Abstract

Oil palm leaves could yield various health benefits, potentially leading to innovative applications in natural remedies, supplements, and dietary products. Targeted extraction and sophisticated analytical methods have become necessary for investigating bioactive compounds in plant materials. The combination of liquid chromatography and high-resolution mass spectrometry (LC–HRMS) makes for a potent technique for analyzing a wide range of metabolites, allowing for the precise and sensitive identification of various plant compounds. This investigation aimed to examine the active compounds in the ethyl acetate fraction of Elaeis guineensis leaves using LC–HRMS to identify potential new avenues for drug research. The simplicia was extracted by completely immersing 500 g of granules in acetone for three days. The crude extract was fractionated with n-hexane, ethyl acetate, and n-butanol solvents to separate components according to their polarity. The ethyl acetate part was analyzed using LC–HRMS with specific settings, including a temperature of 30°C and a gas flow rate of 11.01 L/min. The extract yield from dense oil palm leaves was 32.5 g, equivalent to 6.5%. Subsequently, the components were separated by fractionating the complete yield. The n-hexane fraction yield was 7.085 g or 21.83%, the ethyl acetate fraction yield was 3.38 g or 10.4%, the n-butanol fraction yield was 8.84 g or 27.2%, and the remaining fraction yield was 3.93 g or 12.1%. In conclusion, oil palm leaves are a prospective source of zingerol compounds, suggesting potential to be used as an alternative to rhizomes.

Abstract

Cucumber peel (Cucumis sativus L.), often considered an agricultural waste, contains significant levels of flavonoids with antioxidant properties that can prevent premature skin aging. This study aimed to formulate and evaluate the physical properties of peel-off gel masks made from cucumber peel extract in three different concentrations: F1 (0.5%), F2 (1%), and F3 (1.5%). This study was conducted experimentally. The extracts were obtained through maceration using 96% ethanol and incorporated into the Peel-Off mask formulations. The physical quality of the mask formulations was assessed through organoleptic evaluation, homogeneity, spreadability, adhesion, pH, and drying time tests. The results showed that all formulations met the desired criteria. All three formulations showed consistent color, aroma, and viscosity for up to four weeks. The homogeneity test ensured uniform distribution of ingredients without visible lumps. Spreadability values ​​ranged from 5.2 to 5.3 cm, within the optimal range of 5–7 cm. The pH value of all formulations was 6, which is within the safe range for skin application. Adhesion tests showed increased adhesion time with higher extract concentrations, ranging from 15.3 to 17.3 seconds. Drying times for all formulas were within the acceptable range of 15–30 minutes. In conclusion, the peel-off gel masks formulated with cucumber peel extract exhibited suitable physical characteristics and potential for practical cosmetic use, with F3 offering slightly superior performance in some parameters.

Abstract

Yogurt is a fermented dairy product typically produced using lactic acid bacteria such as Lactobacillus bulgaricus and Streptococcus thermophilus. It is widely recognized for its health benefits, particularly in supporting gut microbiota balance. In recent years, incorporating natural ingredients into yogurt formulations has gained increasing attention, as consumers seek functional foods with added health value. One such ingredient is telang flower, which has been recognized for its richness in antioxidants and anthocyanins. Moreover, it contains polyphenolic compounds like catechins, which are associated with improved metabolic activity and increased fat oxidation, potentially supporting weight control. Ongoing innovations in yogurt development aim to enhance its flavor, texture, and stability, often by incorporating sweeteners and thickening agents. This study aimed to evaluate the sensory properties and consumer acceptability of telang flower yogurt formulated with varying concentrations of natural sweetener (honey) and thickening agent/stabilizer (carboxymethyl cellulose, CMC), and to characterize the physical and chemical attributes of the optimum formula. Four formulations were developed using different concentrations of honey (0%, 10%, 15%, and 20%) and CMC (0%, 1%, 1.5%, and 2%). Formulation FIV, consisting of 20% honey and 2% CMC, achieved the highest level of preference among all tested variants. A vibrant purple color, dense texture, pleasantly acidic aroma, and well-balanced sweetness contributed to its superior sensory profile. This formula exhibited favorable physicochemical characteristics, with a pH of 4.34 and a viscosity of 1910 cP. Increasing honey and CMC concentrations were found to improve both consumer acceptability and the overall sensory.

Abstract

Providing drug information is a crucial component in pharmaceutical services that aim to ensure the safe and rational use of medications. However, the practice of providing information by pharmacy technicians in pharmacies is often not optimal, especially in educational aspects related to patient safety. The purpose of this study was to evaluate the behavior of pharmacy technicians in providing drug information to patients at X Network Pharmacies in Pekanbaru City. This research is a quantitative descriptive study with a cross-sectional approach. A total of 32 pharmaceutical technicians became respondents, selected through a total sampling method. Data were collected using a structured observation sheet that included 15 indicators of drug information provision. Data were analyzed descriptively and presented in the form of a frequency distribution and a percentage. The results showed that the behavior of providing drug information by pharmaceutical technicians was still relatively low. Most of them only provided basic information, such as the name of the drug (78.12%), the time of consumption (71.87%), and instructions on how to use the drug (65.62%). Meanwhile, important information such as side effects, drug interactions, storage methods, and compliance with the use of drugs is almost not conveyed at all (≤10%). The behavior of pharmaceutical technicians in providing drug information still falls short of ideal pharmaceutical service standards. Continuous training, strict adherence to Standard Operating Procedures (SOPs), and supervision by the pharmacist-in-charge are necessary to enhance service quality and patient protection.

Abstract

Preserving dental and oral hygiene is essential to maintain the overall function of the oral cavity. Essential oil extracted from Pontianak orange peel shows potential as a safe and effective component for oral healthcare when incorporated into a mouthwash formulation. This research was conducted to evaluate the potential of Pontianak orange peel essential oil as an antibacterial mouthwash effective against Streptococcus mutans. The study was conducted by formulating mouthwash preparations using different concentrations of Pontianak orange peel essential oil: 3%, 4%, and 5%, followed by evaluation of physical properties including organoleptic characteristics, homogenity, pH level, sedimentation, specific gravity, and viscosity. The antibacterial properties were tested using  the disc diffusion method.The physical evaluation results showed that the mouthwash had a sweet taste, green color, a citrus peel aroma with a hint of mint; it was homogeneous, with no sedimentation; had a pH value ranging from 5.13 ± 0.02 to 5.25 ± 0.02; specific gravity ranging from 0.9968 ± 0.06 to 1.0424 ± 0.00 g/ml; and viscosity ranging from 1.717 ± 0.02 to 1.920 ± 0.01mPa.s. All formulations met the physical property requirements of a good mouthwash to ensure comfort during use. The largest inhibition zone was observed at the highest essential oil concentration (5%), with a diameter of 8.04 ± 1.05 mm, which falls under the category of moderate antibacterial activity. This study indicates that a mouthwash containing 5% Pontianak orange peel essential oil is effective in inhibiting the growth of Streptococcus mutans.
