Echinocystis lobata, leaves, flowers, fruits, seed, biological activity


Echinocystis lobata (Mich.) Torr. et Gray extracts were investigated for their bioactive compounds and their potential for natural antioxidant properties. In vitro antioxidant activity of methanol, ethanol, and water extracts were evaluated by
1,1-diphenyl-picrylhydrazyl (DPPH) radical scavenging activity. Total phenolic content (TPC) and total flavonoid content (TFC) of fruits and seeds were determined. TPC is a fairly constant value and varies weakly both among the different organs of Echinocystis lobata and among the geographical locations of the populations studied. Like other invasive species, Echinocystis lobata is superior to many other plants in terms of the total amount of flavonoids contained in its fruits and seeds. The dried fruits contain more flavonoids than the seeds. Seeds from Slovak populations have higher flavonoid content than those from Russian populations. The results demonstrated that Echinocystis lobata can be a good source of natural antioxidants and have a great potential for commercialization, especially in the pharmaceutical industry.
