Embodiment 1

[0082]The preparation method of purslane fresh grass and or dry grass extract dry powder:

[0083] The picked fresh purslane grass is immersed in normal temperature (below 30°C) drinking water and rinsed until there is no soil and other impurities. Remove and drain.

[0084] 500kg of fresh purslane grass that has been cleaned is pulverized by a colloid mill to form a slurry. Add 250L of pure water to the slurry, stir, heat up to 45°C, add 0.5L of compound plant hydrolase (produced by Novozymes), and keep it warm for 3 hours for enzymolysis.

[0085] After the heat preservation enzymatic hydrolysis is completed, 60% ethanol is added to the feed liquid to adjust the final ethanol content in the feed liquid to 40%. Slowly heat the extract to 50°C under stirring, heat-preserve and stir for extraction for 1 hour, and when the heat-preserve extraction is completed, the feed liquid is filtered to obtain filtrate A, which is to be concentrated and dealcoholized.

[0086] Add 1800L ...

Embodiment 2

[0098] The preparation method of purslane fresh grass and or dry grass extract solution:

[0099] The fresh herb of purslane preserved in cold storage is soaked in normal temperature (below 30°C) drinking water and rinsed until there is no soil and other impurities. Remove and drain.

[0100] 500kg of fresh purslane grass that has been cleaned is pulverized by a colloid mill to form a slurry. Add 250L of pure water to the slurry, stir, heat up to 55°C, add 1.0L of cellulase (produced by Shandong Anke Bioengineering Co., Ltd.), and incubate for 1 hour for enzymolysis.

[0101] After the heat preservation enzymolysis is completed, 70% ethanol is added to the feed solution to adjust the ethanol content in the final feed solution to 50%. Slowly heat the extract to 60°C under stirring, keep stirring and extract for 2 hours, and when the heat preservation extraction is completed, filter the feed liquid to obtain filtrate A, which is to be concentrated and dealcoholized.

Embodiment 3

[0115] The preparation method of purslane fresh grass and or dry grass extract dry powder:

[0116] Purslane hay removes dirt and other impurities. Take 400kg of clean purslane hay, add 800L of pure water to it, stir, heat up to 30°C, add 0.8L of compound plant hydrolase (produced by Novozymes) to it, and keep it warm for 3h.

[0117] After the heat preservation enzymolysis is completed, 80% ethanol is added to the feed solution to adjust the ethanol content in the final feed solution to 60%. Slowly heat the extract to 70°C under stirring, keep stirring and extract for 1.5 hours, and when the heat preservation extraction is completed, filter the feed liquid to obtain filtrate A, which is to be concentrated and dealcoholized.

[0118] Add 2400L of 60% ethanol aqueous solution by volume to the reversing filter residue, stir, and slowly heat the extract to 70°C under stirring, keep stirring and extract for 1.5h, after the heat preservation extraction is completed, filter the fee...

Abstract

The invention discloses a herba portulacae extract and a preparation method thereof. The preparation method comprises the following steps of: 1, carrying out extraction and enzymolysis on fresh herba portulacae and/or dried herba portulacae with water and hydrolysis enzyme; 2, carrying out ethanol extraction on a feed solution obtained in the step 1, carrying out solid and liquid separation to obtain an extraction solution A and filter residue; 3, carrying out ethanol extraction on the filter residue obtained in the step 2, carrying out solid and liquid separation to obtain an extraction solution B and filter residue; 4, extracting the filter residue obtained the step 3 by using water, carrying out solid and liquid separation to obtain an extraction solution C; and 5, mixing the extraction solutions A, B and C obtained the step 2, 3 and 4, removing ethanol, concentrating, standing, and filtering to obtain filtrate to obtain the herba portulacae extract. The invention also discloses the herba portulacae extract solution and the preparation method thereof. A herba portulacae extract or extract solution can be used as an anti-stimulation and antianaphylaxis function component to be applied to cosmetics. The preparation method disclosed by the invention can be used for preparing the herba portulacae extract with higher effective component content, with high yield.

Description

technical field [0001] The present invention specifically relates to purslane extract, solution, preparation method and application thereof. Background technique [0002] Some ingredients used in cosmetics and personal care products such as surfactants, fragrances, preservatives and some functional ingredients can be irritating, especially to people with "sensitive skin". [0003] For example, the surfactant sodium lauryl sulfate, used as a surfactant in cosmetic formulations, can occasionally cause skin irritation at certain concentrations. [0004] Another example is glycolic acid, which is a kind of fruit acid. When used in cosmetics, it can soften the viscous lipids on the surface of the skin epidermis to facilitate the removal of old cutin, accelerate cell regeneration, reduce skin wrinkles and scars, and increase Skin luster, whitening and other beneficial effects. However, high concentrations of glycolic acid are irritating to a certain extent and can occasionally c...
