Problems solved by technology

Commonly used processes such as percolation, cold immersion, and water extraction and alcohol precipitation for the extraction of Panax notoginseng, but such extraction processes are time-consuming and have low extraction efficiency, resulting in high process costs and low content of active ingredients
In addition, traditional extraction methods use organic solvents as extractants, resulting in more solvent residues in the extracts contained in toothpaste.

Abstract

The invention discloses a preparation method of a pseudo-ginseng extract for toothpaste. In the method, pseudo-ginseng crude medicines are crushed, an aqueous two-phase system formed by a natural eutectic reagent and a salt solution is used as an extraction agent, centrifugation is performed after being processed by microwave-ultrasound with ultrasonic power of 100-400W and microwave power of 100-200W at the temperature of 20-50 DEG C, a bottom phase taken out after centrifugation is the pseudo-ginseng extract for the toothpaste. By using the preparation method provided by the invention, an extract yield can be improved, and meanwhile extraction time can be significantly shortened. In addition, the eutectic reagent which is green, environment-friendly and good in physiological compatibility is used as the extraction agent, so that the condition that the extract does not include organic solvent is ensured, and the extract is reduced in irritation so as to be more accordant with the requirement of environment protection. By adding the pseudo-ginseng extract acquired according to the preparation method provided by the invention into the toothpaste, improvement effect of the toothpaste on symptoms such as dental ulcer, dental plaque, gingivitis and gingival bleeding can be significantly enhanced.

Description

technical field [0001] The invention relates to the technical field of fine chemicals, more specifically, the invention relates to a method for preparing a toothpaste extract of Panax notoginseng. Background technique [0002] Panax notoginseng is Araliaceae plant Panax notoginscng (Burk.) F. H. Chen's dry root, also known as Shanqi, Jinbuhuan, Tianqi and so on. Mainly produced in Yunnan, Guangxi and other places, wild or cultivated. Radix Notoginseng is sweet in nature, slightly bitter, warm. Mainly the liver, stomach, and large intestine meridian, it has the functions of "removing blood stasis, stopping bleeding, reducing swelling and relieving pain". In terms of its function, "Compendium of Materia Medica" records Panax notoginseng: "Stop bleeding, disperse blood, and relieve pain. For those who have wounds from golden blade arrows, sores from falling sticks, and bleeding that does not stop It also treats hematemesis, hemorrhage, bloody dysentery, metrorrhagia, menst...
