“…However, the excess distortion caused by the addition of Bi 3+ in the case of x ! 0.18 may be another reason for decreasing the emission intensity, as reported in the reference [16]. The excitation spectra of the Y 0.5Àx Gd 0.35 Eu 0.15 Bi x NbO 4 phosphor, which was taken at the emission wavelength of 614 nm, are shown in Fig.…”

“…Furthermore, the bioactive compounds suspected of being natural antioxidants in S. alba leaves beside the 6-Methoxy-7-hydroxycoumarin, are: Isoliquiritigenin is a flavonoid (isoflavan) which has bioactive potential as an anti-inflammatory, anti-bacterial and antioxidant (Trinh et al, 2015;Xiao et al, 2017). This compound is also widely found in plants such as Glycyrrhiza uralensis as reported by Watanabe (Watanabe et al, 2016).…”

The purpose of this study was the bioactive identification of ethanol extracts (EtOH) from the bark and leaves of Sonneratia alba that have antioxidant activity. Mangrove bark and leaf powder each added with ethanol (1: 3, w/v) sonicated for 10 minutes. The obtained extract was tested for phytochemicals, antioxidant activity using DPPH and identification of the compounds using UPLC-ESI-MS. The ethanol extract from the bark and leaves of S. alba contains bioactive compounds that have antioxidant activity from the group of phenol compounds and the both extracts contain 7-hydroxycoumarin or scopoletin. The antioxidant activity (IC 50 value) of each extract was 67,211±2,482 g/ml and 88,706±4,782 g/ml, respectively. Ethanol extract from bark and leaves of S. alba has the potential to be an antioxidant agent.

“…And there are also other researchers who state that Saga leaf ethanol extract (Abrus precatorius) can inhibit S. mutans with the smallest inhibitory zone at a concentration of 1%, which is 6.06 mm, while the largest at a concentration of 10% is 18.02 mm (Nisak et al, 2021). Several structures of compounds that were successfully isolated from A. precatorius (Xiao et al, 2017;Okoro et al, 2021) can be seen in Figure 1. With the potential of Saga herbaceous plants against antibacterials, it is necessary to research more specific Saga herbaceous plants against the antibacterial S. mutans.…”

Antibacterial is a substance that can inhibit growth or can even kill bacteria that cause infection. One of them is infection with Streptococcus mutans bacteria that cause damage to teeth, such as dental caries. Dental caries is a disease that affects many adults and children, permanently damaging the tooth layer and forming small holes in the teeth. The purpose of this study was to find active compounds from the herb Saga plant (Abrus precatorius), which has the potential to be antibacterial of S. mutans in silico. The methods used are pharmacokinetics and toxicity screening, Lipinski's Rule of Five, as well as simulations of molecular docking and molecular dynamics. The Abruquinone D (-6.43) and Abruquinone F (-7.08) were predicted to have stable interactions and be similar to amoxicillin (-7.69) and native ligand (-8.56 kcal/mol) based on the results of screening and molecular docking simulations of active compounds from Saga herbaceous (Abrus precatorius) against deoxycytidylate deaminase receptors. Molecular dynamics findings confirmed by MMGBSA methods that Abruquinone D (-41.3876 kcal/mol) had a lower energy value than Abruquinone F (-24.8521 kcal/mol). It can be inferred that Abruquinone D has a higher potential as an antibiotic (S. mutans) than Abruquinone F.
