- Carob is distributed in various places such as the Mediterranean coast, California in the United States and Australia, and is mainly planted in various places in China such as Guangxi, Sichuan, Yunnan and Guangdong. Carob is low in calories and fat, and is rich in natural polysaccharides, multiple vitamins, proteins and trace elements. At present, carob extract is mainly used in the fields of food flavoring, natural food thickeners and stabilizers. Carob is not only very nutritious, but also has extremely high medicinal properties. Syrup made from carob pods can play a good relieving effect on colds, coughs and sore throats. The main component of carob pods is sugar.

(1)イナゴマメ多糖類Hocacyの分子量測定
イナゴマメ多糖類Hocacy 10.0mgを精確に計量し、濃度2mg/mLの溶液を調製した。ゲル浸透クロマトグラフィー(GPC)、示差屈折率検出器および光散乱検出器で検出を行い、移動相を0.1mol/LのNaNO3溶液とし、流速を0.7mL/minとした。
イナゴマメ多糖類Hocacyサンプル5mgを計量し、乾燥KBrを適量加えて研磨し、均一かつ透明な錠剤を作製して、4000cm-1~400cm-1の範囲において、フーリエ変換赤外分光光度計を用いて分析を行った。
イナゴマメ多糖類Hocacyサンプル5.5mgを計量し、2mol/Lのトリフルオロ酢酸(TFA)を1mL加え、窒素ガスを充填して密閉し、110℃で120分間加熱して、加水分解させた。分解されたサンプルを溶解した後、NaBH490mgを加えて、還元反応を4時間行った。還元されたサンプルをオーブンに入れて乾燥させ、無水酢酸5mLを加え、110℃でアセチル化を行った。最終のアセチル化単糖類を酢酸エチルで溶解し、メンブレンを通過させ、GC-MSによって構造を同定した。
イナゴマメ多糖類Hocacyサンプル20mgを計量し、ジメチルスルホキシド(DMSO)6mLに溶解して、多糖類サンプルが完全に溶解するまで、40℃で15時間磁気攪拌した。イナゴマメ多糖類Hocacyに対してメチル化、加水分解およびアセチル化処理を行った後、GC-MSによりトータルイオンクロマトグラムを得、それは図3が示すとおりである。図3において、横軸のTimeはピーク検出時間、縦軸のRelat ive abundanceは相対強度を示す。イナゴマメ多糖類Hocacyのメチル化後の赤外吸収スペクトルは図12が示すとおりである。
イナゴマメ多糖類Hocacy(実施例1で調製したもの)の、アンモニア水によって咳をするように誘発・刺激されたマウスの気道機能に対する影響に関する実験
マウスを濃アンモニア水が入った大型ビーカーに入れ、マウスの咳を誘発した。
実験を5群に分け、各群を以下のとおりにした。即ち、第1群を生理食塩水を投与する空白群とし;第2群をベンプロペリンリン酸塩(Tonghua Changcheng Pharmaceutical Co.,Ltd.、承認番号:H22020149)を投与する陽性群(60mg/kg)とし;第3~5群を、イナゴマメ多糖類Hocacyを低用量(100mg/kg)、中用量(200mg/kg)および高用量(400mg/kg)で投与する投与群とし;14日間強制経口投与した。最後の強制経口投与が完了した1時間後に、1000mLの大型ビーカーを逆さに実験台に置き、噴霧器で25%の濃アンモニア水を10秒間噴霧し続けた後、マウスを大型ビーカーに入れ、時間の計測を始め、腹筋の収縮、口を大きくした呼吸、および咳の音を指標とし、マウスがビーカーにおいて初めて咳をした時までの時間(潜伏期)および2分以内の咳の回数を記録し、その結果は表2が示すとおりである。結果によって、アンモニア水で刺激し、咳を誘発した後、各群のマウスの咳の度合いが異なり、高・中・低用量のイナゴマメ多糖類Hocacyがいずれもアンモニア水によるマウスの咳の回数を顕著に低減し、潜伏期を延長でき、空白群に比べて、顕著もしくは非常に顕著な効果を示すこと(****p<0.0001、***p<0.001、**p<0.05)が示され、イナゴマメ多糖類Hocacyが、アンモニア水によるマウスの咳に対して、ある程度の咳止めの作用を有し、用量依存性を呈することが示されている。高用量群(400mg/kg)の咳止め効果は最も顕著であり、高・中用量群の初回の咳までの時間はいずれも陽性群より顕著に延長されている(p<0.01、p<0.05)。
各群のマウスに引き続き2日間投与を行い、16日目に、最後の投与の30分後に、0.5mL/匹で5%のフェノールレッド生理食塩水を腹腔内注射し、注射の30分後に頸椎脱臼法により安楽死させた。甲状軟骨から気管支にかけての気管を切り取り、マウス気管内のフェノールレッドが完全に放出されるように、生理食塩水3mLと1moL/Lの水酸化ナトリウム溶液0.1mLで10分間超音波洗浄した。溶液の吸光度を546nmで測定し、標準曲線の回帰式に従ってフェノールレッドの含有量を計算し、結果は表3が示すとおりである。結果は、イナゴマメ多糖類Hocacyがいずれもマウスの気管のフェノールレッド分泌量を顕著に向上させることができ、生理食塩水に比べていずれも有意差があること(***p<0.001)を示し、イナゴマメ多糖類Hocacyがある程度の痰を減らす作用を有することを示している。高用量の場合、陽性群に比べて有意差があり(p<0.005)、用量依存性を呈する。イナゴマメ多糖類Hocacyのマウスのフェノールレッド分泌量に対する影響を示す模式図は図15が示すとおりである。
イナゴマメ多糖類Hocacy(実施例1で調製したもの)のゼブラフィッシュのT細胞の減少に対する改善効果
T細胞が赤色蛍光を発するように遺伝子組み換えを行ったゼブラフィッシュは、自然交配により繁殖したものである。受精後3日齢(3dpf)のゼブラフィッシュをすべて、28℃の魚養殖水(水質:1L当たりの逆浸透水に、200mgの速溶性海塩を加えたものであり、伝導率が450~550μS/cmであり、pHが6.5~8.5であり、硬度が50~100mg/L CaCO3である)で飼育し、ゼブラフィッシュは北京環特智魚優検生物科技有限公司の養魚センターが繁殖し、提供したものである。
