| Abstract: | Secondary metabolite compounds contained in each plant genus have certain characteristics, which is true also of the flavonoid in the genus "Artocarpus." In the experiment described here, third-year undergraduate students performed the isolation and characterization of cycloartocarpin from the roots of "Artocarpus altilis" (commonly known as breadfruit), giving them experience in skills such as extraction, fractionation, purification, and the structural elucidation of cycloartocarpin. Manipulation of the liquor by thin-layer and gravitation column chromatographic techniques proved to be a simple method to isolate cycloartocarpin. The flavonoid structure, cycloartocarpin, was treated with structure elucidation 1- and 2-dimensional NMR and infrared spectrometry. Students then compared the structure of the cycloartocarpin obtained with that of other flavonoids from the genus "Artocarpus" and other plant genera. From these comparisons, they were able to formulate structural characteristics of the flavonoid compounds of the genus "Artocarpus." The laboratory method, accomplished in four, 3 h laboratory sessions, allowed students to readily understand the process of isolating flavonoids and their peculiarities. |
