Embodiment

[0093]

[0094] 10 ml of a 2% phosphoric acid solution was added to 250 mg of Hongfugui tea powder (moisture content: 3%) whose water content had been measured in advance to obtain a tea dispersion. Next, 10 ml of ethanol was added to the tea leaf dispersion, stirred, and then kept at 30° C. for 60 minutes. Next, after constant volume with distilled water, it was stirred, left to stand for about 5 minutes, and then filtered. Additionally, 10 ml of the filtrate was collected into a 15 ml Falcon tube. This filtrate was filtered with a 0.45 μm hydrophilic filter (ADVANTEC: DISMIC-13HP, PTFE non-sterile), and collected into a 1.5 ml Eppendorf tube. Then, the supernatant was diluted 10-fold with distilled water (900 μl of distilled water and 100 μl of supernatant in a 1.5 ml Eppendorf tube). Next, collect about 100 μl of it into an autoinjector tube, and extract ECG3"Me under the following conditions as the antiallergic drug involved in the present invention.

Abstract

The object is to isolate a substance having a potent anti-allergic effect inherent in a tea leaf of an Assam hybrid line. Thus, disclosed is an anti-allergic agent comprising, as an active ingredient, a catechin yielded by the isolation separation, i.e., epicatechin-3-O-(3-O-methyl)gallate, epicatechin-3-O-(4-O- methyl)gallate, epicatechin-3-O-(3,4-O-dimethyl)gallate, epicatechin-3-O-(3,5-O-dimethyl)gallate, epicatechin-3-O- (3,4,5-O- tromethyl)gallate, an epimer thereof or the like. Also disclosed is a beverage/food, a preparation for external application or a cosmetic comprising the anti-allergic agent. An anti-allergic composition can be prepared using a compound represented by the general formula (1): (1) wherein R1, R2 and R3 independently represent a hydrogen atom or a methyl group.

Description

technical field [0001] The present invention relates to an antiallergic drug containing novel catechin as an active ingredient, and food, drink, external medicine, and cosmetics containing the same. Background technique [0002] In modern society, with the diversification of eating habits and lifestyles, allergies tend to diversify and increase year by year. Currently, there are 30 million allergy sufferers including potential sufferers. In addition, many people are worried about the side effects of drugs such as steroids. Although they are aware of allergic symptoms, they are worried about the side effects of drugs, so they cannot expect active treatment and suffer from symptoms. Therefore, the development of foods and beverages that can easily and safely ingest ingredients having antiallergic effects is highly expected and interested by consumers. [0003] It has been pointed out in the prior art that catechins, saponins, flavonoids, and caffeine contained in green tea h...
