Problems solved by technology

However, there is no method to obtain non-epicatechin directly from green tea leaves with high yield and purity, and even if it is possible to obtain non-epicatechin directly from green tea leaves, it can only be obtained in a very small amount at the laboratory level

Embodiment Construction

[0024] Hereinafter, embodiments of the present invention will be described in detail so that those of ordinary skill in the art to which the present invention pertains can easily implement the present invention. However, the present invention can be implemented in various ways, and is not limited to the embodiments described below.

[0025] In this specification, when it is described that a layer, film, region, plate, etc. is partly located "on another part", this includes not only a case where another part is "directly above" but also a case where other parts exist in between. Also, when a part is described as being "directly on" another part, there are no intervening parts.

[0026] In the specification, unless otherwise defined, "combining" means mixing or copolymerizing. In addition, "copolymerization" means block copolymerization or random copolymerization, and "copolymer" means block copolymer or random copolymer.

[0027] In the specification, unless otherwise defined...

Abstract

The invention provides a method of obtaining Non-epicatechin and Non-epicatechin using the same. The method includes the steps: putting green tea leaves into a container; and after sealing the container, circulating air in the container to increase the temperature of the air, and placing the green tea leaves at a temperature above 160 DEG C for 5 minutes to 30 minutes.

Description

technical field [0001] The invention relates to a method for obtaining non-epicatechin and the non-epicatechin obtained by the method. Background technique [0002] There are roughly eight components in tea catechins in nature, and 10% to 15% of the total dry weight of green tea is tea catechin content, of which epigallocatechin gallate (EGCG) accounts for 50% to 60% . Gallocatechin gallate (GCG), the 2-carbon isomer of epigallocatechin gallate, is a low-content catechin, accounting for only 0.8% to 1.5% of the catechin content in green tea. [0003] Typical catechins in green tea are epicatechin [(-)EC], epigallocatechin [(-)EGC], epicatechin gallate [(-)ECG], and epigallocatechin Gallate [(-)EGCG], from the currently reported antioxidant effect of green tea to reducing cholesterol absorption, inhibiting the rise of neutral fat, antibacterial, anti-tumor, anti-cancer, skin beauty, curbing obesity, inhibiting mutagenicity, etc. activity of these catechins. It was recentl...
