Furthermore, the novel Megastigman compound and flavonoid compound of the fifth aspect of the present invention have the fat metabolism improving action as described above, and can be used as a fat metabolism improving agent.

次に、本発明を実施するための最良の形態につき説明するが、本発明の範囲はこの実施の形態のみに限定されるものではない。   Next, although the best mode for carrying out the present invention will be described, the scope of the present invention is not limited only to this embodiment.

本発明の第1の態様の脂肪代謝改善剤としては、垂盆草の全草を用いたものを例示することができる。垂盆草の全草を用いる場合は、垂盆草の全草をそのまま用いることができるし、又は、粉砕、破砕、切断、すりつぶしなどによる形状変化を行ったもの、もしくは、乾燥などの調製を実施したものを用いることもできる。   Examples of the fat metabolism improving agent according to the first aspect of the present invention include those using whole botanical plants. When using the whole bonsai grass, the whole bonsai grass can be used as it is, or the shape of the bonsai grass has been changed by crushing, crushing, cutting, grinding, etc. What was implemented can also be used.

本発明の第1の態様の脂肪代謝改善剤としては、又、垂盆草を、水、低級脂肪族アルコールもしくは低級脂肪族アルコールの含水物により抽出して得られる抽出液、又はその抽出エキスを用いたものも例示することができる。   As the fat metabolism improving agent of the first aspect of the present invention, an extract obtained by extracting bonbon grass with water, a lower aliphatic alcohol or a hydrated product of a lower aliphatic alcohol, or an extract thereof, What was used can also be illustrated.

この抽出液は、垂盆草の全草をそのまま、水、低級脂肪族アルコール及び低級脂肪族アルコールの含水物より選ばれる抽出溶媒により、抽出して得ることもできるが、垂盆草の全草を、粉砕、破砕、切断、すりつぶしなどによる形状変化を行ったものを用いて抽出する方法が、抽出効率の面で好ましい。   This extract can also be obtained by extracting the whole bonsai grass with an extraction solvent selected from water, a lower aliphatic alcohol and a lower aliphatic alcohol hydrate, A method of extracting the material using a material whose shape has been changed by crushing, crushing, cutting, grinding or the like is preferable in terms of extraction efficiency.

抽出溶媒として用いられるアルコールとしては、炭素数1〜4の低級アルコール類が挙げられ、具体的には、メタノール、エタノール、プロパノール、イソプロパノール、nブタノール、イソブタノール、t−ブタノール又はこれらの混液が挙げられる。抽出溶媒としては、好ましくはこれらのアルコール、又はこれらのアルコールに30容量%までの水を含有する含水アルコールが用いられる。前記のアルコールの中でもメタノール又はエタノールが好ましい。これらの抽出溶媒は、抽出材料に対して、1〜50倍(重量)程度、好ましくは10〜30倍程度用いられる。   Examples of the alcohol used as the extraction solvent include lower alcohols having 1 to 4 carbon atoms, specifically, methanol, ethanol, propanol, isopropanol, n-butanol, isobutanol, t-butanol, or a mixed solution thereof. It is done. As the extraction solvent, these alcohols or hydrous alcohols containing up to 30% by volume of water in these alcohols are preferably used. Of the above alcohols, methanol or ethanol is preferred. These extraction solvents are used in an amount of about 1 to 50 times (weight), preferably about 10 to 30 times the extraction material.

抽出温度は、室温〜溶媒の沸点の間で任意に設定できるが、例えば50℃〜抽出溶媒の沸点の温度で、振盪下もしくは非振盪下または還流下に、前記の抽出材料、即ち、垂盆草の全草、又は、それを粉砕、破砕、切断、すりつぶしなどによる形状変化を行ったもの等を、前記の抽出溶媒に浸漬することによって行うのが適当である。   The extraction temperature can be arbitrarily set between room temperature and the boiling point of the solvent. For example, at the temperature of 50 ° C. to the boiling point of the extraction solvent, the above-described extraction material, that is, the hanging basin, can be shaken or non-shaken or refluxed. It is appropriate to immerse the whole grass of the grass or the one whose shape has been changed by crushing, crushing, cutting, mashing, etc. in the extraction solvent.

好ましい抽出時間は、抽出温度や抽出の際の振盪の有無等により変動し、特に限定されない。例えば、抽出材料を振盪下に浸漬する場合には、30分間〜10時間程度行うのが適当であり、非振盪下に浸漬する場合には、1時間〜20日間程度行うのが適当である。又、抽出溶媒の還流下に抽出するときは、30分間〜数時間加熱還流するのが好ましい。なお、50℃より低い温度で浸漬して抽出することも可能であるが、その場合には、前記の時間よりも長時間浸漬するのが好ましい。抽出操作は、同一材料について1回だけ行ってもよいが、複数回、例えば2〜5回程度繰り返すのが好ましい。   The preferred extraction time varies depending on the extraction temperature and the presence or absence of shaking during extraction, and is not particularly limited. For example, when the extraction material is immersed under shaking, it is appropriate to carry out for about 30 minutes to 10 hours, and when it is immersed under non-shaking, it is appropriate to carry out for about 1 hour to 20 days. Moreover, when extracting under reflux of an extraction solvent, it is preferable to heat to reflux for 30 minutes to several hours. In addition, although it is possible to extract by immersing at a temperature lower than 50 ° C., it is preferable to immerse for a longer time than the above time. The extraction operation may be performed only once for the same material, but is preferably repeated a plurality of times, for example, about 2 to 5 times.

前記の抽出工程により得られた抽出液には垂盆草の含有成分が溶出されている。本発明の脂肪代謝改善剤には、このようにして得られた抽出液をそのまま加えてもよいが、前記抽出液を濃縮して抽出エキスにして脂肪代謝改善剤としてもよい。濃縮は、低温で減圧下に行うのが好ましい。なお、濃縮する前に濾過して濾液を濃縮してもよい。抽出エキスは、濃縮したままの状態で脂肪代謝改善剤として用いることができるが、また、濃縮は乾固するまで行ってもよく、粉末状又は凍結乾燥品等として用いてもよい。濃縮する方法、粉末状及び凍結乾燥品とする方法は、当該分野での公知の方法を用いることができる。   In the extract obtained by the extraction process, the components contained in the bonsai are eluted. The extract obtained in this manner may be added as it is to the fat metabolism improving agent of the present invention, but the extract may be concentrated to obtain an extract extract as a fat metabolism improving agent. Concentration is preferably carried out at a low temperature and under reduced pressure. The filtrate may be concentrated by filtration before concentration. The extract can be used as a fat metabolism-improving agent in a concentrated state, but the concentration may be performed until dryness, or may be used as a powder or lyophilized product. As a method of concentrating, a method of forming a powder and a lyophilized product, a method known in the art can be used.

このようにして得られる抽出液又は抽出エキスを、精製処理に付し、含有される各成分に分離することができる。そして、分離された成分中には、脂肪代謝改善作用を有する化合物が含まれており、これらも脂肪代謝改善剤として用いることができる(本発明の第2の態様)。   The extract or extract thus obtained can be subjected to a purification treatment and separated into each component contained. The separated component contains a compound having an action of improving fat metabolism, and these can also be used as an agent for improving fat metabolism (second aspect of the present invention).

精製処理は、例えば、クロマトグラフ法、イオン交換樹脂を使用する溶離法、溶媒による分配抽出等を単独、又は組み合わせて採用することができる。クロマトグラフ法としては、順相クロマトグラフィー、逆相クロマトグラフィー、薄層クロマトグラフィー、遠心液体クロマトグラフィー、高速液体クロマトグラフィー等を挙げることができ、これらのいずれか、又はそれらを組み合わせで行う方法が挙げられる。この際の担体、溶出溶媒等の精製条件は、各種クロマトグラフィーに対応して適宣選択することができる。   As the purification treatment, for example, a chromatographic method, an elution method using an ion exchange resin, partition extraction with a solvent, or the like can be employed alone or in combination. Examples of chromatographic methods include normal phase chromatography, reverse phase chromatography, thin layer chromatography, centrifugal liquid chromatography, high performance liquid chromatography, and the like, and any one of these or a combination thereof may be used. Can be mentioned. In this case, purification conditions such as a carrier and an elution solvent can be appropriately selected according to various chromatographies.

抽出液又は抽出エキスを、精製処理に付し、各成分に分離することにより、前記の構造式(1)〜(9)のいずれかで表される新規化合物を得ることができ、それぞれ以下に示すように命名した。   A novel compound represented by any one of the structural formulas (1) to (9) can be obtained by subjecting the extract or extract to a purification treatment and separating it into each component.

The test method is shown below.

大日本住友製薬社より購入したヒト肝がん由来HepG2細胞を用いた。培地はminimum essential medium Eagle(MEM,シグマ−アルドリッチ社)に10%(v/v)fatal calf serum(FCS)及び100units/mLペニシリンG、100μg/mLストレプトマイシン及び0.1mM非必須アミノ酸(インビトロジェン社)を添加して使用した。細胞の培養は、75cm培養フラスコ(ファルコン社)中で行い、5%CO雰囲気下37℃にて行った。継代操作は,培養した細胞をダルベッコPBS(−)(日水製薬社)で洗浄した後、0.02%(w/v)トリプシン(ディフコ社)及び0.05%(w/v)EDTA・2Na(同人化学社)を含むPBS(−)により剥離して、定法に従い行った。 Human liver cancer-derived HepG2 cells purchased from Dainippon Sumitomo Pharma Co., Ltd. were used. Medium is medium essential medium Eagle (MEM, Sigma-Aldrich) 10% (v / v) fatal calf serum (FCS) and 100 units / mL penicillin G, 100 μg / mL streptomycin and 0.1 mM non-essential amino acids (Invitrogen) Was used. The cells were cultured in a 75 cm 2 culture flask (Falcon) at 37 ° C. in a 5% CO 2 atmosphere. In subculture, the cultured cells were washed with Dulbecco's PBS (-) (Nissui Pharmaceutical), then 0.02% (w / v) trypsin (Difco) and 0.05% (w / v) EDTA. -It peeled by PBS (-) containing 2Na (Doujin Chemical Co., Ltd.), and performed according to a conventional method.

HepG2細胞を10cells/well(200μL/well)の細胞密度で48穴培養プレート(住友ベークライト社)に播種して実験を行った。培養1日後、被験サンプルを含む高濃度グルコース(4500mg/L)含有DMEM(200μL/well)に培地交換して計6日間(2日に1回培地を交換)培養した。高濃度グルコース含有DMEMによる培養終了後、被験サンプルを添加した低濃度グルコース(1000mg/L)含有DMEM(200μL/well)に培地交換して、さらに20時間培養した。 HepG2 cells were seeded in a 48-well culture plate (Sumitomo Bakelite) at a cell density of 10 5 cells / well (200 μL / well). After 1 day of culture, the medium was replaced with high-concentration glucose (4500 mg / L) -containing DMEM (200 μL / well) containing the test sample, and cultured for a total of 6 days (medium was changed once every 2 days). After completion of the culture with high-concentration glucose-containing DMEM, the medium was changed to low-concentration glucose (1000 mg / L) -containing DMEM (200 μL / well) to which the test sample was added, and the culture was further continued for 20 hours.

培養期間終了後、培養上清を除去、次いで蒸留水(100μL/well)を加え、超音波破砕機にて細胞を破砕した後、培養プレートを遠心分離(3000rpm,10min,r.t.)に付し細胞破砕液を得た。得られた細胞破砕液の中性脂肪濃度及びタンパク質濃度は、それぞれ市販キットであるトリグリセリドEテストワコー(和光純薬工業社)及びBCAprotein assay kit(Pierce社)を使用して定量した。尚、定量結果については、タンパク質あたりの中性脂肪量(下表のTG/Protein)で算出し、対照群に対する相対値(% of control)として表した。   After completion of the culture period, the culture supernatant was removed, distilled water (100 μL / well) was added, the cells were disrupted with an ultrasonic disrupter, and the culture plate was centrifuged (3000 rpm, 10 min, rt). A cell disruption solution was obtained. The triglyceride E test Wako (Wako Pure Chemical Industries) and BCAprotein assay kit (Pierce), which are commercially available kits, were used to quantify the neutral fat concentration and protein concentration of the obtained cell lysate, respectively. In addition, about the quantitative result, it calculated by the amount of triglycerides per protein (TG / Protein of the following table), and expressed as a relative value (% of control) with respect to a control group.
