The invention relates to a content detection method for the Naoxintong capsule. The Naoxintong capsule comprises 66 parts of astragalus root, 27 parts of red peony root, 27 parts of root of red-rooted salvia, 27 parts of Chinese angelica, 27 parts of Szechuan lovage rhizome, 27 parts of peach kernel, 13 parts of safflower, 13 parts of prepared Frankincense, 13 parts of prepared myrrh, 20 parts of suberect spatholobus stem, 27 parts of twotooth achyranthes root, 20 parts of cassia twig, 27 parts of mulberry twig, 27 parts of earthworm, 13 parts of scorpion, and 27 parts of leech. The main chemical components, namely hydroxy safflower yellow A, paeoniflorin, ferulic acid, salvianolic acid B and ligustilide, in the Naoxintong capsule are simultaneously measured by the UPLC (ultra-performance liquid chromatography) technique. Single chromatographic analysis can be completed in 24 minutes. Chromatographic peaks of the main components are well separate, RSD (relative standard deviation) in both precision and receptiveness is smaller than 2.0%, and the quality of Naoxintong capsule can be controlled comprehensively.
