Daucus carota Linn., a herb belonging to the Umbelliferae family, has been reported to possess antifertility activity (Chaudhury, 1966). Garg & Garg (1971a) reported encouraging antifertility activity in the alcoholic and aqueous extracts of the seeds of this herb in female albino rats. No work seems to have been done on the chromatographic fractionation of the different extracts of the seeds of this herb. It was considered worthwhile to undertake this study and the different fractions obtained were tested for antifertility activity in female albino rats.
The air-dried powdered seeds of Daucus carota Linn. were successively extracted with petroleum ether (b.p. 60 to 80° C), 95% alcohol and distilled water in a Soxhlet apparatus. The extracts were evaporated to dryness under reduced pressure. The residues obtained from the petroleum ether
