Abstract

Background: Chitosan is a biopolymer derived from the deacetylation of chitin, which is generally obtained from crustacean waste. However, the utilization of more environmentally friendly alternative sources such as oyster mushrooms (Pleurotus ostreatus) has recently been developed. Chitosan exhibits biocompatible, biodegradable properties and antibacterial activity, making it potentially applicable in the food and pharmaceutical industries. Objective: This study aims to extract and characterize chitosan from oyster mushrooms and to evaluate its antibacterial activity against Escherichia coli. Methods: The study was conducted through extraction stages including deproteinization, depigmentation, demineralization, and deacetylation. Chitosan characterization included functional group analysis using FTIR, as well as physicochemical parameter testing such as yield, moisture content, ash content, and solubility. Antibacterial activity was tested using the disc diffusion method at various chitosan concentrations (0.3%, 0.5%, 0.7%, and 0.9%). Results: The obtained chitosan had a degree of deacetylation of 80.64%, indicating successful conversion of chitin into chitosan. The physicochemical characteristics met quality standards, with a yield of 52.84%, moisture content of 0.666%, and ash content of 0.416%. Chitosan was soluble in 2% acetic acid. Antibacterial testing demonstrated inhibitory activity against Escherichia coli, with inhibition zones ranging from 10.1 to 14.2 mm, categorized as strong. Conclusion: Chitosan extracted from oyster mushrooms exhibits good physicochemical characteristics and promising antibacterial activity, indicating its potential as an environmentally friendly alternative material for applications in the food and pharmaceutical fields.

Abstract

The bajakah plant is one of the biological plants used in traditional medicine. Bajakah is also a medicinal herbal plant that can be used in all its parts. This plant can be found in the depths of Kalimantan Province, but it has not spread to other regions. There has been no effort to cultivate bajakah because of the lack of understanding of the local population about the use of this plant. This research includes the stages of processing plant materials, making ethanol extracts, characterization examinations, phytochemical screening, and determining total flavonoid levels of ethanol extract of Bajakah wood using the visible spectrophotometry method and antibacterial activity. Bajakah wood extract was made by maceration method using ethanol concentrations of 96%, 70%, and 50%, and the extract obtained was concentrated with a rotary evaporator, then the total flavonoid level was determined using the visible spectrophotometry method and antibacterial activity tests were carried out against Staphylococcus aureus As a positive control using chloramphenicol and negative control using dimethyl sulfoxide. The results were obtained by determining the maximum wavelength of quercetin and operating time, measuring the quercetin calibration curve, and calculating the total flavonoid level using the visible spectrophotometry method. The results obtained in the determination of total flavonoid levels in Bajakah wood ethanol extract at a concentration of 96% were 349.888 ± 4.5022 mg QE/g, at a 70% concentration of 307.137 ± 6.7626 mg QE/g and a 50% concentration of 6.15173 ± 2.9148 mg QE/g.

Abstract

Jamur susu harimau (Lignosus rhinocerus) merupakan tumbuhan langka yang telah lama digunakan secara tradisional dan memiliki potensi besar sebagai agen antibakteri dan antioksidan, terutama di tengah meningkatnya masalah resistensi antibiotik. Hal ini didukung oleh kandungan senyawa metabolit sekunder seperti flavonoid, steroid, tannin, alkaloid, dan saponin yang berperan penting dalam melawan infeksi bakteri patogen dan menetralkan radikal bebas penyebab kerusakan sel. Penelitian eksperimental ini bertujuan untuk menganalisis secara kuantitatif aktivitas antibakteri dari ekstrak etanol jamur susu harimau terhadap bakteri Gram-positif Staphylococcus aureus dan Gram-negatif Escherichia coli, serta mengevaluasi kapasitas antioksidannya menggunakan dua metode komplementer, yaitu DPPH dan FRAP. Ekstraksi dilakukan dengan metode maserasi menggunakan pelarut etanol 96% dari serbuk simplisia, dan pengujian aktivitas dilakukan pada tiga variasi konsentrasi: 50%, 60%, dan 70%. Hasil uji antibakteri menunjukkan aktivitas yang kuat dan bersifat konsentrasi-tergantung. Pada konsentrasi 70%, diameter zona hambat mencapai 20,40 mm untuk S. aureus dan 16,30 mm untuk E. coli. Pada uji antioksidan, ekstrak menunjukkan kemampuan yang signifikan dengan nilai IC50 sebesar 86,15 ppm (metode DPPH) dan 77,13 ppm (metode FRAP), yang termasuk dalam kategori kuat. Secara keseluruhan, hasil ini tidak hanya mengonfirmasi potensi jamur susu harimau sebagai sumber senyawa bioaktif alami, tetapi juga memberikan dasar ilmiah yang kuat untuk pengembangannya lebih lanjut sebagai agen terapeutik baru dalam mengatasi infeksi bakteri dan mitigasi stres oksidatif.

Abstract

Porang (Amorphallus muelleri Blume) is one type of tuber plant that has the potential to be developed in Indonesia. Porang plants have been reported to contain chemical compounds that have antioxidant activity. This research was conducted on the leaves of the porang plant with the aim of knowing the antioxidant activity, characterization, and phytochemical profile of the compounds contained therein. Compound identification and characterization were performed using standard methods, and antioxidant activity was determined using the DPPH (1,1- Diphenyl-2-picrylhydrazyl ) method. The results of the identification of chemical compounds showed that the ethanol extract of porang leaves contained chemical compounds of alkaloids, flavonoids, tannins, saponins, and steroids. The results of the examination of the simplicia characterization of porang leaves included the soluble ethanol content of 33.93%, the water soluble extract content of 17.3%, the ash content of 5.58%, the acid insoluble ash content of 0.235% and the water content of 8%. From the results of the simplicia characterization, it shows that the results meet the specified requirements. The results showed that the ethanol extract of porang leaves had antioxidant activity with an IC50 value of 93.04 µg/mL, which in this case is included in the category of strong antioxidant activity. Meanwhile, as a comparison, Vitamin C was used, which has an IC50 value of µg/mL, which is included in the category of very strong antioxidant activity.

Abstract

Introduction: Cocoa beans (Theobroma cacao L.) are widely recognized as a rich source of bioactive polyphenolic compounds, particularly flavan-3-ols such as catechin and epicatechin, which exhibit potent antioxidant properties. These secondary metabolites play a critical role in neutralizing free radicals, thereby mitigating oxidative stress implicated in various degenerative diseases. Objective: This study aimed to compare catechin equivalent content and DPPH radical scavenging activity between ethanolic extract (maceration with 70% ethanol) and aqueous infusion (90°C, 15 min) of cocoa beans. Methods: Phytochemical screening was conducted qualitatively. Catechin equivalent content was determined using UV-Vis spectrophotometry at 280 nm, while antioxidant activity was evaluated using the DPPH method at 515 nm with vitamin C as positive control. Results: Both samples contained alkaloids, flavonoids, saponins, tannins, triterpenoids/steroids, polyphenols, and glycosides. The ethanolic extract exhibited higher catechin equivalent content (37.15 ± 0.07 µg/mL) compared to the infusion (19.83 ± 0.10 µg/mL), corresponding to 12.53 ± 0.72 mg/g and 11.18 ± 1.72 mg/g, respectively. The DPPH assay revealed superior antioxidant activity for the ethanolic extract (IC₅₀ = 83.29 µg/mL; strong category) compared to the infusion (IC₅₀ = 192.65 µg/mL; weak category), with vitamin C showing IC₅₀ = 2.95 µg/mL (very strong). Conclusion: Ethanolic maceration is more effective than aqueous infusion for extracting catechin equivalents and achieving higher antioxidant activity from cocoa beans. Further confirmation using HPLC-DAD or LC-MS is recommended to validate specific catechin concentrations.
