Embodiment 1

[0024] Panax notoginseng volatile oil extraction

[0025] (1) Take fresh Panax notoginseng, remove the sediment, wash it, soak it in an aqueous solution containing 0.1-0.4wt% alum for 1-2 hours, and rinse it with clean water.

[0026] (2) Slice the notoginseng washed in step 1, add 30-60v% ethanol, heat to boiling and keep it for 0.5-3 hours, collect fractions, pay attention to supplement ethanol solution, and combine fractions.

[0027] (3) Extract the distillate from step 2 by adding petroleum ether, collect the petroleum ether phase, add anhydrous sodium sulfate for dehydration, and concentrate the petroleum ether phase under reduced pressure to obtain light yellow oil, which is Panax notoginseng volatile oil.

Embodiment 2

[0029] Panax notoginseng volatile oil extraction

[0030] (1) Take fresh Panax notoginseng, remove the sediment, wash it, soak it in an aqueous solution containing 0.2wt% alum for 2 hours, and rinse it with clean water.

[0031] (2) Slice the Panax notoginseng washed in step 1, add 40v% ethanol, heat to boiling and keep it for 2 hours, collect the fractions, pay attention to supplement the ethanol solution, and combine the fractions.

[0032] (3) Extract the distillate from step 2 by adding petroleum ether, collect the petroleum ether phase, add anhydrous sodium sulfate for dehydration, and concentrate the petroleum ether phase under reduced pressure to obtain light yellow oil, which is Panax notoginseng volatile oil.

Embodiment 3

[0034] Panax notoginseng volatile oil extraction

[0035] (1) Take fresh Panax notoginseng, remove the sediment, wash it, soak it in an aqueous solution containing 0.1wt% alum for 1 hour, and rinse it with clean water.

[0036] (2) Slice the Panax notoginseng washed in step 1, with a thickness of 2-5mm, add 30v% ethanol and heat to boil and keep for 3 hours, collect fractions, pay attention to supplement ethanol solution, and combine fractions.

[0037] (3) Add petroleum ether to extract the distillate in step 2, collect the petroleum ether phase, add 0.5wt% anhydrous sodium sulfate for dehydration, and concentrate the petroleum ether phase under reduced pressure to obtain light yellow oil, which is Panax notoginseng volatile oil.

Abstract

The invention discloses a pseudo-ginseng volatile oil extraction method. The pseudo-ginseng volatile oil extraction method comprises the following steps: (1) taking fresh pseudo-ginseng, removing silt, washing, soaking in an aqueous solution containing 0.1-0.4wt % of alum for 1-2 hours, and washing clean with clean water; (2) slicing the pseudo-ginseng obtained in the step (1), adding 30-60 v% of ethanol into the slices, heating to boil, keeping the temperature for 0.5-3 hours, collecting fractions, simultaneously paying attention to supplementing the ethanol solution, and merging fractions; (3) adding the fractions obtained in the step (2) into petroleum ether to extract the fractions, collecting the petroleum ether phase, adding anhydrous sodium sulfate for dehydration, and concentrating the petroleum ether phase under reduced pressure, so as to obtain faint yellow oil, namely the pseudo-ginseng volatile oil. According to the method for preparing the pseudo-ginseng volatile oil, the ethanol solution is used for heating and extracting, and the extracted pseudo-ginseng volatile oil has high extraction ratio, the obtained pseudo-ginseng volatile oil is good in purity due to extraction treatment, and the requirements of further research and application can be met.

Description

technical field [0001] The invention relates to a method for extracting and processing Chinese medicinal materials, in particular to a method for extracting and processing Radix Notoginseng, which belongs to the extraction and processing technology of volatile oil of traditional Chinese medicinal material Radix Notoginseng, and belongs to the field of biomedicine. Background technique [0002] Panax notoginseng is the dry root and rhizome of Panax notoginseng (Burk.) F.H.Chen of Araliaceae, mainly produced in Yunnan, Guizhou, Sichuan and other places. Radix Notoginseng is generally excavated before the flowers bloom in autumn, washed, separated from the main root, branch root and rhizome, and dried. [0003] Modern medical research mainly believes that Panax notoginseng contains a variety of ginsenosides and notoginseng saponins, so it has the effects of dispelling blood stasis, stopping bleeding, reducing swelling and relieving pain. Some studies have also found that Sanqi...
