“…Sedangkan uji kualitatif flavonoid memberikan warna jingga atau merah atau kuning kecoklatan dengan menambahkan larutan Mg dan HCl. Dengan penambahan HCl akan terjadi reaksi oksidasi reduksi antara logam Mg sebagai pereduksi dengan senyawa flavonoid (Rachmawati and Suriawati, 2019).…”

Daun kelor banyak dibudidayakan oleh masyarakat karena diyakini dapat memberikan banyak manfaat, antara lain bidang farmasi dan makanan. Ekstrak daun kelor (Moringa oleifera L.) mengandung senyawa alkaloid, flavonoid, fenolat, triterpenoida/steroida, dan tanin yang berfungsi sebagai antioksidan. Senyawa zat aktif pada daun kelor dapat diperoleh dengan cara ekstraksi menggunakan pelarut air, karena pelarut air dapat diaplikasikan ke masyarakat sebagai sediaan yang aman untuk dikonsumsi. Umumnya penelitian ekstrak daun kelor menggunakan pelarut air dengan cara infusa atau pelarut organik. Penelitian ekstrak daun kelor yang diperoleh dengan cara pemerasan belum pernah dilakukan, terutama aktivitas antioksidan. Tujuan dari penelitian adalah untuk mengetahui aktivitas antioksidan ekstrak daun kelor dengan metode DPPH dan FRAP sebagai sediaan obat dan makanan. Uji aktivitas antioksidan dilakukan dengan metode 2,2-difenil-I-pikrilhidrazil/DPPH serta metode aktivitas potensial reduksi besi (Ferric Reduction Antioxidant Power/FRAP) yang masing masing memiliki kelebihan pada metodenya. Hasil penelitian ekstrak daun kelor infusa dan pemerasan memiliki kadar fenol total 50,10331±0,005 mg GAE/g dan 47,55012±0,019 mg GAE/g sedangkan kadar flavonoid total 36,56286±0,026 mg QE/g dan 37,76643±0,025 mg QE/g. IC50 ekstrak daun kelor infusa dan pemerasan dengan metode DPPH sebesar 4,12 ppm dan 26,13 ppm serta IC50 ekstrak daun kelor infusa dan pemerasan dengan metode FRAP adalah 11140,06 ppm dan 21529,00 ppm. Berdasarkan hasil tersebut dapat disimpulkan ekstrak daun kelor dengan metode DPPH memiliki aktivitas antioksidan kuat dan metode FRAP memiliki aktivitas antioksidan lemah, sehingga ekstrak daun kelor tersebut dapat digunakan sebagai sediaan obat dan makanan.

“…M. oleifera leaves have active compounds as antibacterial and, at the same time, shows that M. oleifera leaves have high potential as antibiotics. Rachmawati & Suriawati, (2019) in their research using the boiling method, stated that M. oleifera leaf extract contains flavonoids, triterpenoids, steroids, saponins, and tannins. These are antimicrobial compounds (Seyydnejad et al 2010;Sariwati et al 2019).…”

The Moringa oleifera can be used as a medium for the prevention and treatment of infectious diseases such as diarrhea. Diarrhea can be caused by Escherichia coli, which house flies can transmit. Moringa oleifera leaves have antimicrobial substances such as flavonoids, triterpenoids, steroids, saponins and tannins. This aim of the study was to determine the minimum inhibitory concentration of M. oleifera infusion on the growth of E. coli. This research is a laboratory experiment with Well Diffusion Agar method and dilution technique. The materials used in the study were M. oleifera leaf infusion with concentrations of 50%, 40%, 30%, 20%, and 10%, while 0% was a negative control (Aquadest). E. coli isolates were obtained from M. domestica. The results showed that the inhibition zone formed at concentrations of 50%, 40%, 30%, 20%, 10%, and 0% was 15.55 mm, 13.80 mm, 13.10 mm, 10.10 mm, and 0 mm, respectively. The minimum inhibitory concentration of leaf infusion against E. coli isolates was 25%, and the minimum bactericidal concentration could not be determined because all concentrations tested showed bacterial growth. Instead, the lowest inhibitory concentration was 25%. In concentrations of 50%, 40%, and 30%, M. oleifera leaf infusion has potent antibacterial action; at concentrations of 20%, it has moderate antimicrobial activity; and at concentrations of 10%, it is unable to inhibit the growth of E. coli. Further research is needed to determine the value of the minimum bactericidal concentration at concentrations above 25%, and it is necessary to test it on other digestive tract pathogenic bacteria.

“…Types of plants contain compounds metabolites, including proteins, enzymes, phenols, amines, alkaloids, flavonoids, terpenoids, and pigments, which can play roles as agent reducers and stabilizers (Rachmawati & Suriawati, 2019). Agent reducer plays a role in secondary metabolite compounds in biological organisms that will reduce Zn 2+ ions to ZnO.…”

“…The active compounds in Moringa are found in many parts of the leaves. Compound active contained in leaf Moringa, namely flavonoids, saponins, alkaloids, and phenols, role as agent reducers and stabilizers in the formation of nanoparticles ZnO (Rachmawati & Suriawati, 2019). The use of Moringa leaves is still limited primarily to the household scale.…”

This research was conducted to determine the effect of varying concentrations of Zn(NO3)2·6H2O (zinc nitrate hexahydrate) on functional groups, particle size, and particle morphology of ZnO nanoparticles using the green synthesis method using Moringa leaves. The materials was used in this study were moringa leaf extract, Zn(NO3)2·6H2O with various concentrations of 0.2, 0.4, 0.6, and 0.8 M, and NaOH of 0.1 M. Based on the results of characterization using FTIR, it shows that the functional groups in the content of Moringa leaves play a role in the formation of ZnO nanoparticles. Meanwhile, the results of the XRD characterization showed a diffractogram difference with standard ZnO at concentrations of 0.6 M and 0.8 M Zn(NO3)2·6H2O with the appearance of the NaNO3 phase. SEM characterization results show that the morphology of ZnO nanoparticles using the green synthesis method is irregular in shape.
