Problems solved by technology

[0011] However, seeds are also listed as examples of plants of the family Canaceae, but there is only a description centering on the fact that the use of roots as plant parts is suitable, and there is no description that active use of seeds is suitable. Record of center contents
Moreover, there is no record of any antibacterial effect (bacteriostatic effect) on bacteria, yeast or mold related to food spoilage or secondary pollution
[0012] On the other hand, obtaining the extract (high-content extract) from the root of the plant means that the plant itself is removed, and it is difficult to ensure the quantity. In addition, compared with the case of collecting seeds, it is labor-intensive and efficient at the time of collection. low, and damage the plant body, which may weaken its vitality

Embodiment I-1

[0064] Take 100 g of the thin slices of the fruit of the stalks and vines, add 1 kg of methanol therein, heat and reflux for 3 hours, and then filter. The filtrate was concentrated and dried under reduced pressure to obtain 3.2 g of glutinous rice extract.

[0065] When measuring the absorption spectrum of the 50% ethanol solution of this Xianmaimateng extract, it shows that there is a maximum absorption at 315nm, and when carrying out thin-layer chromatography (silica gel TLC; Developing agent: chloroform / methanol=4 / 1), R f Spots are shown at a value of 0.45.

Embodiment I-2

[0067] Add 334 g of the thin slices of Mateng vine seeds into 900 g of 50% ethanol, soak at room temperature for 2 days, and then filter. After the filtrate was concentrated under reduced pressure and the ethanol was evaporated, the concentrated solution was freeze-dried to obtain 22.5 g of a solid (powder) Xianmaimateng extract. Analyze with the same method as embodiment 1, show maximum absorption at 320nm, R f A value of 0.50 shows spots.

Embodiment I-3

[0069] Add 246 g of crushed Matachi seeds into 30 kg of 30% ethanol, soak at about 50° C. for 3 hours, and filter. After the filtrate was concentrated under reduced pressure and the ethanol was evaporated, 25 g of fatty acid esters of glycerol and 50 g of pepper essence were dissolved in the concentrated solution, and then spray-dried to obtain 101.1 g of powdered Xianmaimateng extract. Analyze with the same method as embodiment 1, show maximum absorption at 325nm, R f A value of 0.55 shows spots.

Abstract

A Gnetum extract having antibacterial activity and antioxidant activity (radical scavenging activity), obtained from Gnetum fruit or Gnetum seed without the need to conduct any special operation. This Gnetum extract exerts various physiological (pharmacological) activities and hence can be used as an active ingredient of food, aliment (nutritional supplement), medicine, cosmetic, etc. The Gnetum extract can be obtained by immersing slices or triturates of Gnetum fruit or Gnetum seed in water or a water-containing organic solvent and performing ripening thereof.

Description

technical field [0001] The present invention relates to a high-concentration liquid or powder (hereinafter referred to as "Mai Ma Teng extract") containing a new extract obtained from the fruit (seed and / or pericarp) of Ma Ma Teng. [0002] Furthermore, it is possible to expect the use of the Mateng extract of the present invention as a material for foods, seasonings, nourishing agents, pharmaceuticals, cosmetics, and the like. [0003] Buy Mateng extract, which has the antioxidant effect of inhibiting lipid oxidation in food and protecting organisms from oxidative damage, tyrosinase inhibition, cyclooxygenase inhibition, lipoxygenase inhibition, acetylcholinesterase inhibition Function, protein kinase C inhibition, topoisomerase II inhibition, ultraviolet defense, whitening, anti-inflammation, immune regulation, hair care, and odor caused by the proliferation of harmful microorganisms, excellent antibacterial and deodorant Smell effect. [0004] In addition, in the followin...
