Abstract

Java turmeric (Curcuma xanthoriza) is one of the native plants from Indonesia. Java turmeric is known as a medicinal plant with a high content of volatile oils. In this study, we investigated the chemical profile of java turmeric essential oil obtained by hydrodistillation associated with different harvesting times of the rhizome (7, 9, and 11 months). The constituent of the essential oil was determined by using gas chromatography-mass spectrometer. About 19, 20 and 34 compounds were identified in 7, 9, and 11-month old java turmeric. Fifteen compounds were found in all samples namely β-elemene, zingiberene, γ-elemene, β-farnesene, α-curcumene, benzofuran, α-cedrene, epicurzerenone, ar-curcumene, germacrone, aromadendrene, α–longipene, trans-caryophilene, curcuphenol, and xanthorrhizol. This study showed the level of all compound detected in 7, 9, and 11 months old of java turmeric is different.

Abstract

In solid-phase extraction for preconcentration, silica (Si) is the most commonly used as an adsorbent. However, the selectivity and effectiveness of silica gel adsorption on metal ions are low, so it needs to be modified to improve the adsorption capability. The modification was done using reflux and oven heating in the modification silica with 3-glycidoxypropyl trimethoxysilane (GPTMS) and tetraethylene glycol (TEG). A central composite design batch process determined the optimum conditions for cadmium adsorption. TEG-modified silica was successfully synthesized and characterized using FTIR spectroscopy, SEM, and elemental analyzers. Peaks of C-H and epoxy on FTIR spectra showed that Si- GPTMS was formed. The increase of %C and %H from the first to the second step indicated that Si-TEG was successfully synthesized. There was no significant difference in silica particle morphology on SEM before and after modification. The reflux method gave a higher yield compared to the heating method. The constant stirring by the magnetic bar and solvent cycle in the reflux method catalyzed the reaction. This study found that at pH 7, 30 mg of adsorbent weight at 35°C and 22 minutes of contact time were optimum Cd2+ adsorption conditions. As the weight of the adsorbent increases, the adsorption capacity decreases. Contact time and temperature have no significant effect on Cd adsorption by Si-TEG.

Abstract

Thin layer chromatography (TLC) fingerprint profile analysis can be used for quality control of herbal medicinal raw materials through identification, authentication, and discrimination. This study aims to develop a fingerprint analysis method for tempuyung TLC (Sonchus arvensis L.), which is then used for quality control. Tempuyung was extracted with methanol using ultrasonication which was then analyzed using the developed fingerprint TLC method. The optimum mobile phase used to separate compounds from tempuyung was a composition of chloroform: ethyl acetate: dichloromethane: formic acid (7.5:2:0.5:0.1) and produced eleven bands. The mobile phase composition produced good separation and had a typical luteolin band with an Rf value of 0.22, detected under UV 366 nm and derivatized with 10% sulfuric acid reagent. This method was applied to tempuyung from three locations, including Malang, Solo, and Yogyakarta, whose fingerprint patterns did not differ significantly. The fingerprint method has been validated and met the acceptance requirements for quality control of tempuyung.

Abstract

Sidaguri (Sida rhombifolia) belongs to the family Malvaceae and is used in traditional medicine to treat skindiseases, diarrhea, malaria, fever, and gout. These activities are caused by the presence of bioactivemetabolites, such as alkaloids, flavonoids, steroids, tannins, and saponins. Several factors, including harvestage, could affect the metabolite composition and concentration in a plant. In this study, the TLC fingerprint ofS. rhombifolia at planting ages of 3, 4, and 5 months was determined and in vitro xanthine oxidase inhibitoryactivity was evaluated. The TLC fingerprints obtained from the three planting ages had similar patterns. Thereare 11 compound bands with different color intensities at each planting age. Principal component analysis candifferentiate S. rhombifolia by planting age using TLC fingerprint analysis, with a total PC of 99%. The resultsof xanthine oxidase inhibition showed that the S. rhombifolia ethanol extract at 3, 4, and 5 months of plantingage inhibited the enzyme activity, with percent inhibitions of 45.37%, 44.72%, and 6.87%, respectively, at aconcentration of 100 ppm. Different planting ages of sidaguri are thought to contain varying concentrationsof compounds, as indicated by TLC fingerprints, and to result in different levels of xanthine oxidase inhibition.

Abstract

Research on microplastic (MP) accumulation in marine organisms' tissue have been widely conducted, as well as research on microplastic biodegradation by microbial organisms from the environment.Agelas coniferasponge is proven to accumulate MP in its tissue as well as having bacteria as symbiotic organism. This research aims to screen and study biodegradation activities ofA. coniferasymbiotic bacteria on MP polymers, alsoto identify the species of those bacteria isolates. Bacterial Isolation ofA. coniferasponge tissue was using Zobell 2216E agar media. Screening and biodegradation assay of the bacteria isolates was conducted on Marine Salt Media agar that was added with 0,5 g of MP polymers, using Kroc-Boral method. Diameter of clear (bacterial growth) zone surrounding Kroc-Boral indicated the biodegradation activity of the bacterial isolates. Statistical analysis on the activity was using Two Way ANOVA. Results showed that there were 9 bacterial isolates of 53 that could degrade several MP polymers, with different activities (ANOVA, p value 0.05). High and low-density polymers (Linear- Low Density PolyEthylene/ LLDPE, Polyethylene/PE, and Polyvinyl Chloride/ PVC) were found to be degraded by all 9 isolates. Meanwhile, Polyethylen Taraphtalene (PET) and Polystyrene (PS) only degraded by 8 and 3 isolates, respectively. There are only 5 isolates that have high biodegradation index (1.5) on different polymers, which mostly on PET polymer. Isolate Ac8MP found to be the most bacteria that have degradation index on all polymers more than 1.This research proves that symbiotic bacteria could have a biodegradation mechanism on MP polymers that accumulates by sponge-host. However, further study needs to be done to understand the mechanisms and effectiveness of sponge-bacterial biodegradation activity.

Abstract. Rafi M, Septaningsih DA, Karomah AH, Lukman, Prajogo B, Amran MB, Rohman A. 2021. Inhibition of ?-glucosidase activity, metals content, and phytochemical profiling of Andrographis paniculata from different geographical origins based on FTIR and UHPLC-Q-Orbitrap HRMS metabolomics. Biodiversitas 22: 1535-1542. Ensuring consistency of quality, safety, and efficacy of herbal medicines from raw materials to finished products is important because of the variability in medicinal plants' active components. One of the plants that have been used as an antidiabetic herbal medicine is A. paniculata. This study aims to determine ?-glucosidase inhibitory activity, the content of several metals, FTIR spectrum profile, and putative identification of A. paniculata metabolites using UHPLC-Q-Orbitrap HRMS from different geographical origin. We found that ethanol extract of A. paniculata gave higher inhibition of ?-glucosidase activity compared to water extract. Eight metals were determined using FAAS and FAES, and calcium showed the highest content in all A. paniculata samples. FTIR spectra of A. paniculata showed a similar profile and only differed in the absorbance. We detected the presence of OH, C=O, C=C aromatic, and C-O functional groups in A. paniculata extract. About 32 metabolites were putatively identified in A. paniculata, mainly from phenolic and diterpene lactones class compounds based on UHPLC-Q-Orbitrap HRMS. Using a combination of FTIR spectra and peak area from 32 identified peaks, we can clustered A. paniculata based on its geographical origin. Based on the result obtained, the geographical origin of A. paniculata affected the metals and metabolites composition and level, resulting in different levels of ?-glucosidase inhibitory activity.

Abstract. Marliani N, Artika IM, Rafi M, Syukur M, Galingging RY, Nurcholis W. 2022. Phenolic and flavonoid content with agro morphological characters of 12 accessions of Justica gendarussa grew in Indonesia. Biodiversitas 23: 5101-5107. Justicia gendarussa Burm. f is a medicinal plant used in traditional and modern medicine. This study was conducted to determine the agro morphological characters, phenolic and flavonoid content of 12 accessions of J. gendarussa plants obtained from various locations in Indonesia and then grown in the same conditions and places. The agro morphological characteristics include plant height, number of leaves, number of branches, wet weight, and dry weight of leaves and stems. Total phenolic content (TPC) and total flavonoid content (TFC) were analyzed by spectrophotometric method. The results showed significant differences in the characters of 12 accessions of J. gendarussa (p<0.05). Accessions of BK4 (Bekasi 4) and KP (Kejayan Pasuruan) had the best agro morphological characteristics. Accessions of BK4 (Bekasi 4) and BG (Bogor) had the best growth rates. The highest TPC value was obtained from TG (Trenggalek) accession (0.752 mg GAE/g DW) and the highest TFC (1.899 mg QE/g DW from LK (Langkat) accession. The best accessions based on agro morphological characters were BK4 (Bekasi 4) and KP (Kejayan Pasuruan), and based on the content of polyphenols were TG (Trenggalek) and LK (Langkat). The accessions of BK4, BG, TG, and LK could be further developed into superior varieties of J. gendarussa.

Abstract. Raisawati T, Melati M, Aziz SA, Rafi M. 2023. Harvest methods determine the yield and quality of Sonchus arvensis accessions cultivated in organic way. Biodiversitas 24: 4110-4119. Sowthistle (Sonchus arvensisL.) is a wild plant species with high potential for medicinal uses. Nonetheless, the understanding of agronomical aspect of this species is still limited, hindering the large-scale cultivation efforts. This species has unique traits in term of leaves morphology in which it has rosette (old) leaves and upper (inflorescence) leaves which might require particular harvesting method to obtain optimal yield and quality. This study aimed to evaluate the effect of harvest methods on leaf production, total flavonoid content, antioxidant activity and flavonoid profiles of three accessions of sowthistle. The experiment used randomized complete block design with three replications. The first factor is harvesting methods namely gradual and simultaneous harvest of lower and upper leaves of sowthistle. The second factor is three accessions of S. arvensis namely Lembang, Tawangmangu, and Banjararum. The results showed that the simultaneous harvest resulted in higherleaf number by 65%, fresh weight by 55%, and dry weight by 60% compared to those of gradual harvest. However, the difference between fresh weight and dry weight of upper leaf was more determined by the accessions with Tawangmangu had the highest weight. Antioxidant activity of sowthistle in this study is not only caused by total flavonoid. Tawangmangu accession gradually harvested produced high lower leaf antioxidants, while those harvested simultaneously produced the highest total flavonoid contents and antioxidant activity of upper leaves. The results of HPLC analysis showed the flavonoid profiles of S. arvensis leaves which contain rutin, myricetin, luteolin, quercetin, kaempferol and apigenin. Kaempferol was the highest content of flavonoid in rosette and upper leaves. The findings of this study suggest that simultaneous harvesting is recommended to obtain high sowthistle production and quality.

Abstract

Kaempferol, a widely distributed natural flavonoid, is increasingly studied for its antidiabetic properties. However, a comprehensive bibliometric analysis mapping the global research landscape of this field is currently lacking. This study aims to map research trends, collaborations, and the thematic evolution of kaempferol in diabetes-related studies from 2000 to 2025, while identifying emerging hotspots such as nutrigenomics and metabolomics. A total of 700 scientific documents were retrieved from the Scopus database. Bibliometric indicators and science mapping techniques—utilizing VOSviewer and Biblioshiny (RStudio)—were employed to analyze keyword co-occurrence networks, thematic evolution, and research dynamics. The field demonstrated a 19.5% average annual growth rate, encompassing 265 journals and 4,089 authors, reflecting a highly collaborative global environment. Thematic evolution revealed a distinct shift from early foundational studies on antioxidant activity and enzyme inhibition toward current research emphasizing molecular docking, gene modulation, and metabolic profiling. Recently, nutrigenomics and metabolomics have emerged as prominent focus areas. This bibliometric analysis provides a quantitative overview of the research landscape surrounding kaempferol and diabetes. The findings highlight an ongoing transition toward integrative, omics-based strategies, offering a structured foundation to guide future mechanistic and translational investigations.
