Abstract
Description
(1)コラーゲン遺伝子の発現量を増加させ、コラーゲンの産生を促進することができる。
(2)古来から食用とされているイナゴマメの莢果由来の化合物を有効成分とするものであるため、人体に対する安全性が高い。
1.イナゴマメ莢果の含水アルコール抽出物の調製
採取後、乾燥処理されたイナゴマメ(Ceratonia siliqua)の莢付果実から種を取り除いた。このイナゴマメの莢果を粉砕機で粉砕して粒径2mm以下の粉砕物を得た。20kgの粉砕物に対し、140kg(7倍量)の含水95%エタノールを加え、1.5時間還流抽出する操作を2回行った後、残渣をさらに140kg(7倍量)の含水70%エタノールで1.5時間還流抽出した。得られた還流抽出液を合わせた後、溶媒を減圧留去してイナゴマメ莢果の含水エタノール抽出物12.4kgを得た。
2.イナゴマメ莢果の含水アルコール抽出物の分離及び精製
実施例1で得られたイナゴマメ莢果の含水エタノール抽出物を1~10倍量の水に分散させ、イオン交換樹脂(マクロポーラス吸着樹脂D101、Cangzhou Bon Adsorber Technology Co., Ltd.)に吸着させた。カラム容量の3倍量の蒸留水で溶出して糖類等の不純物を除去した後、カラム容量の3倍量の含水95%エタノールで溶出させ、溶媒を減圧留去し、462.7gのエタノール溶出画分(非炭水化物系低分子化合物画分)を得た。次に、得られたエタノール溶出画分を1.0Lの含水50%メタノールに分散させ、石油エーテル、酢酸エチルの順に、それぞれ5回ずつ液液抽出を行った。各溶媒を減圧留去して、石油エーテル画分28.4g、酢酸エチル画分139.4g及び水系画分290.2gをそれぞれ得た。
3.化合物(Ceratonia siliqua A)の構造解析
実施例2で得られた化合物、「Ceratonia siliqua A」の構造解析を行った。構造解析にあたり、高分解能質量分析(HR-ESI-MS;負イオンモード)、紫外吸収スペクトル分析、赤外吸収スペクトル分析、1H-NMR、13C-NMR、HMBC、HSQC及びNOESY分析を行った。これらの分析に用いた装置は次のとおりである。
・高分解能質量分析:エレクトロスプレーイオン化四重極飛行時間型質量分析装置(Bruker Daltonics社製品)
・紫外吸収スペクトル分析:紫外可視分光光度計(UV-2401PC、株式会社島津製作所製品)
・赤外吸収スペクトル分析:FT-IR(NEXUS470、Thermo nicolet社製品)
・NMR分析:600MHz核磁気共鳴装置(AVANCE III 600、Bruker社製品)
・性状:黄色粉末
・HR-ESI-MS(negative) m/z:507.1180[M-H]-
・紫外吸収スペクトル:λmax(MeOH)nm (logε):192.2(3.82),218.0(4.26),291.0(4.02),322.4(3.95)
・赤外吸収スペクトル(KBr、cm-1):νmax:3378.33,1699.52,1630.21,1603.89,1515.90,1451.32,1351.12,1326.00,1270.16,1214.57,1186.83,1126.01,1070.65,1031.88,816.60,765.83,624.09,580.17,537.28,522.40
4.Ceratonia siliqua Aのコラーゲン遺伝子の発現促進作用の検討
実施例2で得たCeratonia siliqua Aを用いて、ヒト表皮由来角化細胞株であるHaCaT細胞におけるコラーゲン遺伝子(COL1A1遺伝子)の発現促進効果を調べた。
