Abstract

The invention belongs to tea processing field, discloses a kind of tealeaves volatile essential oil and preparing the application in cancer-preventing health product or anticancer drug.The cancer-preventing health product or anticancer drug refer to that prevention and treatment or treatment have the health care product or drug of the cancer of quinone reductase inductive effect.Tealeaves volatile essential oil is to be extracted using tealeaves as raw material by Simultaneous distillation.The tealeaves volatile essential oil of acquisition not only has the smell of pleasant, can releive anxiety, but also there is certain anticancer effect, 6 big teas include that the volatile essential oil concentration extracted of black tea, green tea, green tea, yellow tea, white tea and dark green tea can induce quinone reductase multiplication in the range of 3~30 μ g/ml and play antitumaous effect.Result of study shows that tealeaves volatile essential oil by inducing quinone reductase to play antitumaous effect, is a kind of potential anti-cancer active matter, can prepare cancer-preventing health product and anticancer drug.

Description

A kind of tealeaves volatile essential oil is preparing the application in cancer-preventing health product or anticancer drug
Technical field
The invention belongs to tealeaves intensive processing technical field, in particular to a kind of tealeaves volatile essential oil is protected in preparation anti-cancer Application in strong product or anticancer drug.
Background technique
Chinese tea drinking is with a long history, and Resources of Tea Plant is abundant, this provides advantageous condition for the person of drinking tea.Tea be most by One of the healthy beverage that people welcome, contains a variety of function such as tea albumen, tea polyphenols, tea polysaccharide, caffeine, tea saponin in tealeaves Ingredient is imitated, there are the physiological functions such as antitumor, hypoglycemic, reducing blood lipid, blood pressure lowering, anti-oxidant and enhancing immunity of organisms, as Health food and drug have wide development prospect.
Tea aroma substance classes are abundant, and content is atomic, typically constitutes from the 0.01~0.05% of dry matter of tea content, green Tea is about 0.005~0.02%, and black tea is about 0.01~0.03%, and oolong tea is about 0.05%.Tea aroma substance is by organic Chemical classification can be divided into hydrocarbon, alcohols, aldehydes, ketone, acids, esters, lactone, phenols, oxa- class compound, Sulfur-bearing class compound, containing nitrogen compound etc., wherein based on alcohols, ketone, esters, aldehydes and hydrocarbon.Fragrance contains Highest oolong tea is measured, fragrance is because of home environment, tea tree breed, fresh leaf, manufacture craft, quality grade, storage method Respective distinctive odor characteristic is shown Deng different, is affected especially with manufacture craft: attenuation degree less serious case, fragrance component Middle nerolidol, jasmine lactone, indoles equal size are higher;Attenuation degree severe one, linalool and its oxidation product, geraniol, benzene The component contents such as methanol are higher.In terms of tea comprehensive processing, Aqua Folium Camelliae sinensis extraction prepares instant tea, concentrated tea juice is processed for tea beverage It is used widely, the tea polyphenols separated in tealeaves include that catechin therein is widely used in food additives or production health care food Product, anticancer research even for field of medicaments such as anti-inflammatory drug and is done in part, but volatile essential oil, that is, aroma substance of tealeaves, protects Health-care function is paid attention to using seldom work in-process.There is patent using hydro carbons and its derivative (it is derivative to be originated from grease) to 6 big tea The volatile essential oil of class tealeaves has carried out the extraction of selectivity, prepares high fragrance after having patent to utilize correlation down enzymatic treatment tealeaves Tea extract, there are also patents, and microwave coupled ion liquid to be utilized to carry out the extraction of tea aroma and for analyzing.
Summary of the invention
In order to solve the disadvantage that the prior art and shortcoming, the purpose of the present invention is to provide a kind of tealeaves volatility essences Oil is preparing the application in cancer-preventing health product or anticancer drug.This method is simple, quickly.
The purpose of the present invention is achieved through the following technical solutions:
A kind of tealeaves volatile essential oil is preparing the application in cancer-preventing health product or anticancer drug.
The cancer-preventing health product or anticancer drug refer to that prevention and treatment or treatment have the cancer of quinone reductase (QR) inductive effect The health care product or drug of disease.
The tealeaves volatile essential oil is preferably extracted by Simultaneous distillation using tealeaves as raw material.? It can be prepared using other methods.
The Simultaneous distillation is specifically according to the following steps: tea raw material being ground, according to every gram of tealeaves original The ratio of material addition 5~20ml water adds water, obtains tea mixture;Using methylene chloride as extractant, using distilling simultaneously The methods of extraction equipment extracts, and extraction time is 60min~180min;Obtained solution is transferred to nitrogen in sample bottle to blow It is dry, obtain tealeaves essential oil.
Described to be extracted specifically according to the following steps using SDE method: tea mixture is placed in round bottom burning In bottle, it is connected to one end of distilling and extracting device, and heated with electric jacket, kept slightly boiled;The other end of distilling and extracting device connects Tipping has the round-bottomed flask of methylene chloride, is heated with water-bath, temperature is maintained at 55 DEG C.
When tealeaves dosage≤50 gram, the dosage of the methylene chloride is 50mL;When 50 grams of tealeaves dosage >, described two The dosage of chloromethanes is ml of tealeaves grams corresponding number.
The tealeaves is black tea, green tea, green tea, yellow tea, white tea and dark green tea.
The present invention induces its quinone reductase to by representative of murine hepatocarcinoma cell Hepa1c1c7 using tealeaves volatile essential oil (QR) activity rises to anticancer activity evaluation, and tealeaves volatile essential oil there is preferable inhibition to make Hepa1c1c7 cancer cell line With being a kind of potential cancer-resisting active material.
The present invention have the following advantages compared with prior art and the utility model has the advantages that
(1) present invention, which extracts obtained tealeaves volatile essential oil, has stronger cancer-preventing health and anticancer effect, and this hair Operation is simple for Simultaneous distillation involved in bright and correlation method, at low cost, and the rate of recovery of essential oil is high;Therefore, have Higher practical application and promotional value.
(2) the obtained tealeaves essential oil of the present invention can be applied in aromatotherapy, can not only relieving mood, eliminate burnt Consider, and also there is the health-care efficacy for inhibiting growth of cancer cells, have a good application prospect, can be applied to medicine, health care Product and daily use chemicals industry.
