Chrysoeriol-7-rutinoslde has been isolated from the seeds of Crotalariu saltiuna. Plant. Crotalaria saltiana Andr. (Leguminosae-subfamlly-Lotoideae).Source. Calcutta (West Bengal).Previous work. On sister species.'Present work. Dry powdered seeds of C. saltiana extracted with hot 80 % alcohol and the alcoholic extract fractionated with n-hexane, ether, EtOAc and MeCOEt. Ether fraction contained no free flavone.Chrysoeriol-7-rutinoside (from EtOAc and MeCOEt fractions), O-1 "/;: yield, m.p. 260- 265", not soluble in usual organic solvents, soluble in pyridine, not hydrolysable by 7% H,S04 but on boiling with 10% H,SO, in glacial HOAc medium for 5 hr hydrolysed to chrysoeriol (R,, co-chromatography with authentic sample from Rungia repens, h,,, (EtOH) 270, 345 nm, acetate, m.p. 218-220") and glucose and rhamnose (R, and co-chromatography) in equal proportion.Aq. portion, after MeCOEt extn., contained a glycoside with R,: 0.69 (15 % HOAc), 0.83 (60 % HOAc), O-50 (BAW 4: I .5), 0.64 (water sat. phenol), 0.58 (t-BuOH-HOAc-H20, 3: 1: 1) (Whatman No. 1, temp. 30") which when hydrolysed with 7% H,S04 gave luteolin (R, and co-chromatography) and glucose. It appears to be a luteolin-tnglucoside.This is the first record of the occurrence of a chrysoeriol glycoslde in the genus Crotalaria.
