Antioxidants are very important compounds that are very vital in human health and they have been proven to reduce the risk of diseases such as cancer in human health. Many researchers have used callus to produce antioxidant and most of them used different techniques to get reasonable amounts of antioxidants. The technique used determines the number of antioxidants that will be produced from any explants. Callus Technology involves the techniques of producing callus and metabolites in the presence of explants using different plant hormonal combination in media, different environmental culture condition (light, relative humidity and tempreture), use of elicitors and under a sterile conditions. Callus technology is very promising due to its ability to produce a larger quantity of metabolites (antioxidants) compare to the raw extract of its explants. The use of callus to produce antioxidants is very important and very useful in discovering new plants as a source of antioxidants. The use of callus technology was reviewed for production of antioxidant from the callus of the following plants: Sericostoma pauciflorum, Helicteres angustifolia L, Lepidium sativum L, Randia echinocarpa, Andrographis paniculata Nees, Citrullus colocynthis, Rauwolfia vomitoria Afzel, Decalepis hamiltonii, Bacopa monnieri (Linn.) and Isodon rugosus (Wall. Ex Benth). Callus technology can be utilized to produce antioxidants and other metabolites in industrial quantity. Most of the metabolites from plants have been found to have medicinal values or useful to mankind and antioxidant is one of them.
