Problems solved by technology

When plant raw materials are used as research materials, most of them need to extract oil first, filter and concentrate, and then perform saponification and extraction. This traditional manual operation has many steps, is cumbersome and time-consuming.
Especially when the raw material contains chlorophyll, the processing is more cumbersome

preparation example Construction

[0025] The invention provides a preparation method of ginseng flower extract, and its steps and conditions are as follows:

[0026] Step 1: Process the dried ginseng flowers into powder, add petroleum ether, and extract by the reflux method. The extraction time is preferably 0.5-2h. After the extraction, the petroleum ether solution is poured out; the volume of the petroleum ether is V 1 (ml): Mass M of dried ginseng flower powder 1 (gram) is preferably (6-50): 1;

[0027]Step 2: add potassium hydroxide, n-hexane, methyl tert-butyl ether, acetonitrile and water to the petroleum ether solution in step 1, and stir and heat; the heating temperature is preferably 90-300 ° C, and the heating time is preferably 0.5-2h, the stirring speed is preferably 100-300rpm; the volume V of the original petroleum ether 1 (mL): volume V of n-hexane 2 (mL): volume V of methyl tert-butyl ether 3 (mL): volume V of acetonitrile 4 (ml): volume of water V 5 (mL): Mass M of Potassium Hydroxide 2...

Embodiment 1

[0032] Process the dried ginseng flower into powder, weigh 5g, add 100mL petroleum ether, extract by reflux method, extract for 0.5 hour, filter after the extraction, the volume of petroleum ether extract is 91mL, take the 91mL petroleum ether solution, add 2g hydrogen Potassium oxide, 80 mL of n-hexane, 80 mL of methyl tert-butyl ether, 100 mL of acetonitrile and 100 mL of water were heated with stirring at a temperature of 100° C., the heating time was 0.5 hour, the stirring speed was 100 rpm, and after the heating was completed, let stand for 60 min, and take The petroleum ether layer was concentrated under reduced pressure to obtain ginseng flower extract.

[0033] The relative contents of Stigmasterol (stigmasterol), γ-Sitosterol (γ-sitosterol), Stigmast-7-en-3-ol, (3β, 5α)- were determined by gas chromatography and mass spectrometry. Gas chromatograph and mass spectrometer: American Thermo-Scientific ITQ900.

Abstract

The invention provides a preparation method of ginseng flower extract, which belongs to the field of preparation of oil unsaponifiable matter. In this method, dried ginseng flowers are processed into powder, petroleum ether is added, extracted by reflux, and petroleum ether solution is poured out after extraction; potassium hydroxide, n-hexane, methyl tert-butyl ether, acetonitrile are added to the petroleum ether solution and water, stirring and heating; after heating, let it stand still, take the uppermost layer, that is, the petroleum ether layer, and concentrate under reduced pressure or normal pressure to obtain the ginseng flower extract. It is proved by gas chromatography and mass spectrometry that the unsaponifiable matter sample in ginseng flower oil obtained by the preparation method contains 6 chromatographic peaks, of which 3 chromatographic peaks have relatively large peak areas, and the three chromatographic peaks are respectively Stigmasterol, γ ‑Sitosterol, Stigmast‑7‑en‑3‑ol, (3β,5α)‑, these three substances accounted for more than 93% of the total unsaponifiable matter by normalization method.

Description

technical field [0001] The invention belongs to the field of preparation of oil unsaponifiable matter, and in particular relates to a preparation method of a ginseng flower extract. Background technique [0002] Ginseng flower is the dried inflorescence of Panax ginseng C.A.Mey. Wild distributed in northern Hebei, Liaoning, Jilin, Heilongjiang, now widely cultivated in Liaoning, Jilin, Beijing, Hebei, Shanxi are also introduced and cultivated. Harvest the inflorescences from June to July and dry them. It has the effect of invigorating Qi and strengthening the body and delaying aging. Commonly used for dizziness, fatigue, chest tightness and shortness of breath. Ginseng flowers mainly contain saponins, chlorophyll, volatile oils and fatty oils. Modern medicine believes that ginseng flower has anti-inflammatory, antibacterial, anti-fatigue and anti-tumor effects. In addition to saponins, volatile oils and fatty oils are an important class of chemical components in ginseng...
