Description

  The present invention relates to a proanthocyanidin trimer derived from peanuts, a method for producing the same, and use thereof.

  Proanthocyanidins, known as higher plant biodefense substances, are generally dimers or more polymerized by a binding mode such as 4β → 6, 4β → 8, 4β → 8 · 2βO → 7 with flavan-7-ol as a constituent unit. And is also called condensed tannin (Non-Patent Document 1 and Non-Patent Document 2). These are collectively called proanthocyanidins because they produce anthocyanidins by acid treatment and turn red. Proanthocyanidins are known to exhibit various physiological activities, including antitumor, anti-inflammatory, anti-aging, antioxidant, anti-allergic, antibacterial, hyaluronidase activity inhibition, hair growth, skin whitening, skin aging Activities such as prevention and Maillard reaction inhibition have been reported (Non-Patent Document 3, Non-Patent Document 4, and Patent Documents 1 to 5). The structure-activity relationship between these physiological activities and the degree of polymerization of proanthocyanidins is not completely clarified. For example, for hair-growth activity, 2 to 5 mer of proanthocyanidins (particularly dimer). And trimeric) proanthocyanidin oligomers have been reported to have the highest activity (Patent Document 6).

  With regard to separation and purification of proanthocyanidins from plants, conventionally, separation from various plant bodies such as grape seeds, pine bark, ginkgo biloba, peanuts and cacao beans has been attempted. Among these, examples of industrial extraction from raw materials include extraction from grape seeds (Patent Documents 7 to 9) or pine bark (Patent Documents 10 and 11). In the method described in Patent Document 7, white grape seeds are contacted with water of less than 70 ° C. and pretreated, and then subjected to hot water extraction. The obtained extract is passed through a Sephadex LH-20 column. After towering, it is eluted with 70% ethanol to obtain a proanthocyanidin-containing powder having a purity of about 90%. In the method described in Patent Document 10, the coastal pine bark 1t is subjected to hot water extraction in a pressurized state, and elution with ethyl acetate and precipitation by addition of chloroform are repeated to obtain a proanthocyanidin-containing powder.

From peanut seed coat:

(3) An anti-inflammatory agent comprising the proanthocyanidin trimer according to (1).
(4) Foods containing the proanthocyanidin trimer according to (1).
(5) A cosmetic containing the proanthocyanidin trimer according to (1).
(6) The method for producing a proanthocyanidin trimer according to the above (1), comprising extracting with water without separating the seed coat from the seeds of peanuts, and purifying the obtained extract.

  ADVANTAGE OF THE INVENTION According to this invention, the peanut origin proanthocyanidin trimer, its manufacturing method, and a use can be provided.

  The peanut fruit has a strong pericarp and usually contains two seeds inside. Indigenous seeds have a seed coat that wraps them. In order to obtain the proanthocyanidin trimer of the present invention, extraction with water is preferably performed without separating seed coats from peanut seeds. Thereby, proanthocyanidins can be obtained efficiently and with high purity. As the peanut seed, it is preferable from the viewpoint of the purity of the obtained proanthocyanidins to exclude and use the seed coat whose seed coat covers the whole seed, excluding the seed coat that has been peeled off entirely or partially.

Conventionally, seed coats separated from peanut seeds have been used for the preparation of peanut seed coat extracts. In this case, proanthocyanidins are modified or removed during the drying process and the separation process during seed coat separation. The yield and purity are reduced, and further, when separating the seed coat from the seed, the oil component derived from the seed adheres to the seed coat, the oil component is mixed into the extract, and the purity is reduced.
When the seeds are washed before extraction, it is preferable from the viewpoint of the yield of proanthocyanidins that the seeds are washed easily with water or the like to remove the dirt.

The types of water used for extraction are drinking water, skin, natural water, RO (reverse osmosis membrane) treated water, deep layer water, magnetized water, monomolecular water, treated water with different water binding angles, etc. Anything may be used as long as it is applicable to the above.
Usually, 1-5 L of water per 1 kg of seed is used.

The extraction temperature is preferably 5 to 50 ° C, more preferably 10 to 30 ° C. Supercritical extraction may be performed. The extraction is usually performed under normal pressure, but may be performed under pressure or under reduced pressure. The extraction time varies depending on the extraction temperature and the like, and is usually 5 minutes to 1 day, but is preferably within a time during which seed-derived oil does not elute. When extracting at 5-50 degreeC, extraction time becomes like this. Preferably it is 5-60 minutes, More preferably, it is 10-30 minutes.
Untreated peanut seeds may be added to the extract again, and the same extraction operation as described above may be repeated one or more times.

  The target extract can be obtained by filtering the extract obtained as described above with a cloth, stainless steel filter, filter paper or the like to remove peanut seeds, impurities, and the like.

  The structural formula of compound 1 (proanthocyanidin trimer: epicatechin- (2β → O → 7,4β → 6)-[epicatechin- (4β → 6)]-epicatechin) is shown below.

  None of the proanthocyanidin trimers were hit in the SciFinder search, and were judged to be new substances not described in the literature.

(Example 2) Inhibitory effect on the production of inflammatory cytokines (TNF-α, IL-6) in THP-1 cells For compound 1 (proanthocyanidin trimer), THP-1 cells of human monocytic leukemia cell line The immunostimulatory effect was evaluated. That is, it is produced when lipoprotein (LPS), which is an endotoxin of E. coli-derived toxin, is stimulated (100 ng / ml) or unstimulated by causing compound 1 to act on cultured THP-1 cells reflecting the monocyte-based immune response in humans. The concentration of inflammatory cytokines (TNF-α, IL-6) was evaluated by ELISA. LPS binds to the CD14 receptor of monocyte cells and induces cytokine production via MAP kinase. IL-6 is produced through the same transcription factor as TNF-α, but post-production cellular actions induce NF-κB in TNF-α and NF-IL-6 in IL-6, TNF-α acts in inflammation and cutaneous tissue turnover in the inflammatory process, and IL-6 is involved in the chronogenic and turnover processes of the inflammatory response, respectively. Therefore, by measuring these factors simultaneously, it is possible to know the effects on different control mechanisms for skin inflammation.

  Compound 1 significantly suppressed the production of inflammatory cytokines TNF-α and IL-6 in THP-1 cells under LPS stimulation. This suggests the anti-inflammatory action of Compound 1 (proanthocyanidin trimer) at the cellular level.

(Experimental method and results)
Using a RPMI-1640 basal medium supplemented with 5% bovine serum (FBS), a human monocytic leukemia cell line (THP-1) purchased from SIGMA was cultured at 37 ° C. in the presence of 5% CO ₂ .

THP-1 cultured cells were mixed with RPMI-1640 medium containing 5% FBS at a ratio of 1.5 × 10 ⁵ cells / well, and 970 μl of the cell suspension was added to a 24-well petri dish, and 5% CO _{2 was} present. Pre-cultured for 4 hours at 37 ° C. in the lower incubator.

Samples were dissolved in DMSO solution and diluted in basal medium to a final concentration of 0.1-20 μg / ml. The final concentration of DMSO was mixed to 0.3%.
To the cells cultured for 4 hours, 20 μl of the prepared sample solution and 10 μl of lipopolysaccharide (LPS) so that the final concentration was 0.1 μg / ml were administered and cultured for 36 hours.

After culturing for 36 hours, one per well from a 24-well petri dish was collected in an Eppendorf tube, centrifuged at 2000 rpm, 0 ° C. for 5 minutes, and the supernatant and 200 μl of each were added to the 96-well petri dish, Temporarily stored at -80 ° C. The amount of cytokine (TNF-α, IL-6) contained was measured by ELISA.
The results are shown in Table 2.
