Introduction to the antioxidant properties of guava acid from cactus extract

Cactus, Latin name: Opuntiaficus-indica (L.) Mill, commonly known as Cactus, is a perennial fleshy shrub or small tree of the genus Cactus in the family Cactaceae. The original Ministry of Health Notice No. 19 of 2012 has identified the pear-fruit cactus as a common foodstuff.

Cactus extract, a natural product derived from cactus, is a useful "recovery agent" for exercise, as a post-exercise intervention to increase plasma insulin can promote the recovery of muscle glycogen reserves. In addition, the polysaccharides, flavonoids and guava acids contained in cactus are effective in scavenging excess free radicals from the body, thus acting as an antioxidant.

Introduction to the antioxidant properties of guava acid from cactus extract

Guava acid has a weak scavenging capacity for DPPH but a strong scavenging capacity for -OH, an important reactive oxygen species that kills red blood cells and degrades DNA, cell membranes and polysaccharide compounds, while guava acid has a significant scavenging effect on -OH, indicating that it may have strong antioxidant activity and anti-ageing activity.
