Abstract

On the basis of traditional Chinese medicine theory, the present invention utilizes modern medicine theory to develop an active extract composition of Dipsacus and Radix Notoginseng with simplified formula, clear active ingredients, definite curative effect and controllable quality and its preparation and treatment. Application in medicine for fracture and osteoporosis. The active extract is composed of total saponins of Dipsacus and total saponins of Panax notoginseng, the weight ratio of which is 1:0.2-15, and the optimum weight ratio is 1:0.5-5.

Description

Technical field: [0001] The invention relates to an active extracting composition of Dipsacus and Panax notoginseng and its application in medicine. The extracting compositions are total saponins of Radix Dipsaceae and total saponins of Panax notoginseng. The composition can be used to prepare medicines for treating fractures and osteoporosis. Background technique: [0002] Fracture is a common injury, and the elderly and postmenopausal women suffer from rapid reduction of bone mass and increased bone fragility after osteoporosis, and fractures can occur with minor trauma. American scholars have reported that about 1 / 3 to 1 / 2 of postmenopausal women have fractures due to osteoporosis, and about 1.3 million fractures occur every year, costing about 10 billion US dollars each year. Shanghai scholars reported 10,429 elderly people over 60 years old with a fracture incidence rate of 15.6%. And after the fracture of the elderly, due to poor healing, there are many complication...
