Anti-fatigue purposes and extraction method of antioxidant active ingredients of Chinese red pine needles

Abstract

The invention discloses anti-fatigue purposes of antioxidant active ingredients of Chinese red pine needles and a method for extracting the antioxidant active ingredients of Chinese red pine needles. The method for extracting the antioxidant active ingredients of Chinese red pine needles comprises the following steps: step 1, removing dead leaves and leaf stalks of fresh pine needles, flushing under running water, and airing in shade; step 2, shearing into small sections of 1cm by using ceramic scissors, grinding for 30 seconds by using an ultrafine grinder to obtain pine needle residues, and shading for later use; step 3, taking 10g of pine needle residues, and adding ultrapure water according to a material water ratio of 1 to (10-25) (g to ml); step 4, adding the mixture into a round-bottom flask, arranging the flask in Soxhlet extraction equipment, and leaching at the temperature of 70-100 DEG C for 60-150 minutes; and step 5, performing vacuum filtration on the leaching solution, thereby obtaining the filtrate containing the antioxidant active ingredients. The method has the beneficial effects that a novel natural antioxidant product is provided.

Description

technical field [0001] The invention belongs to the technical field of antioxidant compounds, and relates to an anti-fatigue application and an extraction method of an antioxidant active component of pine needles of masson pine. Background technique [0002] Pinus massoniana pine needles are needle-shaped leaves of Pinaceae plants. In recent years, studies have found that they are rich in natural antioxidant active substances such as flavonoids, lignans, vitamins, polysaccharides and trace elements, and are non-toxic and have no side effects. They can be used as Good source of natural antioxidants and antioxidant functional foods. [0003] At present, the research on the antioxidant activity of pine needles of masson pine mainly focuses on the extraction, separation and functional evaluation of components that may have some antioxidant activity. There is no report on the research of screening out active ingredients with antioxidant activity. Therefore, this study intends t...
