“…The 1 H-and 13 C-NMR spectral data of 2 compared to values described by Yun et al (2014) confirmed the presence of trans-cinnamic acid (Figure 1). The analysis of the 1 H-and 13 C NMR spectra of 3 and 4, as well as 5 and 6, revealed the presence of a steroidal skeleton and triterpenic structures, which suggest that the substances in question represent, respectively, a mixture of β-sitosterol and stigmasterol steroids (Alves et al 2010) and 3-β-Ocinnamoyl lupeol and 3-β-O-dihydrocinnamoyl lupeol (Lemos et al 1991), as shown in Table S1 and Figure 1.…”

“…The same trend was followed with the earlier literature reported by earlier (Basuri et al, 2011). Mainly secondary metabolites exert antimicrobial activity through different mechanisms where tannins have been found to form irreversible complexes with prolinerich protein (Shimada, 2006) ) and the major active ingredients like flavonoids, phenolic compounds and some newer isolated compounds are responsible for antimicrobial activity of LC (Yun et al, 2014). Therefore, combination of ethanol and aqueous bark extract of LC showed maximum antibacterial activity by a measured zone of inhibition and revealed more active against Straphyloccus aureus followed by Streptococcus pyogenes followed by ethanolic extract, which showed the same trend but lesser than mixed extract as well as than standard.…”

“…Then, Yun et al [18] also reported that the Lannea coromandelica bark contains a flavonoid compound in quercetin form, which can act as a reducing agent in the synthesis of AgNPs. Jain and Mehata [19] reported that quercetin contained in the Ocimum sanctum is mainly responsible for reducing Ag ions to AgNPs.…”
