Embodiment 1

[0030] Weigh 1 kg of fresh purslane, crush it into a purslane slurry with a pulverizer; add ethanol with a volume percentage of 75% according to the mass-volume solid-liquid ratio of 1:3 (g / ml), and stir and extract at a feed liquid temperature of 70°C 2h, filter out the purslane residue to obtain filtrate 1; rotate the above filtrate 1 until the filtrate has no alcohol taste, then add water to make up the volume of the original filtrate to obtain filtrate 2; add the mass compounding ratio to the filtrate 2: The mass percentage of 1 is the composite decolorizing agent of activated carbon and activated clay of 0.5wt%, decolorizes at 80 ℃ for 30min, and filters out activated carbon with 200nm ceramic membrane; Use the filtrate with the cut-off molecular weight of 20nm nanofiltration membrane to be less than 150-300, obtain Filtrate three; Add 30wt% butanediol based on the total mass of the whole system as a humectant in the above-mentioned filtrate three, then add 0.3wt% colloida...

Embodiment 2

[0032] Weigh 1 kg of fresh purslane, crush it into purslane slurry with a pulverizer; add ethanol with a volume percentage of 75% according to the mass-volume solid-liquid ratio of 1:5 (g / ml), and stir and extract at a temperature of 70°C for 2 hours. Filter out the purslane residue to obtain filtrate 1; rotate the above filtrate 1 until the filtrate has no alcohol taste, then add water to restore the volume of the original filtrate to obtain filtrate 2; Mass percentage is the compound decolorizing agent of activated carbon and activated clay of 0.5wt%, decolorizes at 80 ℃ for 30min, and filters out activated carbon with 200nm ceramic membrane; Use the filtrate of molecular weight less than 150-300 to cut off with the nanofiltration membrane of 20nm, obtain filtrate three In above-mentioned filtrate three, add 30wt% butanediol based on the gross mass of whole system as humectant, then add 0.3wt% colloidal silver ion based on the gross mass of purslane extract and the whole syst...

Embodiment 3

[0034] Weigh 1 kg of fresh purslane, crush it into purslane slurry with a pulverizer; add ethanol with a volume percentage of 75% according to the mass-volume solid-liquid ratio of 1:10 (g / ml), and stir and extract at a feed liquid temperature of 70°C 2h, filter out the purslane residue to obtain filtrate 1; rotate the above filtrate 1 until the filtrate has no alcohol taste, then add water to make up the volume of the original filtrate to obtain filtrate 2; add the mass compounding ratio to the filtrate 2: The mass percentage of 1 is the compound decolorizing agent of activated carbon and activated clay of 0.5wt%, decolorizes 30min at 80 ℃, and filters out activated carbon with 200nm ceramic membrane; Use the filtrate of 20nm nanofiltration membrane cut-off molecular weight to be less than 150-300, obtain Filtrate three; Add 30wt% butanediol based on the total mass of the whole system as a humectant in the above-mentioned filtrate three, and then add 0.3wt% colloidal silver io...

Abstract

The invention discloses a preparation method of a herba portulacae extracting solution. The preparation method comprises steps as follows: fresh herba portulacae is weighed and crushed into herba portulacae pulp by a crusher; ethanol with the volume percentage being 50%-75% is added, the mixture is stirred at the temperature of 60-80 DEG C, extracted for 1-3 h and filtered, filtrate I is obtained and then distilled, ethanol is recovered, water is added until the volume of original filtrate I is reached, and filtrate II is obtained; an activated carbon and activated clay compounded decolorizing agent is added to the filtrate II, the filtrate II is decolorized for 20-40 min at the temperature of 20-80 DEG C, and activated carbon is filtered out with a ceramic membrane; filtrate with the molecular weight smaller than 150-300 is intercepted with a nanofiltration membrane, and filtrate III is obtained; a humectant is added to the filtrate III, then, a preservative is added, and the herba portulacae extracting solution is obtained. The preparation process of the herba portulacae extracting solution is simple to operate, and industrial production is facilitated; the herba portulacae extracting solution prepared with the preparation method has high anti-UVA (ultraviolet A), free radical scavenging and in-vitro oxidation resistance characteristics and cannot cause inflammatory factors.

Description

technical field [0001] The invention relates to the field of cosmetics, in particular to a preparation method of purslane extract. Background technique [0002] Photoaging is the most important form of external skin aging, and ultraviolet radiation, especially UVA, is the main cause of skin photoaging. Skin photoaging is irreversible damage and has become the "public enemy number one" of beauty-loving women. It is of great significance to develop natural plant materials with good anti-UVA effects. [0003] Purslane (Portulacaoleracea L) is an annual succulent herb, also known as purslane, five-element dish, and longevity dish. It is one of the 78 wild plants with the same origin in medicine and food in my country. Purslane contains a large amount of flavonoids and alkaloid compounds, which have antibacterial, blood lipid lowering, anti-aging, anti-inflammatory and other effects. At present, there are reports on the alcohol extraction of purslane, many of which focus on the...
