Embodiment 1

[0027] A process for extracting the active ingredient from Trichosanthes rind, comprising the following steps:

[0028] (1) Cleaning: Soak Trichosanthes rind in the mixed solution of magnesium sulfate of 6% mass concentration and molybdenum nitrate of 30% mass concentration for 20min, then rinse with water, dry with air cooler, pulverize, pass through a 30-mesh sieve, and obtain Trichosanthes skin powder;

[0029] (2) Freezing: Soak the Trichosanthes husk powder with water until the water content is 16%. The soaked Trichosanthes husk powder is frozen at -10°C for 4 hours, then thawed in water at 5°C, and put into a drying box after thawing Warm up to 70°C and keep warm for 10h;

[0030] (3) extracting polysaccharides: add Trichosanthes husk powder to powder quality 8% cellulase, 3% citric acid, 2% tert-butyl hydroquinone, 2% diallyl isophthalate and mix Uniform, add acetic acid to the mixture to adjust the pH to 6, enzymatic hydrolysis reaction at 28°C for 6h, after the reac...

Embodiment 2

[0033] A process for extracting the active ingredient from Trichosanthes rind, comprising the following steps:

[0034] (1) Cleaning: Soak Trichosanthes rind in the mixed solution of magnesium sulfate of 7% mass concentration and molybdenum nitrate of 25% mass concentration for 30min, then rinse with water, dry with air cooler, pulverize, and pass through a 30-mesh sieve to obtain Trichosanthes skin powder;

[0035] (2) Freezing: soak the Trichosanthes husk powder with water until the water content is 17%, freeze the soaked Trichosanthes quinces skin powder at -10°C for 3 hours, then thaw it in water at 10°C, and put it in a drying box after thawing Warm up to 65°C and keep warm for 11 hours;

[0036](3) extracting polysaccharides: add Trichosanthes husk powder to powder mass 7% cellulase, 4% citric acid, 1% tert-butyl hydroquinone, 1% diallyl isophthalate and mix Evenly, add acetic acid to the mixture to adjust the pH to 6, enzymolysis reaction at 30°C for 5 hours, after th...

Embodiment 3

[0045] A process for extracting the active ingredient from Trichosanthes rind, comprising the following steps:

[0046] (1) Cleaning: Soak Trichosanthes rind in the mixed solution of magnesium sulfate of 8% mass concentration and molybdenum nitrate of 30% mass concentration for 25min, then rinse with water, dry with air cooler, pulverize, and pass through a 30-mesh sieve to obtain Trichosanthes skin powder;

[0047] (2) Spread the melon skin powder into a thin layer of 1.5cm thick, first place the thin layer at 90°C and 0.07Mpa saturated vapor pressure for 30 minutes, and then transfer it to 120°C and 2Mpa high temperature and high pressure environment for standing 20min, then quickly collect the thin layer and put it into 3°C water to cool, then put it into a drying oven and dry it completely at 80°C after cooling, add 3.2% active aluminum in the vacuum environment and mix evenly, and stir at 300r / min After 30 minutes, add 5% hydrochloric acid solution to the mixture, stop a...

Abstract

The invention discloses an extraction process for active ingredients of pericarpium trichosanthis, and relates to the technical field of pericarpium trichosanthis processing. The process includes thesteps of cleaning, freezing, extracting polysaccharides, extracting alkaloids and extracting triterpenoid saponins, cleaning process is carried out by using magnesium sulfate and molybdenum nitrate for cleaning, freezing is to freeze pericarpium trichosanthis powder at 10 DEG C for 3-4h, after thawing, cellulase, citric acid, tert-butyl hydroquinone and diallyl isophthalate extract polysaccharideare added, centrifuge sediment is added to acid and alkali-dissolving alkaloids and stored in liquid nitrogen, activated carbon is added for adsorption, and triterpenoid saponins is added to acidic extracts of celestial and sucrose for extraction; the process can be used for sequentially extracting polysaccharides, alkaloids and the triterpenoids, the extraction process is simple and easy to operate, the production efficiency is high, the yield of extracts is high, and the purity is high, thereby achieving the effective utilization of the value of the pericarpium trichosanthis.

Description

Technical field: [0001] The invention relates to the technical field of Trichosanthes peel processing, in particular to a process for extracting active components of Trichosanthes peel. Background technique: [0002] Gualou, aliases: Trichosanthes Lou, Tanggualou, Lougua. Trichosanthes kirilowii Maxim., a perennial climbing herb. Xi was born in the deep mountains and thorny cliffs. Its fruit, peel, kernel (seed), and rhizome are all good Chinese herbal medicines. Indications: clearing away heat and clearing phlegm, broadening the chest and dispelling stagnation, moistening dryness and smoothing the intestines.
