Pacar air (Impatiens balsamina L.) plant belongs to the Balsaminaceae family and is used as an indigenous medicine in Asia for fingernail inflammation, fractures, and rheumatism treatments. Moreover, the antipruritic, antianaphylactic, antifungal, antibacterial, and antitumor activities of some compounds, especially phenolics and quinones from this plant have been studied extensively. Therefore, this study aims to determine the antifungal activity of Pacar air leaves (Impatiens balsamina L.) methanol extract against Rhizopus oryzae L. and the IC50 value. The results showed that an increase in the concentrations of I. balsamina L. leaves methanol extract significantly raised the fungal growth. Furthermore, the extract inhibition against R. oryzae L. at various concentrations of 0.5; 0.7; 0.9; 1.1; and 1.3% w/v were 10, 21.9, 58.06, 68.06, and 79.72%, respectively, while the IC50 value was 0.896%. Hence, the presence of naphthoquinones and other secondary metabolites are responsible for its antifungal activity. Based on these results, the antifungal potential of I. balsamina L. leaves against soft-rot fungi is useful in the future.

Pada penelitian ini, nanopartikel emas disiapkan melalui pendekatan green synthesis menggunakan ekstrak air bunga tapak kuda (Ipomoea pescaprae L. Sweet). Nanopartikel emas yang dihasilkan dianalisis menggunakan spektrofotometer UV-Vis, Mikroskop Leica, Particle Size Analyzer (PSA), Spektrofotometer Fourier Transform Infra-Red (FTIR) dan X-ray Difractometer (XRD). Hasil pengukuran PSA menunjukkan ukuran partikel terbaik, diperoleh dengan menggunakan perbandingan volume 1 mL larutan HAuCl4 dengan 9 mL ekstrak yang menghasilkan partikel dengan ukuran rata-rata 16,3 nm. Hasil penampakan dengan mikroskop cahaya, memperlihatkan partikel berbentuk bulat. Pergeseran bilangan gelombang pada spektrum infra-merah menunjukkan adanya interaksi antara metabolit sekunder dari ekstrak dengan material emas. Analisis XRD menunjukkan bahwa nanopartikel emas telah dapat dihasilkan dari kondisi reaksi ini.

Cerium (IV) oxide or ceria (CeO2) was fabricated by heating an aqueous extract of Garcinia mangostana and cerium (III) nitrate in hydrothermal autoclave reactor at 200 °C for 3 hours, followed by calcination at 600 °C for 5 hours. The powder X-ray diffraction (XRD) pattern of the precipitate from cerium(III) nitrate under hydrothermal reaction conditions shows no clear XRD peaks, indicating its amorphous nature. In contrast, the products from the calcinated samples exhibit XRD peaks, which correspond to cubic fluorite structure with an average crystal size of 7.55 nm. The elemental mapping using the energy-dispersive X-ray (EDX) analysis reveals the main elements present were cerium and oxygen, with minor impurities in low amounts. The presence of Garcinia mangostana extract is predicted to be the key component and fuel source to obtain CeO2 particles with narrow crystal size.

In this study, we developed an alternative of 4-nitrophenol reduction mediated by silver nanoparticles (AgNPs) which was synthesized using aqueous extract of the Peronema canescens leaf through an eco-friendly approach. The reducing 4-nitrophenol to 4-aminophenol mediated by AgNPS in the presence of sodium borohydride as a hydrogen source proceeded rapidly at room temperature without any additional treatments. The AgNPS synthesis was simple and was carried out under mild conditions. Ultraviolet–visible spectroscopy was performed to examine the properties of the obtained AgNPs, which displayed an absorption peak at 431 nm. A transmission electron microscopy analysis revealed that the AgNPs were spherical in shape and had an average particle size of 19 nm as determined by particle size analysis.

A new synthetic procedure is described for the synthesis of calcium silicate derivatives, using natural resources such as eggshell (ES) for calcium and oil palm leaves (OPL) for silica, which do not require prepurification. The reaction is performed by directly converting two weight ratio of the precursors, ES:3OPL and ES:6OPL, to dried-powder form by heat treatment at 900 °C for two hours. The results demonstrate that the concentration of the precursors has an effect on the morphology and crystallinity of the calcium silicate derivatives, mainly Ca2SiO4 and CaSiO3. X-ray diffraction results reveal that the reaction product obtained using a 1:3 ratio is quite pure, and mainly consisted of calcium silicate in the form of Ca2SiO4. The CaSiO3 was also identified in ES:6OPL, together with a small amount of excess non-reacted crystalline silica. Furthermore, a scanning electron microscopy analysis shows that both reaction products have a coarse surface. Copyright © 2020 by Authors, Published by BCREC Group.

Melastoma malabathricum Fruit Extract-Mediated Synthesis of Silver Nanoparticles with Sensing Ability for High Concentrations of Mercury (II) Nitrate SALPRIMA YUDHA S; Aswin Falahudin; Meka Saima Perdani; Irfan Gustian; Saiqa Ikram

A strategic approach was developed to synthesize silver nanoparticles from AgNO3 using Melastoma malabathricum seed extract. The reaction of silver ions with the organic compounds in the seed extract proceeded smoothly at room temperature without any additional capping agent. The appearance of an absorption peak around 427 nm provided evidence for the presence of silver nanoparticles in the reaction mixture. A diluted solution of the silver nanoparticles was treated with various concentrations of mercury (II) nitrate solutions and the resulting reaction was monitored using UV-Vis spectrophotometry

Light-induced synthesis of micron-sized metallic silver in aqueous extract of Rivina humilis L. fruits and its interaction with Corptotermes curvignathus Salprima Yudha S; Aswin Falahudin; Morina Adfa; Irfan Gustian; Herlina Herlina

The aqueous extract of Rivina humilis was suitable to reduce silver ions (Ag+) to form micron-sized metallic silver at room temperature and without any addition of external reducing agent or stabilizer compounds. The reduction process was assisted by light, indicated by the colour change of the reaction mixture and supported by the appearance of peak at 455 nm in spectrophotometric analysis when the reaction was carried out under room light. Based on transmission electron microscopy (TEM) analysis, the as-prepared metallic silver was in spherical form. The analysis results using particles size analyzer (PSA) show their particles distribution from micro to nano size (average size was 199 nm). The interaction behaviour of micron-sized metallic silver/extract solution with Corptotermes curvignathus termites shows that the silver gives small additional effects along with the activity of the extract.

IRON CHELATING AND ANTIRADICAL ACTIVITY OF KAYU MANIK LEAVES (Trema orientalis) Salprima Yudha S.; Eka Angasa; Sri Ningsih; Syalfinaf Manaf; Suli Anggria Murni; Fatan Umbara

A methanol soluble fraction extracted from Kayu Manik leaves (Trema orientalis) from Seluma, Bengkulu, exhibited an antiradical activity 69.73% (scavenging activity of the stable 1,1-diphenyl-2-picryl hydrazyl (DPPH) free radical) that was almost similar to that of 1 mM ascorbic acid. On the other hand, the iron chelating activity was 40.74%. We believe that it would be useful to take the results as an alternative for processing industries and can be observed as a good source of new agent for iron chelator.

The main focus of this research is to ascertain the X-ray diffraction (XRD) pattern, Fourier transform infrared (FTIR) spectroscopic pattern, and surface morphology of a hornet (Vespa affinis) nest. The optical microscopic(OM) analysis demonstrated that the nest presented an irregular formation of partition materials. This was confirmed via scanning electron microscopy (SEM), which revealed the presence of a unique form with a honeycomb-like pattern. Meanwhile, the materials largely consisted of carbon and oxygen elements, as was revealed by the energy dispersive X-ray (EDX) analysis, while the XRD analysis indicated that the nest was composed of amorphous materials of cellulose and lignin. Finally, the (FTIR) spectroscopy analysis revealed the presence of a number of peaks, which indicated that the material also consisted of a mixture of cellulose, hemicellulose, and lignin materials. It is envisaged that these results would widen the possibilities of fundamental scientific research on forest products, particularly the use of the V. affinis nest for further biological and chemical research.
