Honey has natural bacteriostatic and bactericide activities; thus, it could be active compounds as an antibacterial against Propionibacterium acnes, the main bacteria in acne forming state. Our study aims to determine phenolic and flavonoid contents (qualitative and quantitative), antioxidants, along with antibacterial activity against P. acnes of selected Indonesian honey. Honey used in this study, including honeybees and stingless bees, were collected from Sumbawa, Riau, Belitung, Sukabumi, Banyuwangi, Bogor, and South Sulawesi. In the method, the quantitative content of phenols and flavonoid were measured using a spectrophotometer. Further, DPPH (2, 2’-diphenylpicryl hydrazyl) and ABTS (2’-azino-bis (3- ethylbenzothiazoline-6-sulfonic acid) assays were used to measure the antioxidant activities, and subsequently microdilution method was applied to determine antibacterial activity. The results showed that Indonesian honey contains phenolics and flavonoids in the range of 49.5-67.3 μg Gallic Acid Equivalent (GAE)/g and 766.5-1509.5 μg Quercetin Equivalent (QE)/g, respectively. All honey samples also show antioxidant and antibacterial activities. Of note, Apis cerana honey from Banyuwangi has the highest antioxidant and antibacterial activity compared to others. It has the Inhibition Concentration (IC50), Trolox Equivalent Antioxidant Capacity, Minimum Inhibitory Concentration (MIC) and Minimum Bactericide Concentration (MBC) values of 59.85 mg/L, 122 μg Trolox/g, 125 mg/mL, and 500 mg/mL respectively. Our study reveals that Indonesian honey can inhibit and kill P. acnes as well. Nonetheless, the phenolic content of honey is not always linear with antioxidant and antibacterial activities.

Jernang resin is secretion of jernang rattan (Daemonorops draco, Arecaceae family) fruits which is endemic in Southeast Asia. This resin has various biological activities and empirically used as wound healing, headache medicines, and fever remedies by Anak Dalam ethnic group from Jambi. This study was performed to evaluate the antioxidant activity of nonpolar fraction of D. draco resin which collected from Jambi Province, Sumatera, Indonesia. Resin was extracted with n-hexane, ethyl acetate, and methanol respectively. The antioxidant properties of the extracts were then evaluated using 1,1-diphenyl-2picryl-hidrazyl radical scavenging assay. The most active extract was further fractionated using n-hexane and methanol and separated using column chromatography and preparative thin layer chromatography. Separation of the extract was conducted through antioxidant assay-guided fractionation. Characterization of the active fraction was carried out by infrared spectroscopy. The result shows that ethyl acetate extract provides higher antioxidant activity (IC50 = 27.61 µg/mL) compare to methanol and n-hexane extracts. N-hexane fraction of ethyl acetate extract used for further separation using column and preparative thin layer chromatography due to its antioxidant activity. Separation using column chromatography resulting in 9 fractions (F.1-9). Fraction F.5 provide high antioxidant activity (IC50 = 17.27 µg/mL) and further separated using preparative thin layer chromatography resulting two fractions with lower antioxidant activity F.5.1 (IC50 = 85.18 µg/mL) and F.5.2 (IC50 = 34.94 µg/mL). Characterization of fraction F.5.2 using infrared spectroscopy showed that component in fraction F.5.2 contains NH-substituted benzene.

Jojoba (Simmondsia chinensis) (Link) C.K. is a shrub plant widely used in cosmetics, especially jojoba oil. The residue will remain when producing jojoba oil and become waste. This study aimed to determine the antibacterial activity of Jojoba seed residue (JSR) and its possible active antibacterial compounds. JSR was collected from Sudan and extracted by maceration with n-hexane, ethyl acetate, and 70% ethanol. The antibacterial activity was determined with the microdilution method against Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli). The 70% ethanol extract showed the value of MIC and MBC against E. coli, which was 7.8 mg/ml; meanwhile, against S. aureus was 3.9 mg/mL and 7.8 mg/mL, respectively. Fractionation of 70% ethanol extract using silica gel column chromatography with gradient elution produced ten fractions. Fraction 3 showed the MIC and MBC values in E. coli which were 3.1 mg/mL and 12 mg/ml, and in S. aureus, which were 3.1 mg/mL and 6.2 mg/mL. The fractionation continued to Fraction 3 using preparative thin layer chromatography to collect subfraction 3.2 at an Rf value of 0.76, actively based on contact autobiography against E. coli and S. aureus. Embelin was detected in Subfraction 3.2 using liquid chromatography-mass spectrometry (UHPLC-Q-Orbitrap HRMS) and suggested as the active antibacterial component in JSR.

The objective of this research was to determine the antioxidant and antiglycation activity of methanol crude extract of Xylocarpus granatum stem and its fraction. The methanol crude extract was fractioned by liquid-liquid extraction to obtain three fractions, which were n-hexane fraction, ethyl acetate fraction, and methanol fraction. Antioxidant activity was performed using scavenging 2,2-diphenyl-1-picrylhydrazyl (DPPH). The antiaging activity was identified based on the ability to inhibit the formation of advanced glycation end products (AGEs). The results of the study showed that methanol crude extract and all fractions had an antioxidant and antiglycation activity that significantly different from each other (P<0.05). The results show that the most active antiglycation and antioxidant activity was the methanol fraction with IC50 were 71.55 ppm and 8.52 ppm, respectively. The methanol fraction contained an alkaloid, flavonoid, phenolic, and triterpenoid compounds. Subsequent fractionation of the methanol fraction guided by bioassay showed that sub-fraction 1 had the best antiglycation and antioxidant activity. Based on the color of the chromatogram obtained at UV 366 nm, the chemical component contained in the most active fraction was the flavonoid group.

Phenolics, including flavonoids, are bioactive components in garlic in relatively abundant amounts and are present 2–4 times more in black garlic. Both of these compounds are reported to have biological activity, with one of them acting as an antioxidant. However, its ability as an antigout is still not widely reported. Xanthine oxidase, adenine deaminase, guanine deaminase, purine nucleoside phosphorylase, and 5-Nucleotidase II are involved during the production of uric acid and causes gout. This study predicted the potential of the phenolic and flavonoid compounds in garlic and black garlic as antigout in inhibiting five target receptors through a molecular docking approach. Utilizing AutoDock Tools v.1.5.7 for receptor and ligand preparation, AutoDock Vina and AutoDock4 for molecular docking, and LigPlot+ and PyMOL for visualization. About 21 compounds from the phenolic and flavonoid groups were used as test ligands and 16 reference ligands (substrate and commercial). SwissADME predicted the pharmacokinetic parameters. The results showed that apigenin, morin, resveratrol, kaempferol, (+)-catechin, isorhamnetin, and (-)-epicatechin were predicted to have good interactions at each target receptor and had the potential to be developed as candidates for multi-target antigout. Based on the pharmacokinetic parameters, all these compounds had good scores in each, making them feasible to continue in vitro or in vivo trials.

Melanin is a crucial amino acid in determining human skin and hair pigmentation. Excessive melanin production can lead to hyperpigmentation and darkening of the skin. This study aims to assess the capability of Adenostemma platyphyllum as a tyrosinase enzyme inhibitor. It predicts its anti-melanogenic activity through molecular docking with proteins involved in the melanogenesis process. The in-vitro approach was conducted by determining the tyrosinase enzyme inhibition capacity, while the in-silico approach involved ligand binding to target proteins from melanogenesis pathways. The highest tyrosinase inhibition capacity was observed in the ethanol extract, with values of 9.74 Kojic Acid Equivalent (KAE)/g extract (L-tyrosine) and 17.91 (KAE)/g extract (L-DOPA). Molecular docking analysis showed that the binding of eriodictyol 7-O-sophoroside (ΔG = -9.7 kcal/mol) has the best energy affinity for the PKC-β protein, genistein (ΔG = -7.5 kcal/mol) for the tyrosinase-related protein-1 (TYRP1) protein, eriodictyol 7-O-sophoroside (ΔG = -10.2 kcal/mol) for the cGMP protein, vincosamide (ΔG = -7.2 kcal/mol) for the microphthalmia-associated transcription factor (MITF) protein, and dicaffeoylquinic acid (ΔG = -7.4 kcal/mol) for the β-catenin protein. Based on a comparison of in-vitro and in-silico studies, melanogenesis inhibition is more potent in the PKC-β and cGMP pathways than direct tyrosinase inhibition because they exhibit lower binding energy.

Iron contamination in water is a threat to human health and the environment. This contamination requires a fast and efficient detection method. Method validation is integral to method development, ensuring alignment with the intended objectives. This research aims to validate a method for selective detection of Fe(III) based on cellulose triacetate (CTA) optode membrane. The optode membrane was prepared by mixing CTA, plasticizers, Aliquat-336, and thiocyanate as selective reagents. The validation of the optode membrane was evaluated based on validation performance parameters. The Fe(III) optode membrane detection demonstrated a linear response with a determination coefficient of 0.9972 within a concentration range of 0.1–4.0 mg/L, the detection limit of 0.0553 mg/L, quantitation limit of 0.1676 mg/L, precision 3.01%, intermediate precision of 3.03% and 3.01%, the accuracy of 101.62%. The optode membrane exhibited good selectivity with a value of -0.4580 and -0.2748 against Pb(II) and Cr(VI), respectively, sensitivity of 1.05 × 107 M-1 cm-1 and color formation stability %RSD of 3.14%. The application of real samples shows no significant difference between the UV-Vis spectrophotometry and optode membrane methods at a 95% confidence level (α = 0.05). The validation results offer a valuable perspective into whether this method can be adopted as a new approach or as an alternative to existing methods for cation analysis in water samples.

Indonesia has long been known as a tropical country rich in various local cultivars of rambutan (Nephelium lappaceum L.), including Aceh Lebak (AL), Aceh Pelat (AP), Binjai (B), Gula Batu (GB), and Sikoneng (SK). Due to their phenolic and flavonoid compound, rambutan peel extracts have been reported to exhibit antioxidant and antiproliferative properties. Variation among cultivars suggests potential differences in bioactive compound content and biological activity. The objective of this study was to evaluate the antioxidant and toxicity profiles of five rambutan peel varieties and their correlation with total phenolic compound (TPC) and total flavonoid content (TFC). The antioxidant activity was evaluated using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) method, and phenolic and flavonoid contents were measured by colorimetric assays. Toxicity was assessed using the Brine Shrimp Lethality Test (BSLT). Bioautography analysis using TLC-DPPH was conducted to identify antioxidant-active compounds. In this study, all rambutan peel extracts indicated the presence of flavonoids, phenolics, saponins, steroids, alkaloids, and triterpenoids. The highest extract yield was observed in Sikoneng, also with the highest TPC and TFC values. The Binjai variety exhibited strong antioxidant activity (IC50 = 4.73 ± 0.19 mg/L) and three active antioxidant spots; however, it also exhibited toxicity (LC50 = 136.27 ± 6.58 mg/L). The correlation between total phenolic or flavonoid content and the observed biological activity was not statistically significant, indicating that additional metabolites or synergistic interactions may also contribute. These findings underscore the significant impact of biodiversity on differences in compound levels and potential biological activities among rambutan peel varieties.
