Abstract

The invention relates to a determination method of the content of an active ingredient of a Pingxiao capsule. The determination method includes preparation of a reference solution, preparation of a test solution and formulation of high performance liquid chromatography conditions, wherein naringin content is not less than 2.13mg / particle and neohesperidin content is not less than 1.22mg / particle. The determination method is simple, safe and reliable, and is capable of faithfully representing product content and quality; the determination method is suitable for industrial daily production and inspection.

Description

technical field [0001] The invention relates to the field of medicine, in particular to a method for determining the content of active ingredients in Pingxiao capsules. Background technique [0002] Existing Chinese patent medicine Pingxiao Capsule is a kind of commonly used antitumor Chinese patent medicine. [Content Determination] of Pingxiao Capsules recorded in Pharmacopoeia and Ministry Standards: Take 30 capsules of this product, pour out the contents, accurately weigh, grind finely, take about 4g of powder, accurately weigh, put in a 100ml conical flask with a stopper Add 20ml of chloroform and 1ml of concentrated ammonia solution precisely, seal it tightly, weigh it, soak it in cold for 48 hours, or extract it by ultrasonic for 40 minutes, weigh it, make up the lost weight with chloroform, shake it fully, filter it, and measure it precisely Filtrate 10ml, put in separatory funnel, extract 4 times with sulfuric acid solution (0.5mol / L), each 10ml, extract is all filt...
