  1. NI means not identified, standard (std) means that the identity of the compounds were confirmed by comparing with the retention time and ultraviolet–visible (UV–Vis) spectra of standard compounds, and nuclear magnetic resonance (NMR) means that the compounds were confirmed by proton (1H) and carbon-13 (13C) NMR analysis, followed by heteronuclear multiple bond correlation (HMBC) and heteronuclear single quantum correlation (HSQC) experiments
