Abstract

Fungus comb is a structure made by termite colony Macrotermitinae with lots of potential because it contains secondary metabolites such as steroids, terpenoids, and saponins and compounds containing antioxidant and anti-tyrosinase properties. This study aimed to determine fungus comb extracts' fingerprint pattern, antioxidant capacity, and anti-tyrosinase activity. Thin layer chromatography (TLC) was used to determine fingerprint patterns. The resulting TLC pattern was processed with ImageJ and converted into a densitogram. The fungus comb was extracted with n-hexane and ethyl acetate. TLC results showed that fungus comb extracts contain steroids and terpenoids and have antioxidant properties. The antioxidant capacity assay was carried out with 2,2-diphenyl-1-picrylhydrazyl reagent. N-hexane extract had an antioxidant capacity value of 9.07 mg ascorbic acid equivalent (AAE)/g extract, while ethyl acetate extract had 6.04 mg AAE/g extract. Anti-tyrosinase activity assay was carried out with L-tyrosine and L-3,4-dihydroxyphenylalanine (L-DOPA) as substrates. N-hexane extract had a better anti-tyrosinase activity with IC50 of 1804 µg/mL for L-tyrosine and 6784 µg/mL for L-DOPA.

Abstract

Some Asteraceae plants are reported to contain phytochemicals and to show high antibacterial activity. This study aims to determine the highest antibacterial activity of Wedelia trilobata, Acmella paniculata, Ageratum conyzoides, and Crassocephalum crepidiodes and to predict the chemical compounds that have a role as antibacterial. The samples were extracted with water and further fractionated using chloroform in the laboratory. Extracts determined the phytochemical compounds, antibacterial activity diffusion method, and compounds that have a role as antibacterial through literature review. Acmella paniculata demonstrated high antibacterial activities with the highest diameter of the zones of inhibition with a concentration of just 0.5 mg/disc. The compound that seems to have a role in antibacterial activity is spilanthol.

Abstract

Stroke due to cerebral ischemia is one of the leading causes of disability worldwide. Animal models of cerebral ischemia that is often used is Global Cerebral Ischemia (GCI). In GCI, the hippocampus is the most susceptible to neuronal cell death. Complications that occur after ischemia are due to increased oxidative stress. Some compounds in purwoceng are reported to have antioxidant activity which oxidative stress have not been studied in the GCI model stroke. This study aims to examine the effect of purwoceng extract on a stroke model (GCI) as a neuroprotective agent in the prevention of stroke complications that have not been previously studied. 25 rats with a stroke model were given purwoceng root extract with 3 doses (20, 30, and 40mg/kg BW) orally for three days. The mice were then tested for memory with the Morriz Water Maze (MWM) test; then histopathological analysis of pyramidal cells in the hippocampus and the expression of SOD1 and SOD2 genes was analyzed using RT-PCR. The MWM test showed that the memory results at the dose of 20mg/kg BW were better than that of the GCI group (p=0.0384), and the PCR of SOD2 showed improvement at the dose of 20mg/kg BW (p=0.0171). No significant difference in histopathological analysis and SOD1 mRNA expression across group. The administration of purwoceng root extract at a dose of 20 mg/kg BW had the effect of improving memory and SOD2 expression in GCI model rats

Abstract

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.

Abstract

ABSTRACT. The Lamiaceae family which are widely used in traditional medicine in Indonesia. Plants from this family are known to have antioxidant bioactivity. Therefore, in this study, an antioxidant test was carried out first as an initial screening. This study evaluated the antioxidant capacity of four Lamiaceae species: Ocimum americanum L., Ocimum basilicum L., Leucas lavandulifolia Sm., and Perilla frutescens (L.) Britton. The four Lamiaceae species extracts were evaluated for their antioxidant capacity using 2,2-diphenyl-1-picrylhydrazyl (DPPH), cupric-reducing antioxidant capacity (CUPRAC), and ferric-reducing antioxidant power (FRAP). The highest activity extract was fractionated with n-hexane, ethyl acetate, and ethanol-water, and the results were tested for antioxidant capacity. The most active extract and most active fraction were analyzed for metabolites using liquid chromatography-mass spectrometry (LC-MS/MS). The results show that the ethanol 50% leaves extracts of O. americanum L. have the highest antioxidant capacity of about 0.439 (DPPH); 1.517 (CUPRAC); and 1.021 (FRAP) mmol ascorbic acid equivalent (AAE)/g extract. The highest antioxidant capacity from the partition results was possessed by the ethyl acetate fraction with a value of 1.109 (DPPH); 1.540 (CUPRAC); and 1.551 (FRAP) mmol AAE/g fraction. Metabolite analysis using LC-MS/MS succeeded in identifying 18 metabolites consisting of flavonoids, terpenoids, amino acids, phenolic acids, fatty acids, and other carboxylic acids.

Abstract

Strobilanthes crispa known as keji beling in Indonesia, belong to the Acanthaceae family. Thin layer chromatography (TLC) fingerprint pattern analysis is an excellent technique for evaluating and controlling the quality of raw materials containing Strobilanthes crispa. TLC fingerprints can be used to analyze the fingerprint profiles of medicinal plants for identification, authentication, and discrimination from related plants. This study aimed to develop a TLC fingerprint analysis method to identify S. crispa for quality control. Eleven bands were effectively separated using a silica gel 60 F254 TLC plate with a mobile phase of dichloromethane, ethyl acetate, and chloroform at 16:3.2:0.8. The derivatization reagent used to detect the separated bands was 10% sulfuric acid at a wavelength of 366 nm. Validation of the TLC fingerprint analysis, which evaluated the robustness, stability, specificity, and precision, met these requirements. S. crispa can be distinguished by its TLC fingerprint from sirih hutan (Piper aduncum), a related plant with similar leaf morphology. This approach could be used to identify and authenticate of S. crispa from P. aduncum.

Abstract

Identifying floral resources used by honey bees and stingless bees is essential for sustainable beekeeping and understanding pollination ecology. This study compared the diversity of floral resources utilized by the honey bee Apis cerana and stingless bees Geniotrigona thoracica and Heterotrigona itama based on pollen in honey. Bee colonies were in the same Flora Nauli Beekeeping area, Pematang Siantar, North Sumatra, Indonesia, ensuring equal access to similar surrounding floral resources. Honey samples were collected, and pollen grains were extracted, acetolysed, and analyzed by counting 1,200 grains to determine frequency classes. Pollen diversity was calculated using the Shannon–Wiener index (H′). Stingless bee honey contained more diverse pollen than A. cerana, which only contained pollen from the Arecaceae family. Heterotrigona itama and G. thoracica honey contained pollen from 20 and 11 plant families, respectively. Each species had a distinct predominant pollen type (>45%): Cocos nucifera (A. cerana), Sapotaceae type (G. thoracica), and Casuarinaceae type (H. itama). A higher pollen diversity index was also observed in H. itama (1.05-1.83) than in G. thoracica (0.34–1.64) and A. cerana (0.66). These results indicate that stingless bees are more generalist than honey bees, highlighting their ecological role in supporting pollination networks in tropical agroecosystems.
