Abstract

The present invention relates to emblic extract and its preparation process and application. Dried emblic powder is first microwave assisted solvent extracted, and the emblic extract is then extracted with diethyl ether and ethyl acetate and macroporous resin purified to obtain purified emblic extract. The purified emblic extract is one kind of natural antioxidant with emblic polyphenol in the content over 93 % as the main effective component. The emblic extract as natural antioxidant is superior to available synthetic antioxidants, and has high DPPH free radical eliminating activity, high lipid peroxide inhibiting activity and high peroxidation resisting capacity.

Description

technical field [0001] The present invention relates to the extraction technology of Amaryllis Radix, in particular to the extract of Amaryllis Radix, a preparation method and application thereof. technical background [0002] Oxidation of oils and fats in food will lead to rancidity and deterioration of products, which not only reduces the nutritional value of food, but also has toxic and side effects in some oxidation products, posing a great threat to human health. Therefore, how to reduce the oxidation of oil is an important topic in the field of food and medicine, and the most commonly used method to prevent the oxidative rancidity of oil is to add antioxidants. [0003] Existing antioxidants are mainly synthetic antioxidants, such as propyl gallate (PG), butylated hydroxyanisole (BHA) and dibutylhydroxytoluene (BHT), etc. Although the effect is remarkable, there are some safety problems. , Livestock and poultry have certain toxicity to the body after ingestion, and an...
