Definitions
- the present invention relates to an anti-fatigue composition.
- the present invention also relates to a composition for improving, suppressing or maintaining energy producing ability.

- the present invention further relates to the use of one or more sesamin and lutein and / or fatty acid esters thereof for improving, suppressing or maintaining energy production capacity.
- Energy production refers to the production of energy necessary for humans and non-human animals to maintain their activity. Most of the energy production takes place in mitochondria, one of the organelles. Nutrient sources such as sugars, lipids, and amino acids taken from the diet are metabolized by glycolysis, the pentose phosphate pathway, and the citric acid cycle, and converted to NADH (nicotinamide adenine dinucleotide). The NADH electrons are then transferred to the mitochondrial respiratory chain protein (electron transport chain) to produce energy in the form of ATP (adenosine triphosphate). It is known that when ATP production decreases, for example, in humans, various problems such as obesity due to decreased metabolic capacity, increased risk of developing diabetes, decreased muscle strength, increased fatigue, decreased lethargy / concentration, and depression are caused. There is.
- Maintaining ATP production is important for reducing fatigue, maintaining concentration, exercising with muscles, and maintaining physical and mental vitality.

- the significant difference test was performed by a paired t-test (before and after difference (for fatigue feeling at week 0) #: p ⁇ 0.10). Only in the test food group, the feeling of fatigue at the time of visit tended to improve. From this, it was confirmed that the composition containing sesamin and lutein improves the feeling of fatigue in daily life.
- Table 3 shows the results (change amount of fatigue feeling) analyzed by the formulas (ii) to (iv) using the persons (8 persons per group) who were judged to have appropriately applied the load to the whole body.
- the significant difference test was performed by the paired t-test for comparison before and after the test, and by the unpaired t-test for comparison between groups (before and after difference (for fatigue feeling at week 0) #: p ⁇ 0. 10, ⁇ : p ⁇ 0.05, difference between groups ⁇ : p ⁇ 0.10).
- the improvement in fatigue due to physical load was greater in the test food group. From this, it was found that the composition containing the combination of sesamin and lutein improves the feeling of fatigue when a body fatigue is applied. Ingestion of the test food significantly improved the feeling of fatigue after a break and the next morning. From this, it is considered that the composition containing sesamin and lutein acts on the recovery of fatigue after physical fatigue load and / or mental fatigue load.

Abstract
Description
エネルギー産生の大部分は、細胞内小器官の一つであるミトコンドリア内で行われる。食事から摂取された栄養源である糖、脂質、アミノ酸などが、解糖系、ペントースリン酸経路、クエン酸回路で代謝され、NADH(ニコチンアミドアデニンジヌクレオチド)に変換される。次いで、NADHの電子がミトコンドリア呼吸鎖タンパク質(電子伝達系)に受け渡され、ATP(アデノシン三リン酸)の形でエネルギーが産生される。
ATP産生量が低下すると、例えばヒトでは、代謝能低下による肥満、糖尿病発症リスク増加、筋力の低下、疲労増加、無気力・集中力の低下、うつ病などさまざまな問題が引き起こされることが知られている。
ミトコンドリアの機能低下は、加齢や酸化ストレスにより引き起こされ、ATP産生量が低下することが知られている(非特許文献1及び3)。

ミトコンドリア機能を調べるため、5.5×103cells/wellのTIG-3細胞(胎児肺由来細胞)を専用プレートに播き、37℃、CO2(5%)の条件で24時間培養した。培養24時間後に、セサミン・エピセサミン混合物及びルテインを、それぞれ下記表1に記載の濃度でウェル中の培地に添加し、24時間培養した。培地中のセサミン類に対するルテインのモル比(ルテイン/セサミン類)は、実施例1が0.3、実施例2が3、実施例3が10であった。その後、セサミン・エピセサミン混合物及びルテインを添加した培地を取り除き、ウェル中の細胞を、H2O2(800μM)添加培地で2時間処理した。その後、解析培地に交換し、分析機器(XF analyzer、Agilent株式会社)にて酸素消費速度(pmol/min)を分析した。分析終了後、ヘキストHeで核を染色し、細胞を蛍光顕微鏡BZ-x(株式会社キーエンス)で撮影し、画像解析にて細胞数のカウントを行った。XF analyzerで生細胞の酸素消費の減少量を測定することにより、ミトコンドリア機能を示すATP産生量を評価することができる。具体的には、ウェル中の生細胞の基礎呼吸の酸素消費速度を測定後に、ウェルにATPシンターゼ阻害(オリゴマイシン)を添加し、オリゴマイシン添加による酸素消費速度減少量(pmol/min/103cells)を測定し、ATP産生量とした。基礎呼吸は、ベースライン条件下での細胞エネルギー需要を示し、基礎呼吸の一部がATP生産のために使用される。オリゴマイシンの添加による酸素消費速度減少量はATP産生量を示す。得られた結果を表1に示す。

また、表1に示す実施例1~3及び比較例2~5の「相対値(%)」から100(%)(比較例1)を引いた値を、比較例1に対する「回復率(%)」とした。回復率が高いほど、ATP産生量が多いことを意味する。図1に、実施例及び比較例について求めた回復率(%)(比較例1に対する回復率)を示す。図1中、SEはセサミン・エピセサミン混合物を示す。
図1において、「比較例4+比較例2」は、比較例2の回復率と比較例4の回復率の和であり、「比較例5+比較例2」は、比較例2の回復率と比較例5の回復率の和である。「比較例4+比較例2」及び「比較例5+比較例2」は、セサミン類単独(比較例2)、及び、ルテイン単独(比較例4又は5)の場合の回復率から予測される、セサミン類及びルテインを組み合わせた場合(実施例2及3)の回復率を示す。
比較例2に係るセサミン・エピセサミン混合物(100nM)処理では、比較例1に係るH2O2処理群に対して、2.8%ATP産生量が多かった。以上より、セサミン・エピセサミン混合物処理によるATP産生量の増加、低下抑制又は維持効果を確認した。次に、実施例1~3にかかる、セサミン・エピセサミン混合物(100nM)及び、ルテイン(30nM、300nM又は1000nM)で処理した群、比較例1に係るH2O2処理群に対して、実施例1では17.7%、実施例2では14.3%、実施例3では13.4%ATP産生量が多かった。これは、図1にも示されるように、セサミン・エピセサミン混合物単独で処理した場合のATP産生量の回復率及びルテイン単独で処理した場合のATP産生量の回復率の合算値よりも大きい値であり、単に、ルテイン及びセサミン・エピセサミン混合物処理に対し相加的にATP産生量が増加したのではなく、セサミン・エピセサミン混合物とルテインとの組合せにより、相乗的にATP産生量が増加したことを確認した。すなわち、セサミン・エピセサミン混合物とルテインとを含む組成物は、両者を含むことによるATP産生量の増加、低下抑制又は維持の相乗的な効果を示すため、低用量でも当該効果を発揮することを確認した。
(評価サンプル)
3粒あたりセサミン・エピセサミン混合物10mg、ルテイン10mgを食用植物油脂中にグリセリン脂肪酸エステルで分散させた内容物を、ゼラチンとグリセリンを含む皮膜でカプセル化した食品を製造し、試験食品とした。セサミン・エピセサミン混合物及びルテインを使用しない以外は試験食品と同じ原料を用いて製造した食品を対照食品とした。試験食品及び対照食品は、3粒あたりの熱量、タンパク質量、脂質、炭水化物量は同じであり、また、外観等から両食品は区別ができない状態であった。
加齢に伴い疲れを感じやすくなった40歳以上65歳未満の男女(1群あたり30名)に8週間、対照食品(1日3粒)又は試験食品(1日3粒)を摂取させた。摂取開始前、摂取8週目に検査日を設けた。検査日には、来院後に疲労感(疲労感(1))を測定した。その後、精神的な疲労負荷(精神負荷)としてクレペリン検査(15分間2回、休憩5分)を実施し、終了後に疲労感(疲労感(2))を測定した。その後、身体的な疲労負荷(身体負荷)としてエルゴメーター(エアロバイク(登録商標)EZ101、コナミスポーツ&ライフ)を用いて30分間の運動を実施し、終了後に疲労感(疲労感(3))を測定した。なお、運動強度は日常生活の範囲である3.5~6.8METsに設定した。また、運動強度は個人差がなくなるように調整した。運動後、60分間の休憩をし、疲労感(疲労感(4))を測定した。さらに、翌朝の疲労感(疲労感(5))を測定した。
(8週目の来院時疲労感(1))―(0週目の来院時疲労感(1)) 式(i)
{(8週目の運動負荷直後の疲労感(3))―(8週目のクレペリン検査後疲労感(2))}―{(0週目の運動負荷直後の疲労感(3))―(0週目のクレペリン検査後疲労感(2))} 式(ii)
(8週目の運動負荷60分後の疲労感(4))―(0週目の運動負荷60分後疲労感(4)) 式(iii)
(8週目の翌朝疲労感(5))―(0週目の翌朝疲労感(5)) 式(iv)
除外基準に抵触した被験者(試験食品群6名、対照食品群4名)を除外して解析した来院時の疲労感の変化量の結果を表2に示す。有意差検定は、対応のあるt検定により行った(前後差(0週目の疲労感に対して)♯:p<0.10)。
試験食品群においてのみ、来院時の疲労感が改善する傾向があった。このことから、セサミン類とルテインを含む組成物は日常生活における疲労感を改善することが確認された。
適切に全身への負荷をかけられたと判断した者(1群あたり8名)を用いて、式(ii)~(iv)で解析した結果(疲労感の変化量)を表3に示す。有意差検定は、試験前後の比較は対応のあるt検定により、群間の比較は対応のないt検定により行った(前後差(0週目の疲労感に対して)#:p<0.10,†:p<0.05, 群間差§:p<0.10)。
試験食品の摂取は、休憩後及び翌朝の疲労感を有意に改善した。このことから、セサミン類とルテインを含む組成物は身体的な疲労負荷及び/又は精神的な疲労負荷後の疲労の回復に作用すると考えられる。
