Contraceptive and biochemical effect of juice extract of Allium cepa, Allium sativum, and their combination in Canton S fruit flies.

This study determines the contraceptive activity of Allium sativa (Garlic) and Allium cepa (Onion) juices on reproductive output and development of Drosophila melanogaster. The fruit flies were divided and grouped into 5, group A serves as the control, group B serves as the onion group, group C serves as the garlic group, group D serves as the onion + garlic group, while group E serves as the standard contraceptive group. Biochemical parameters measured were superoxide dismutase (SOD), Catalase (CAT), Glutathione-S-transferase (GST), malondialdehyde (MDA), nitric oxide (NO), total cholesterol (TC), triglyceride, mating test, and negative geotaxis.
