Abstract

Sida rhombifolia belongs to the Malvaceae family and is often used to treat gout in Indonesia. S. rhombifolia has many efficacies and contains many different chemical components. The abundance and variation of chemical content and chemical compounds in this medicinal plant are challenging factors in ensuring medicinal plants' safety and quality control. Thin-layer chromatography (TLC) fingerprint analysis derived from S. rhombifolia extract can also be used for the medicinal plant's quality control. This research aimed to develop the optimum condition for the chemical fingerprint analysis of S. rhombifolia using a TLC fingerprint analysis. A total of 11 bands were produced with optimum separation using silica gel 60 F254 TLC plate, a mixed mobile phase condition with chloroform, ethyl acetate, and methanol (6.5:2:1.5). This fingerprint analysis performed an excellent separation in the TLC plate at 366 nm with sulfuric acid as reagent derivatization. In general, the results of the analysis validation, including stability, specificity, precision, and robustness of TLC fingerprints, met the acceptance criteria. The TLC fingerprint of S. rhombifolia can be distinguished from 2 related plants with similar leaf shapes, Turnera ulmifolia L. and Hibiscus rosa-sinensis. The developed method was validated, so it could be used to control S. rhombifolia quality.

Abstract

Sida rhombifolia, also known as sidaguri in Indonesia, is a medicinal plant commonly used as a herbal medicine because of its metabolite and biological activities. One of the several factors that affect plant metabolite composition and concentration is the use of plant parts. In this study, the experiment aimed to identify the metabolite profile in the leaves and stem extracts of S. rhombifolia using UHPLC-Q-Orbitrap HRMS-based untargeted metabolomics. The samples were distinguished by principal component analysis (PCA). Extraction of metabolites was conducted by sonication for approximately 30 min with 70% ethanol as the extraction solvent; 28 metabolites were identified. Seven metabolites were identified only in the leaves, three were identified only in the stems, and 18 other metabolites were identified in both the leaves and stems. These metabolites were categorized as flavonoids, triterpenoids, alkaloids, coumarins, phenolic aldehydes, phenolic acids, ecdysteroids, fatty acids, and monoterpene lactones. Based on the classification results, PCA grouped the leaves and stem extracts of S. rhombifolia using the peak area variables of the identified metabolites.

Abstract

Black turmeric (Curcuma aeruginosa) is Indonesian medicinal plant belonging to the Zingeberaceae family, mostly found on Java. This study aimed to determine the new molecular structures of the compounds isolated from black turmeric originating from Indonesia. Isolation of the secondary metabolite compounds was initiated by solid-liquid extraction using the maceration method with ethanol solvent, followed by liquid-liquid extraction using the partition method with n-hexane and dichloromethane as solvents. Separation and purification were carried out using vacuum liquid chromatography (VLC) and gravity column chromatography (GCC). The isolated compounds were characterized using spectroscopic methods, including UV-Vis, IR, and NMR spectroscopy. The isolation resulted in three sesquiterpenoid compounds, (E)-7-isopropyl-4,10-dimethylcyclodec-10-ene-5,8-dione (curdione), (1R,10R)-Epoxy-(-)-1,10-dihydrocurdione, and zedoalactone B, together with two common terpenes, ethyl tetradecanoate and 1-hexadecene.

Abstract

Structure-based was performed to understand the mechanism inhibition of pyrimethamine (CP6) against Plasmodium Falciparum mutants at the molecular level. A molecular docking process was carried out to obtain the initial conformation of each system. The data showed in the form of RMSD values, hydrogen bonds, and grid scores. The results show that the RMSD value in the redocking process meets the criteria of the CP6-1J3J and WRA-1J3K complexes with a value of ≤ 2 í…. Several hydrogen bonds bind to receptor-active sites, including Ile14, Asp50, Ile164, and Asn108. Additionally, the grid score (kcal/mol) binds well on the active site: CP6-1J3J (-46.86), WRA-1J3K (-65.40), and CP6-1J3k (-44.71). Furthermore, molecular dynamics simulation was carried out to determine the free energy (∆Gbind) of each complex using the MM/GBSA approach. The results show ∆Gbind (kcal/mol) in each complex, namely CP6-1J3J (-28.24), WRA-1J3K (-36.62), and CP6-1J3k (-24.23). Information on this research was expected to provide molecular insight into pyrimethamine as an antimalaria inhibitor.

Abstract

The International Community Services program (ICS) at Universitas Airlangga, part of the Tri Dharma of the university focusing on community service, aims to enhance human resource capacities within communities. In 2024, the program targeted Senden Village, Kampak sub-District, Trenggalek District, East Java, Indonesia, to assist its MSMEs in overcoming packaging challenges that hinder market interest. Collaborating with domestic and international universities, including Universitas Mayjen Sungkono, SMBBMU University Larkana Pakistan, UiTM Negeri Sembilan Malaysia, UM Malaysia, and Meijo University Japan, the program provided intensive training on innovative and functional packaging techniques. This program was chosen and considered urgent because processed food products produced by local MSMEs are still sold in bulk and packaged haphazardly. Therefore, a touch of hygienic and "eye-catching" packaging technology is needed. Attractive and hygienic packaging technology is expected to increase the selling power of these processed food products. The training included theoretical sessions, focus group discussion (FGD) demonstrations, and the introduction of plastic vacuum sealers to improve product packaging and branding. Food packaging workshop held on July 15, 2024, where participants engaged in hands-on training, group discussions, and label design, resulting in tangible improvements in product marketability. The initiative of this activity is not only to increase the visibility and attractiveness of Senden Village products but also to introduce the natural exotism of the village and local products to the national and international community, encouraging cultural and knowledge exchange. The collaboration of this program strengthens international collaboration and provides invaluable experience for students and lecturers. The successful implementation of this program confirms Airlangga University's commitment to community service and its goal of creating a sustainable positive impact on the village community, which ultimately contributes to the development of better human resources. The training has been carried out very well and each training participant has their own brand with an attractive logo and is hygienically packaged with vacuum technology. All training participants were satisfied with this activity as well as head of village, head of PKK, and all the team involved. They hope that next year's activities can be carried out with other innovations for the progress of Senden village.
