Beschreibung
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.
Chemische Eigenschaften
Faintly beige powder
Verwenden
Tomatine is used as an antiproliferatice agent used in the suppression of breast adenocarcinoma cells.
Definition
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.
l?uterung methode
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.]
