In the present investigation twelve indigenous medicinal plants have been screened for their antiimplantation activity in albino rats. The plant material was subjected for soxhlation successively and separately from non-polar solvents to polar solvents i.e., petroleum ether benzene and ethanol. Out of these three extracts the petroleum ether extract of seeds of Citrus medica, aerial part of Oxalis corniculata and Tinospora cardifolia have showed maximum antiimplantation activity. Ethanol extract of leaves of Cardiospermum helicacabum, roots of Echinops echinatus, leaves of Melia azedarach, seeds of Momordica charantia and bark of Terminalia bellirica have shown maximum antiimplantation activity amongst the three extracts of each plant material screened. Though all the three extracts of seeds of Annona squamosa and leaves of Zizyphus jujube screened for antiimplantation activity, no extract has showed any loss in implantation. The details of the results obtained are discussed.

Petroleum ether, benzene and alcohol extracts of the seeds of C. juncea were tested for antiimplantation and pregnancy interruption activities in female albino rats. Of these three extracts, the alcohol extract was found to be the most effective in causing antiimplantation and pregnancy interruption activities. These adverse effects on fertility are reversible upon withdrawal of the extract treatments. The alcohol extract was found to possess estrogenic activity. After subjecting to preliminary phytochemical screening, the alcohol extract showed positive tests for alkaloids, steroids, glycosides, saponins, flavonoides, fixed oils, phenols and tannins.

In the present study, the hydro alcoholic extract of Moringa concanensis and their different fractions were evaluated for it's anti implantation, abortifacient, estrogenic and antiestrogenic activity. Hydro alcoholic extract of Moringa concanensis has showed potent antiimplantation and abortifacient activity at 200 mg/kg and 400 mg/kg respectively and marked estrogenic activity when administered individually and anti estrogenic activity was observed when administered along with ethinyl estradiol (1 ${\mu}g/rat/day$) as well as their different fractions of Moringa concanensis showed significant antiimplantation and abortifacient activity at 100 mg/kg. Moreover, all tested fractions showed significant anti estrogenic activity when administered simultaneously with ethinyl estradiol.

The preliminary antifertility test of Dictamnus albus(Rutaceae) showed that a methanol extract of root bark decreased fertility in rats when administered orally on days $1{\sim}10$ postcoitum. Hexane, chloroform, butanol and aqueous fractions from the methanol extract, were tested to produce the result that only the hexane fraction exhibited positive activity. The hexane fraction was subfractionated into acidic, alkaloidal and neutral subtractions and tested. Neutral subtraction showed positive activity. From the neutral subtraction, fraxinellone was isolated as an active principle. The timed-dosing experiments revealed that antifertility activity of fraxinellone appeared to be exerted after tubal exit of the ova to prevent implantations.
