Abstract

The invention discloses a determination method of a characteristic spectrum of Xiao shuan tong luo granules. A high performance liquid chromatography method is employed under the following chromatographic conditions: an octyl silane chemically bonded silica chromatographic column is employed, a phosphoric acid water solution is used as a mobile phase A and acetonitrile is used as a mobile phase B, detection wavelength is 258-262 nm, and gradient elution is carried out. The method can easily, quickly and accurately perform the determination of the characteristic spectrum of Xiao shuan tong luo granules under stable determination conditions. The method is more comprehensive in control on quality of the Xiao shuan tong luo granules and guarantees the effectiveness and uniformity of quality of the Xiao shuan tong luo granules.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicines, in particular to a method for measuring the characteristic spectrum of Xiaoshuan Tongluo granules. Background technique [0002] Xiaoshuan Tongluo Granule is a blood-regulating agent, which has the effects of promoting blood circulation, removing blood stasis, warming meridians and dredging collaterals. Clinically, it is mainly used for apoplexy caused by blood stasis blocking collaterals. Symptoms include sluggish expression, sluggish speech, cold hands and feet, and limb pain; ischemic stroke and hyperlipidemia patients. The prescription contains Chuanxiong, Salvia, Astragalus, Alisma, Panax notoginseng, Sophora japonica, Guizhi, turmeric, woody, borneol, and hawthorn, which are prepared through a series of processes. [0003] The quality standard of this product is recorded in the first part of the "Chinese Pharmacopoeia" 2015 edition. 1 Reference substance, rutin refer...
