Preliminary separation of the components in the crude petroleum ether extract of Caesalpinia Pulcherrima flowers
The crude petroleum ether extract of the orange-flowered variety of Caesalpinia pulcherrima was subjected to column chromatographic separation. Three fractions were obtained and were labeled as Cpx1, Cpx2, and Cpx3. Toxicity test of those fractions on cockroaches showed Cpx3 to have the highest perc...
