Embodiment 1

[0057] 1. A method for extracting active ingredients from the dried leaves or dried flowers of the plant Golden Camellia, the process is as follows:

[0058] 1) First prepare alkaline small molecule water for later use; the pH of the alkaline small molecule is 9-10;

[0059] 2) Collect golden camellia leaves and flowers, remove sundries, and set aside;

[0060] 3) Grinding the dried golden camellia leaves and dried flowers with a grinder;

[0061] 4) Use alkaline small molecule water with a pH of 9-10 and put them into the broken golden camellia leaves or flowers respectively, add 8-10 liters of alkaline small molecule water per kilogram of golden camellia leaves or flowers; the soaking temperature is 1 -10°C for 3-5 hours, then extract for the first time at 10-20°C for 3-5 hours to separate the extract and slag; the extract of Camellia japonica leaves or flowers is stored separately;

[0062]5) Put the alkaline small molecule water with pH 9-10 into the slag respectively; a...

Abstract

The invention discloses a method for extracting effective constituents from dry leaves or dry flowers of the precious plant camellia nitidissima C. W. Chi. Camellia nitidissima C. W. Chi flower and leaf extracts prepared with modern bioengineering techniques including micro cluster water efficient extraction and membrane engineering molecular retention are rich in polyphenol, flavone and other antioxidant ingredients and antisepsis and anti-inflammation ingredients, extraction and separation yield is high, and the extracts can be used for preparing drugs, food and drink.

Description

technical field [0001] The invention relates to a method for extracting active ingredients from plants, in particular to a method for extracting active ingredients from the dried leaves or dried flowers of the precious plant Camellia camellia and its use in preparing health care products. Background technique [0002] Camellia, Latin scientific name ( Camellia nitidissima C. W. Chi ); Golden Camellia belongs to the family Theaceae and Camellia genus, and was first discovered in my country in 1960; Camellia Camellia is an ancient plant, extremely rare, and its distribution is extremely narrow. 90% of the wild Camellia camellia in the world is only distributed in Fangchenggang, Guangxi Zhuang Autonomous Region, China It grows in the Lanshan branch of the Shiwanda Mountain in the city below 700 meters above sea level. It is also found in Nanning, Qinzhou City, and Vietnam in Guangxi, but the number is very small; Camellia japonica blooms in golden yellow, dazzling, as if coated ...
