解説トマトに含まれるアルカロイドの一種。トマチンは,花、葉、茎に多く、熟した果実にはほとんど含まれない。多量摂取すると人体に対し毒性がある。化学式C50H83NO21小学館 デジタル大辞泉について 情報 | 凡例
用途トマチンは、溶液からコレステロールを沈殿させるための試薬として用いられている。また、特定のタンパク質抗原の免疫補助剤として知られている。
説明This glycosidic alkaloid has been obtained from the dried leaves of Lycopersicum pimpinelli/olium (Syn. Solanum racemigerum) and also occurs in L. esculentum; L. hirsutum; L. peruvianum; L. peruvianum var. chutatum and L. putatum. The alkaloid forms colourless needles from MeOH and has a somewhat indefinite melting point about 270°C. It is laevorotatory with [α]20D - 30° (pyridine) and on hydrolysis with H2S04 yields tomatidine, I mole of galactose, 2 moles of glucose and 1 mole of xylose. The tetrasaccharide unit is known as lycotetraose. Partial hydrolysis with acid yields a series of products depending upon which, and how many, of the sugar residues are split off from the molecule. Those which have been isolated are: tomatidine lycotriose I (galactose-glucose-glucose); tomatidine lycotriose II (galactose-glucose-xylose); tomatidine lycobiose (galactose-glucose) and tomatidine-galactose.
使用Tomatine is used as an antiproliferatice agent used in the suppression of breast adenocarcinoma cells.
純化方法Tomatine is recrystallised from MeOH, EtOH, aqueous EtOH or dioxane/NH3. It is almost insoluble in pet ether, Et2O or H2O. [Reichstein Angew Chem 74 887 1962, Beilstein 27 III/IV 1954.]

定義ChEBI: A steroid alkaloid that is tomatidine in which the hydroxy group at position 3 is linked to lycotetraose, a tetrasaccharide composed of two units of D-glucose, one unit of D-xylose, and one unit of D-galac ose.
