Problems solved by technology

[0006] Regarding the extraction of purslane, it has been reported in the literature that it has been heated and extracted with water or alcohol. This method is simple and easy, but the heating process will destroy the active ingredients of purslane; Efficiency has been improved, but both will cause super high local temperature, destroy active ingredients, and the cost of equipment in the industrialization process is relatively high; there are reports in the literature that adding hydrolytic enzymes to help extraction, hydrolytic enzymes as additional chemicals, will It has a great impact on the chemical composition of the finished product, and increases the difficulty of product quality control, which is not conducive to ensuring the stability of the product between different batches, and the activity difference between batches fluctuates greatly. If it is used as the main active ingredient, it cannot be guaranteed that every All batches are safe and effective

Embodiment 1

[0044] Purslane (Shiping City, Yunnan Province) medicinal material was taken, washed with normal temperature water, and air-dried.

[0045] A preparation method of purslane extract, comprising the following steps:

[0046] S1, low-temperature extraction step: prepare 30% ethanol / water mixture with distilled water and medicinal ethanol as an extraction solvent, take 10Kg of air-dried purslane and pulverize it and add it to the extraction tank, then add 30Kg of the extraction solvent to the extraction tank, Control the temperature in the extraction tank at 20°C, the stirring speed of the agitator in the extraction tank is 90 rpm, and extract in this state for 24 hours to obtain a crude extract;

[0047] S2, the filtering step: the crude extract is filtered through a 0.22 μm filter membrane to remove the purslane drug residue, and 35 Kg of a clear and transparent wine red filtrate is obtained;

[0048] S3, flocculation step: prepare a flocculant solution with a content of 1%, th...

Abstract

The invention discloses a preparation method of a purslane extract. The preparation method includes the steps of low-temperature extraction, filtration, flocculation, decoloration and low-temperaturedrying. The preparation method is simple and feasible, the energy consumption is significantly lower than that of a conventional extraction method, and the method is suitable for industrial production; the purslane extract obtained by the method ensures that chemical components of purslane are not destroyed to the greatest extent, main components polysaccharides and organic acids have high stability in different batches, do not contain prohibited substances norepinephrine and dopamine, and have not skin phototoxicity, and the purslane extract can be used as the active component of skin care products and pharmaceutical auxiliaries and plays anti-inflammatory, anti-irritating, allergy-relieving and other functions.

Description

technical field [0001] The invention relates to a preparation method and application of purslane extract. Background technique [0002] Purslane (Portulaca oleracea L.) is an annual succulent herb of the family Portulacaaceae, which was first recorded in "Shen Nong's Herbal Classic". Because of its green leaves, red stems, yellow flowers, white roots, and black seeds, it is also known as five-element grass or five-element dish, and purslane is widely planted as a vegetable all over the world. Purslane extract has been widely developed and used for its good biological properties and safety, and it is added as an anti-inflammatory and soothing ingredient in many cosmetics. [0003] The Chinese Pharmacopoeia records that the aerial part of purslane is used as medicine. It has the effect of clearing away heat and detoxification, cooling blood and stopping bleeding. Classes, flavonoids and other ingredients. It also contains hormonal ingredients such as norepinephrine and dopa...
