A total of ten plants were tested for their antioxidant potential. Leaves were studied for flavonoids and phenolic
content. The total antioxidant activity was also calculated in all of them. The results are represented in Table 1. Total
phenolics were estimated spectrophotometrically using Folin-Ciocalteu method. It was observed that Mangifera
indica exhibited highest total phenolics content; while minimum was observed in Combretum indicum. Significant
variability was observed when one way ANOVA was applied with (P< 0.05). A previous comparative study of total
phenolic content in some fruits also revealed that Mangifera indica has highest phenolic contents; while significant
variation amongst different fruits in polyphenolic contents was established [11]. Further it was reported by Naseer et
al., (2014) that Azadirachta indica possesses more phenolic content than those reported in Mangifera indica, and
therefore Azadirachta indica is a better source for polyphenolics [12]. Comparative study by Srivastava et al., (2013)
for total phenolic content in fruits also revealed that Mangifera indica is having good phenolic activity and the
maximum flavonoid/phenolic ratio (F/P ratio) was found in Lactuca sativa which is a leaf vegetable [13]. In our
study when total flavonoids were estimated spectrophotometrically using Quercetin (QE) as standard, Morus nigra
exhibited highest total flavonoid content; whereas Combretum indicum had the lowest levels. The study by Iqbal et
al., (2012) also supports that the flavonoid content is higher in Morus nigra as compared to other species [14].
Additionally, for flavonoids significant variability was observed when one way ANOVA was applied with (p <
.005). In the present study, F/P ratio was found to be highest in Morus alba, whereas Sulaiman et al., (2012), having
studied twenty medicinal plants, recorded the highest F/P ratio in Cassia fistula
