Embodiment 1

[0024] Take 400kg of fresh perilla leaves (water content is 86%) and grind them with a grinder, add 800L of 85% ethanol aqueous solution immediately, adjust the pH value to 2.5 with 1mol / L hydrochloric acid solution, and carry out leaching at room temperature for 3h. Filtrate twice with three layers of gauze, filter once with a ceramic membrane to remove slag to obtain 750L filtrate I, then add 70kg of NKA-9 macroporous resin particles to the filtrate I and place it at room temperature for 40min, filter once with a ceramic membrane to obtain 110kg filter residue I and 700L filtrate II, The filtrate II was subjected to atmospheric distillation at 85°C to collect 3.5L perillaldehyde and recover ethanol. Perillaldehyde was rectified once again under normal pressure at 75°C to obtain 2.34kg of pure perillaldehyde. NKA-9 macroporous resin column particles were used for elution, and 4 times the volume of 70% ethanol aqueous solution with a pH value of 3 was used for elution, and the...

Embodiment 2

[0026] Take 1000kg of fresh perilla leaves (with a water content of 83%) and grind them with a grinder, immediately add 2500L of 80-90% ethanol aqueous solution, adjust the pH value to 2 with 1mol / L hydrochloric acid solution, and then extract at room temperature 3h. Filtrate twice with three layers of gauze, filter once with ceramic membrane to get 2400L filtrate I, then add 150kg of NKA-9 macroporous resin particles to filtrate I, leave it at room temperature for 30min, filter once with ceramic membrane to get 250kg filter residue I and 2300L filtrate II , The filtrate II was subjected to atmospheric distillation at 60°C to 85°C to collect 10.7L perillaldehyde and recover ethanol. Perillaldehyde was rectified once again under normal pressure at 70°C to obtain 5.86kg of pure perillaldehyde. NKA-9 macroporous resin column particles were used for elution, and 5 times the volume of 80% ethanol aqueous solution with a pH value of 2.5 was used for elution, and the eluate I was co...

Embodiment 3

[0028] Take 2000kg of fresh perilla leaves (with a water content of 84%) and grind them with a mincer, immediately add 3000L of 90% ethanol aqueous solution and 1mol / L hydrochloric acid solution to adjust the pH value to 2, and then carry out leaching at room temperature for 5 hours. Filtrate twice with three layers of gauze, filter once with ceramic membrane to get 2850L of filtrate I, then add 300kg of NKA-9 macroporous resin particles to filtrate I, leave it at room temperature for 20min, filter once with ceramic membrane to get 390kg of filter residue I and 2750L filtrate II , The filtrate II was subjected to atmospheric distillation at 60°C to 85°C to collect 19.6L perillaldehyde and recover ethanol. Perillaldehyde was rectified again under normal pressure at 70°C to obtain 11.42kg of pure perillaldehyde. NKA-9 macroporous resin column particles were used for elution, and 3 times the volume of 60% ethanol aqueous solution with a pH value of 2.5 was used for elution, and t...

Abstract

The invention belongs to the technical field of natural product extraction, and relates to a method for extracting perillaldehyde and anthocyanin from fresh folia perillae acutae.Pure perillaldehyde and anthocyanin are obtained through ethyl alcohol extraction, resin adsorption and normal-pressure rectificating.Folia perillae acutae has complicated components, and through combination of acid water extraction and distillation extraction, damage to anthocyanin can be avoided and the yield of perillaldehyde can be increased; through acid water extraction, the activity of enzyme in fresh folia perillae acutae can be effectively inhibited, and the stability of anthocyanin can be guaranteed during extraction.

Description

technical field [0001] The invention belongs to the technical field of natural product extraction, and relates to a method for extracting perillaldehyde and anthocyanin by using fresh perilla leaves. Background technique [0002] Perillaldehyde (Perillaldehyde, chemical name 4-isopropenylcyclohex-1-en-1-aldehyde), is a high-grade spice, widely used in tobacco, daily chemical, food and other industries, especially in the tobacco industry, can be obviously Improve the quality of cigarettes, reduce irritation, and make the aftertaste mellow and comfortable. Recently, a large number of studies have shown that the mixture of perillaldehyde and volatile oil has antibacterial, anticancer, anti-anisakis, antioxidant activity, and vasodilation effects. Perillaldehyde can react with hydroxylamine to prepare perilla scape. In addition, perillaldehyde has antibacterial, antiseptic and fresh-keeping effects, and is a newly developed natural fresh-keeping agent for plants. With the rap...
