Like other micropropagated medicinal plants, the levels of phytochemicals and the resultant pharmacological potency such as antioxidant activity in the micropropagated D. nobile are important. Although there may not always be a positive correlation between phytochemical content and bioactivity of regenerated plants, it may provide vital information in the critical assessment of the quality of micropropagated plants ( Amoo et al., 2012). In the present study, the antioxidant activity in the different plant parts (both mother and micropropagated) were studied using three antioxidant assays i.e. DPPH, FRAP and metal chelating assays and the data obtained by these antioxidant assays revealed that the methanolic leaf extract of the micropropagated plants showed the highest degree of antioxidant activity ( Fig. 3A, B, C).
