saponarin Chem.|sæpəˈnɛərɪn|
Formerly also -ine.
[a. G. saponarin (G. Barger 1902, in Ber. d. Deut. Chem. Ges. XXXV. 1296), f. med.L. sāpōnār-ia (see below and saponary a. and n.) + -in -in1.]
A white or pale yellow crystalline flavonoid diglycoside, 2C27H30O15, first found in soapwort, Saponaria officinalis. Hence saponaˈretin [-etin], a monoglycoside derived from this by hydrolysis.
1902Jrn. Chem. Soc. LXXXII. i. 387 Saponarin dissolves in about 1000 parts of hot water and crystallises on cooling in minute, birefringent needles. 1905G. Barger in Rep. Brit. Assoc. Adv. Sci. 1904 531 Unless the solution be dilute, a second product of hydrolysis separates as a thick yellow oil, which has not yet been obtained crystalline. The name saponaretin is suggested for it. 1923Nature 25 Aug. 304/2 The formation of a glucoside (saponarine) in the mitochondria. 1950Thorpe's Dict. Appl. Chem. (ed. 4) X. 687/1 Saponarin..dried in air is a white powder, but after drying in vacuo becomes pale yellow. 1967Chem. Abstr. LXVI. 10485/2 Saponaretin..was obtained by chromatog[raphy] of flavonoids on a polyamide column. 1969Acta Chemica Scandinavica XXIII. 2910/2 At the time of Molisch's investigation the constitution of saponarin was not known. It is now identified as isovitexin-7-glucoside (apigenin-6-C-7-O-diglucoside). |
