Abstract
The method for extracting carrotenoid and flavone compound from perilla leaf includes the following steps: naturally drying perilla leaf in dark or low-temperature stoving perilla leaf at 30-60 deg.C, pulverizing dried perilla leaf to 1-10 mm, adopting supercritical CO2 extraction, extraction temperature is 20-45 deg.c, extraction pressure is 10-40 MPa and extraction time is 1-5 h. to obtain oil-live extract and residue, said oil-like extract is extracted carrotenoid, then continuously using ethyl alcohol whose concentration is 40%-95% to extract dried residue or directly extract dried perilla leaf, solid-liquid ratio is 1:10-20, extraction temperature is 30-70 deg.C, extraction time is 1-5 h, extracting for 1-3 times, combining ethyl alcohol extracts, distalling to recover ethylalcohol to obtain paste-like extract, namely extracted flavone compound.
Description
Technical field
The present invention relates to from Perilla Leaf, extract the method for natural component carotenoid and flavonoid compound.
Background technology
Purple perilla is a Labiatae annual herb plant, at the cultivation history in existing more than 2000 year of China, it is traditional medicine food dual purpose plant, obtain development and use in industries such as food, medicine, chemical industry, especially be with the perilla seed in the perilla oil of feedstock production because of containing alpha-linolenic acid abundant, that help HUMAN HEALTH, and make purple perilla be planted in a large number, resource more than 20 province that spread all over the country.The results that are accompanied by purple perilla also have a large amount of Perilla Leafs, the past it be used as the inducing sweat medicinal material cold, relieving QI stagnancy in the stomach that looses always, but consumption is less.Also there is human greenhouse gardening purple perilla to win tender leaf, clean and cryodrying after export Korea S, Japan does vegetables or pickles are used, directly absorb carotenoid and flavonoid compound in the Perilla Leaf, but fresh and tender leaf price is expensive and output is little, the more important thing is that some natural nutrition compositions in the Perilla Leaf are not effectively utilized.
Summary of the invention
The purpose of this invention is to provide a kind of method of from Perilla Leaf, extracting carotenoid and flavonoid compound, by adopting supercritical CO
2Carotenoid and flavonoid compound natural components that extraction and alcohol solvent lixiviate are extracted respectively from Perilla Leaf, it is edible for people to make the convenient form of using such as capsule and drink.
The present invention be achieved in that will results Perilla Leaf dry in the shade naturally or under 30-60 ℃ temperature oven drying at low temperature, coarse crushing is adopted supercritical CO to 1-10mm
2Extraction, extraction temperature is 20-45 ℃, extracting pressure is 10-40Mpa, the extraction time is 1-5h, obtain oily extract and residue, wherein the oily extract is the carotenoid of extraction, continuing with concentration is that the ethanol of 40%-95% is to dried residue or directly dried Perilla Leaf is carried out lixiviate, solid-to-liquid ratio is 1: 10-20, extraction temperature is 30-70 ℃, and extraction time is 1-5h, lixiviate 1-3 time, merge alcohol extract, the flavonoid compound that the paste extract that obtains behind the ethanol is extraction is reclaimed in distillation.
Above-mentioned supercritical CO
2With the entrainment agent of perilla oil as extraction, the consumption of entrainment agent is by weight: Perilla Leaf: perilla oil=10-30: 1 (W/W) during extraction.
The present invention has that production technique is simple, the advantage of easy handling control, and the natural plant composition that is extracted can be made various medicines that are convenient for people to eat or food form, make purple perilla a large amount of by products---Perilla Leaf is effectively developed.
Description of drawings
Accompanying drawing is a process flow diagram of the present invention.
Embodiment
Further specify the present invention below in conjunction with drawings and Examples:
Embodiment 1: the Perilla Leaf of results is dried in the shade or oven dry under 30 ℃ naturally, and coarse crushing is adopted supercritical CO to 1mm
2Extraction, extraction temperature is 20 ℃, extracting pressure is 10Mpa, the extraction time is 5h, obtain oily extract and residue, wherein the oily extract is the carotenoid (content is 300mg/kg) of extraction, continuing with concentration is that 40% ethanol is to dried residue or directly dried Perilla Leaf is carried out lixiviate, solid-to-liquid ratio is 1: 10, extraction temperature is 30 ℃, and extraction time is 5h, lixiviate 3 times, merge alcohol extract, the flavonoid compound (content is 40mg/g) that the paste extract that obtains behind the ethanol is extraction is reclaimed in distillation.
Embodiment 2: is 60 ℃ of following oven drying at low temperatures with the Perilla Leaf of results in temperature, and coarse crushing is adopted supercritical CO to 10mm
2Extraction, and with perilla oil as the extraction entrainment agent, its consumption is by weight: Perilla Leaf: perilla oil=30: 1 (W/W), extraction temperature is 45 ℃, extracting pressure is 40Mpa, the extraction time is 1h, obtain oily extract and residue, wherein the oily extract is the carotenoid (content is 1000mg/kg) of extraction, and continuing with concentration is that 95% ethanol is to dried residue or directly dried Perilla Leaf is carried out lixiviate, solid-to-liquid ratio is 1: 20, extraction temperature is 70 ℃, and extraction time is 1h, lixiviate 5 times, merge alcohol extract, the flavonoid compound (content is 10mg/g) that the paste extract that obtains behind the ethanol is extraction is reclaimed in distillation.
Resulting carotenoid of the foregoing description and flavonoid compound can be made the soft capsule that is beneficial to preservation and is convenient to eat respectively and have the nourishing beverage of Perilla Leaf peculiar taste.
Claims (2)
