of 96.4% and IC50 of 2.5 micromol x L(-1).</p><p><b>CONCLUSION</b>compound 10 was new, compounds 2-4, 7 were obtained from Hypericum for the first time and compounds 5-6 was isolated from this plant for the first time. Compound 8 showed remarkable PTP1B inhibitory activity.</p>
