The parts of eggplant Solanum melongena L. (Solanaceae) (leaf, stem, root, flower, and fruit) were taking in two stages, vegetative and flowering stage (Iraq), to determine the influence of total content of plenolic compounds, (as phenol, flavonoid, tannin, and anthocyanin), alkaloids compound and antioxidant capacity of crude extract of these parts. Ultrasonic extracted by ethyl-acetate solvent, qualitative assay by deferent reagent. The flowers showed high content of phenolic compound as phenol, tannin, anthocyanin, and flavonoids, and antioxidant capacity, while seeds showed high content of alkaloids with significant value, p<0.05. Stage of growth of roots, stems, and leave showed no significant differences effect in phenol content, otherwise, the flowering stage of roots, stems, and leave showed high content of flavonoids with significant value compared with vegetative stage Flowering stage of roots and stems showed high content of tannin with significant value compared with vegetative and flowering stage otherwise in leave. Vegetative stage of roots showed high value of anthocyanin content with significant value, compared with flowering stage. Otherwise, the vegetative stage of roots, stems, and leave showed high content of alkaloids with significant value high value of flowering stage. Antioxidant capacity were the best in vegetative stage of roots, stems, and leave compared with the flowering stage in conjunction with alkaloids.
