3.1. Phytochemical screening results
The test results indicates that saponins, phenols and tannins were
present in all theleaf extractswhereas phlobatannins and terpenoids
were absent and is shown in Table 1. The mixture of these different
phytochemical compounds has different reducing properties which
mediate the synthesis of nanoparticles by reducing the precursor
(FeSO4). Result confirms the presence of phenolic derivatives and
flavonoids which is essential for free radical scavenging abilities.
Elaborated studies of phytochemical analysis were conducted by
various researchers. Broad screening of phytochemicals for Magnifera
indica reported the presence of polyphenols such as gallic
acid and its derivatives (Pierson et al., 2014). Akhtar et al. (2015)
conducted study on phytochemical classification for 61 medicinal
plants from Pakistan, in which he observed the presence of polyphenols.
Further, he observed total phenol content for Azardirachta
indica as 29.6 ± 4.5 of GAE/g dry weight (expressed as gallic acid
equivalents). Screening results for Murraya koenigii, Azadirachta
indica and Magnolia champaca in the present study is in good
agreement with similar reports found in literature (Haslam and Cai,
1994; Masibo and He, 2008; Kusuma et al., 2011).
