<p><b>OBJECTIVE</b>To study the chemical constituents of Shiraia bambusicola.</p><p><b>METHOD</b>Column chromatography with silica gel was employed for the isolation and purification of constituents. The structures were elucidated by means of chemical and spectroscopic data.</p><p><b>RESULT</b>Seven compounds were obtained and identified as hypocrellin A (I), hypocrellin B (II), hypocrellin C (III), hypomycin A (IV), ergosterol (V), ergosterol peroxide (VI) and 1,8-dihydroxy anthraquinone (VII).</p><p><b>CONCLUSION</b>Compounds (IV) (VII) were separated from Shiraia bambusicola for the first time.</p>
