Antioxidant Potential of Canna: an overview

Abstract

Canna, the solitary genus of the family Cannaceae and order Zingiberales, comprises of about 51 species of flowering plants. Canna species are native of South America but with the course of time they have been distributed throughout the world. It is an important plant not only from the ornamental point of view but also it is an important plant for starch production as well as its medicinal values. From the primitive time, village people commonly use Canna as herbal medicines in their daily dealings. Different plant parts like rhizome and leaves of Canna have been used for the treatment of inflammatory diseases, fever, hypertension, diabetes, menstrual disorders, malaria etc. Phytochemicals with high antioxidant activities reported from the members of genus Canna. Moreover, isolation and identification of chemical compounds shows the presence of derivatives of polysaccharide, anthocyanin and phenylpropanoid compounds. The present study reflects a comprehensive review on biological activities of Canna species with special reference to some other members of Zingiberales.

In vitro Antioxidant and free radical scavenging activity of Macrotyloma uniflorum dal from Kumauni region

“…Correlation between the total flavonoids and the DPPH was also established for DME (R 2 = 0.502) as well as between flavonoids and reducing power and was found to be DME (R 2 = 0.841). The positive linear correlation between total contents of phenolics and DPPH free radical scavenging activities were in accordance of previous studies 13 .…”

“…The total flavonoid content was found to be maximum in case of DME of Macrotyloma with 139.5 ± 55.09 mg/ml QE equivalent per 100 mg plant extract. Higher level of flavonoids in DME can be attributed to the fact that methanol is less polar than water and thus has the potential to release the bound flavonoids and polyphenols from the cell wall of the plant 13,14 .…”
