Embodiment 1

[0042] The preparation method of anti-aging black ginger extract comprises the following steps:

[0043] Step 1: Using black ginger rhizomes as raw materials, put the black ginger rhizomes in liquid nitrogen and keep them frozen for 10 minutes; take out the frozen black ginger rhizomes, crush them into powder with a powder machine, and pass through an 80-mesh sieve to obtain black ginger powder ;

[0044] Step 2: Weigh black ginger powder, add ethyl acetate according to the ratio of solid to liquid 1:10 (g / mL), reflux and extract at 90°C for 8 hours, collect the extract; add an equal volume of water to the extract and extract for 1 hour , separate the ethyl acetate phase of the upper layer and the water phase of the lower layer; dry the ethyl acetate phase of the upper layer under reduced pressure at 50° C. and an absolute pressure of 0.03 MPa to remove ethyl acetate, and then vacuum freeze-dry to obtain the anti-aging Black Ginger Extract.

Abstract

The invention discloses an anti-aging black ginger extract and a preparation method thereof. The preparation method of the anti-aging black ginger extract comprises the steps that: an effective part of a black ginger is used as a raw material, the effective part of the black ginger is subjected to liquid nitrogen refrigeration, and then the effective part of the black ginger is crushed into powderto obtain black ginger powder; then the black ginger powder is used for extracting to obtain the anti-aging black ginger extract. The anti-aging black ginger extract obtained by the invention is a well-loved long-lived food material, can prevent the production of glycosylation products by inhibiting protein non-enzymatic saccharification reaction, thereby reducing the incidence of age-related chronic diseases and protein aging. In addition, the anti-aging black ginger extract also has a significant improvement effect on learning and memory disorders, enhances brain free radical scavenging ability, and improves the degeneration and shedding of hippocampal neurons.

Description

technical field [0001] The invention relates to the technical field of biological products, in particular to an anti-aging black ginger extract and a preparation method thereof. Background technique [0002] Black ginger, scientific name Kaempferia parviflora Wall.Ex Braker, belongs to Zingiberaceae, also known as black tulip in Japan. Black ginger is grown or cultivated mainly in Southeast Asia because it can be easily obtained. In Thailand, black ginger is regarded as a kind of traditional herbal medicine, and it is a traditional ingredient that has been eaten daily in the local area since ancient times. In the local folk, black ginger is used to nourish and strengthen, enhance energy, lower blood sugar, restore physical strength, improve circulation, and improve indigestion, etc. [0003] Zingiberaceae plants are mainly divided into three types: Zingiber officinale, Curcuma longa and Black ginger. The main special ingredient of ginger plants is ginger oil, which improv...
