Abstract

The invention relates to the quality inspection field of traditional Chinese medicine, in particular to a quality control method of compound preparation of an active extracting compound containing Duan-xu and panax notoginseng. The invention establishes the quality control method on a capsule and a tablet of the active extracting compound containing the Duan-xu and the panax notoginseng. The the quality control method comprises identification, dissolving out rate, the content mensuration of total saponin, and the content mensuration of akebiaquinata saponin D, panax notoginseng saponin R1, ginsenoside Rg1, and ginsenoside Rb1. The quality control method which has good reproducibility and reliability can be used in the quality control of a compound capsule and a compound tablet of the active extracting compound containing the Duan-xu and the panax notoginseng.

Description

Technical field: [0001] The invention relates to the field of quality control of natural medicines, in particular to a method for quality control of a compound preparation containing an active extraction composition of Radix Dipsacae and Panax notoginseng. Background technique: [0002] The active extract composition of Dipsacus and Sanqi refers to the composition of total saponins of Radix Dipsacae and Panax notoginseng, which are the active ingredients of Dipsacaceae and Sanqi. Dipsacus is the dry root of Dipsacus asperoides C.Y.Cheng et T.M.Ai. Tool invigorates liver and kidney, strengthens muscles and bones, continues fractures and injuries, and stops metrorrhagia. For soreness of the waist and knees, rheumatism arthralgia, diseases such as injury from falling. Modern studies have shown that the active ingredient of Dipsacus tonifying kidney and strengthening bones is the total saponins of Dipsacus. Panax notoginseng is the dry root of Panax notoginseng (Burk.) F.H.Ch...
