Abstract

Porang tuber (Amorphophallus muelleri Blume) is a potential natural resource that can be developed as an active ingredient in cosmetic preparations, particularly liquid soap. This study aimed to formulate and evaluate liquid soap containing porang tuber extract and to determine its physical quality characteristics. The tubers were extracted by maceration using 70% ethanol. Prior to extraction, simplicia characterization was performed, including determination of moisture content, water-soluble extractive, ethanol-soluble extractive, total ash, and acid-insoluble ash. Phytochemical screening was carried out to identify secondary metabolites. The extract was formulated into liquid soap preparations with concentrations of 3%, 5%, and 8%. The evaluation included organoleptic tests, pH measurement, foam height test, irritation test, and hedonic test. The results of simplicia characterization showed that all parameters met the requirements of the Herbal Pharmacopeia. Phytochemical screening indicated the presence of alkaloids, flavonoids, saponins, tannins, and triterpenoids. The formulated liquid soaps showed acceptable physical characteristics, pH values within the Indonesian National Standard range (8–11), adequate foam formation, and no skin irritation. Hedonic testing demonstrated that all formulations were acceptable to panelists. It can be concluded that porang tuber extract has potential as a natural active ingredient in liquid soap formulations.

Abstract

Andaliman (Zanthoxylum acanthopodium DC.) is an endemic spice from North Sumatra with significant therapeutic potential derived from its essential oils. Terpenoid compounds such as geranyl acetate, limonene, and citronellol in andaliman are recognized for their efficacy in aromatherapy to alleviate nausea and vomiting. This study aims to construct an aromatherapy roll-on formulation using andaliman fruit essential oil and to evaluate its physical characteristics and safety profile. The research employed a laboratory experimental method, utilizing the Stahl steam distillation technique for essential oil isolation. The preparations were formulated into three concentration variations: F0 (0%), F1 (5%), and F2 (10%). Evaluation parameters included organoleptic properties, homogeneity, viscosity, pH value, dermal irritation tests, and hedonic (preference) tests. The results demonstrated that all formulas maintained excellent physical stability and homogeneity. The pH values ranged from 5.52 to 6.06, which is considered safe as it aligns with the physiological pH of human skin (4.5–6.5). Irritation tests confirmed that the formulations did not trigger adverse skin reactions in respondents. According to the hedonic test, panelists showed high preference for aroma, texture, and comfort, although the scent longevity requires further optimization due to the volatile nature of the essential oil. Overall, the andaliman essential oil aromatherapy roll-on meets the physical quality and safety standards for topical preparations.

Abstract

Porang tuber (Amorphophallus muelleri) contains various bioactive compounds with potential antioxidant activity, while extraction efficiency is strongly influenced by the applied method. This study aimed to compare conventional and environmentally friendly extraction techniques, including maceration, Soxhlet extraction, Microwave-Assisted Extraction (MAE), and Ultrasonic-Assisted Extraction (UAE), using 70% ethanol as the solvent. Antioxidant activity was evaluated using the DPPH radical scavenging assay and expressed as IC₅₀ values. The results showed that differences in extraction methods significantly affected antioxidant activity. Soxhlet extraction exhibited the highest antioxidant activity with the lowest IC₅₀ value (0.1788 µg/mL), followed by MAE (0.4312 µg/mL), maceration (0.6315 µg/mL), and UAE (0.6574 µg/mL). The superiority of the Soxhlet method is related to continuous solvent reflux and heat-assisted mass transfer, which enhance the release of antioxidant compounds. These findings confirm that porang tuber is a promising natural antioxidant source, with Soxhlet extraction identified as the most effective method under the applied experimental conditions for future development of functional food, nutraceutical, and pharmaceutical applications.

Abstract

Andaliman leaves (Zanthoxylum acanthopodium DC.) are a traditional plant native to North Sumatra with potential as a natural antioxidant source due to their phenolic and flavonoid compounds. This study aimed to evaluate the antioxidant potential of the ethyl acetate extract of andaliman leaves based on total phenolic content, total flavonoid content, and antioxidant activity. Extraction was carried out using the maceration method with ethyl acetate as the solvent. Total flavonoid content was determined using the AlCl₃ method with quercetin as the standard, while total phenolic content was analyzed using the Folin– Ciocalteu method with gallic acid as the standard. Antioxidant activity was evaluated using the DPPH radical scavenging assay. The results showed that the ethyl acetate extract of andaliman leaves contained 73.40 mg QE/g extract of total flavonoids (7.3%) and 148.48 mg GAE/g extract of total phenolics. The antioxidant activity test yielded an IC₅₀ value of 4,2485 µg/mL, indicating that the extract exhibits very strong antioxidant activity. The high levels of phenolic and flavonoid compounds are believed to play an important role in the radical scavenging activity observed. Based on these findings, it can be concluded that the ethyl acetate extract of andaliman leaves has strong potential to be developed as a natural antioxidant source for applications in the pharmaceutical and health fields.
