Abstract: Abstract. Sibero MT, Siswanto AP, Frederick EH, Wijaya AP, Syafitri E, Farabi K, Murwani R, Saito S, Igaras Y. 2020. Antibacterial, cytotoxicity and metabolite profiling of crude methanolic extract from andaliman (Zanthoxylum acanthopodium) fruit. Bio ersitas 21: 4147-4154. The local community in North Sumatra has utilized andaliman fruit (Zanthoxylum acanthopodium) as spices for traditional cuisines because it has a unique flavor. Information on the antimicrobial activity of Z. acanthopodium fruit against aquaculture pathogens and its bioactivity against leukemia cell lines are limited. The purposes of this study were to evaluate the antimicrobial activity of Z. acanthopodium fruit against Tenacibaculum maritimum, Vibrio alginolyticus, V. anguillarum, V. harveyi that are known as pathogens in aquaculture to determine cytotoxic property against murine P388 leukemia cells and to characterize its metabolites profile. The s le was extracted using methanol by the maceration method. Antibacterial assay was conducted by Kirby-Bauer disc diffusion method while cytotoxicity assay using the XTT method. Proximate analysis showed that Z. acanthopodium fruit contained 63.41% of moisture, 24.73% of crude fiber, 9.81% of crude protein, 6.90% of ash, and 2.55% of crude fat. Several phytochemical components were detected, such as alkaloid, flavonoid, tannin, triterpenoid, and steroid. The GC/MS analysis indicated the presence of various compounds from terpenoid and terpenes derivatives. This study indicated that Z. acanthopodium fruit was not potential as antibacterial agents against the aquaculture pathogens however, the methanol extract showed cytotoxic potential with IC50 19.14 µg/mL against murine P388 leukemia cells.

Abstract: Flavonoids are a secondary metabolite group with various bioactivities, such as antioxidants. They are rich in the genus Erythrina, such as Erythrina crista-galli. This research aims to isolate and characterize flavonoids from the twigs of E. crista-galli and determine their antioxidant properties through in silico and in vitro assays. The ethyl acetate extract of E. crista-galli twigs were separated by column chromatography and characterized using spectroscopic methods. Density functional theory (DFT) calculations were performed on the isolated flavonoids and the reference compounds (ascorbic acid and quercetin) to obtain global descriptive parameters and a donor–acceptor map (DAM). We successfully isolated lupinifolin (1) and citflavanone (2) for the first time from E. crista-galli, along with lonchocarpol A (3), which has been discovered previously. The DAM suggests that these flavanones are good antiradicals with effective electron donors. However, they tend to be electron acceptors in methanol. The frontier molecular orbital analysis implies that lupinifolin (1) is a better antiradical than the other flavanones. The DPPH assays show that lupinifolin (1) has the highest antioxidant (antiradical) activity, with an IC50 value of 128.64 ppm. The in silico studies showed similar trends to the in vitro assays using the DPPH method.
