Abstract

Curcuma xanthorrhiza Roxb. or Java Turmeric with the local name of Temulawak is one of herbal medicines used in Indonesia. This plant is believed to prevent some degenerative diseases due to its active compounds, especially curcumin (CUR) contained in Java Turmeric. Therefore, analysis of active components including CUR is very urgent. This study highlighted the development of FTIR spectroscopy coupled with PLSR for the determination of CUR in Java Turmeric powders. The levels of CUR in Java Turmeric powders were determined using HPLC with UV detectors, and the obtained results were used as actual values to be predicted using FTIR spectroscopy-multivariate calibrations. The results revealed that the levels of CUR ranged from 0.6741 ± 0.0705% (g/100 samples) to 2.1062 ± 0.0095%. PLSR modeling for the relationship between the actual value of CUR as determined using HPLC and calculated values as predicted using FTIR spectroscopy provide the value of R2 of 0.9990 with RMSEC of 0.0028. The developed method offers reliable results providing a green analytical method due to the use of minimum solvent and reagent and does not involve extensive sample preparation.

Abstract

Various test methods have been previously documented for determining vitamin A levels in different dosage forms. This study specifically examines an isocratic reverse phase-high performance liquid chromatography (RP-HPLC) method designed for the direct extraction of vitamin A. The objective is to validate an analytical method for quantifying vitamin A in bioadhesive cationic nanoemulsions incorporated into thermosensitive gels. The method employs isocratic RP-HPLC with a YMC-Triart C18 column (L1), dimensions of 4.6 mm × 250 nm, particle size of S-5 µm, and a UV detector at λ = 265 nm. The mobile phase consists of HPLC-grade methanol, acetonitrile, and n-hexane in a ratio of 46.5:46.5:7. Validation parameters were assessed including selectivity, linearity, accuracy, precision, limit of quantification (LOQ), and limit of detection (LOD). Correlation coefficients were determined with an R2 value of 0.9995 in the concentration range of 264–396 μg/mL (w/v). Recovery percentages ranged from 99.295% to 99.878%. Repeatability and intermediate precision relative standard deviations (RSD) were found to be 0.318% and 0.254%, respectively. The LOD was established at 2.018 μg/mL, and the LOQ was determined to be 6.114 μg/mL. The results affirm cost-effective and well-suited for the accurate measurement of vitamin A levels in bioadhesive thermosensitive gel formulations.

Abstract

Gaharu (Gyrinops versteegii (Gilg.) Domke) is a native Indonesian plant with many potential medicinal compounds. The compounds contained in the chloroform extract of gaharu leaves are mostly nonpolar terpenoids and fatty acids, so their solubility in water is low. Self-nanoemulsifying drugs delivery system (SNEDDS) technology can increase the solubility and bioavailability of drugs or active compounds in cells. This study aims to formulate and characterize SNEDDS from chloroform extract of gaharu leaves. The research began with the extraction of gaharu leaves by soxhletation. Formula optimization was carried out with various oils, surfactants, and cosurfactants. SNEDDS preparations were then characterized by testing particle size, polydispersity index, percent transmittance, and determining globule morphology. The optimal SNEDDS formula contained miglyol® 812N oil and Tween 80 (32%:68%) with particle size 63.25 ± 5.93 nm, polydispersity index 0.272 ± 0.016, and percent transmittance 98.33 ± 0.23%, spherical globule morphology. This study concluded that the optimal formula for SNEDDS chloroform extract of gaharu leaves (Gyrinops versteegii (Gilg.) Domke) had good physical characteristics.

Abstract

Losartan, an antihypertensive agent, has low oral bioavailability. Therefore, developing a design for transdermal delivery of losartan is interesting. This study aims to enhance losartan in vitro transport by incorporating it into chitosan nanoparticles. Transdermal transport studies were conducted using two experimental groups: the pretreatment group using oleic acid and propylene glycol, and the group without pretreatment. The results showed that losartan incorporated into chitosan nanoparticles resulted in a significantly higher amount of drug being transported than the losartan solution (control) in both experimental groups. In the experiment without pretreatment, the amount of losartan from the control could not be detected in the receptor compartment until 28 hours. In contrast, losartan was detected at 16 hours of transport from chitosan nanoparticles. In pretreatment, chitosan nanoparticles exhibited 6.6fold higher losartan transport than the control. In addition, losartan chitosan nanoparticles showed significant increases in steady-state flux and transport efficiency by 3.3 and 6.6 times higher than the control, respectively. It can be concluded that the incorporation of losartan into chitosan nanoparticles can increase its transdermal transport.

Abstract

Fish is a product with high nutritional content, and the development of fish oil has made it easier for consumers to consume. High-quality fish oil can be a target for adulteration, such as with vegetable oils like palm oil. FTIR spectroscopy was developed for the authentication of bawal fish oil (BFO) from palm oil (PO). Bawal fish oil and palm oil were prepared in binary mixtures with concentrations from 0-100%, resulting in 21 mixtures. The oil was directly measured by attenuated total reflectance (ATR) spectral measurement in the mid-infrared region (4000-600 cm-1). The results were combined with linear discriminant analysis (LDA) and multivariate calibration, such as PLSR or PCR. The results showed that LDA could make clear discrimination between bawal fish oil, palm oil, and their mixtures without any misclassification observed. Multivariate calibration with PLSR using the first derivative spectrum provided the best model for the relationship between actual and predicted FTIR values. At this conditions, the R2 values for the calibration and validation models obtained were 0.9966 and 0.9969, with RMSEC and RMSEP values of 0.0249 and 0.0248, respectively. Therefore, FTIR spectroscopy combined with LDA and PLSR is an effective method for authenticating bawal fish oil from palm oil.

Abstract

The ethanol extract of Plantago major L. leaves contains secondary metabolites, including phenolics and iridoid glycosides, which exhibit anti-inflammatory and wound-healing properties. Nanoparticle technology, in the form of nanosuspensions, is a method that can enhance the ability of active compounds to pass through cell membranes at the nanoscale. This study aimed to characterize and investigate the effects of varying chitosan concentrations on the nanosuspension formulation of Plantago major L. ethanol leaf extract using the ionic gelation method. The ethanol extract was formulated into nanosuspensions with five different concentrations of chitosan polymer: 0.25% (F1), 0.5% (F2), 0.75% (F3), 1% (F4), and 1.25% (F5). Testing parameters included particle size, polydispersity index (PDI), and zeta potential, measured using the Malvern Zetasizer Nano ZS instrument. The characterization results for all formulations showed an average particle size ranging from 445.7 to 811.5 nm, a PDI ranging from 0.385 to 0.518, and a zeta potential between 23.9 and 31.0 mV. These results indicate that all formulations fall within the nanoparticle size range (10–1,000 nm), exhibit relatively homogeneous polydispersity indices, and display stable zeta potentials. Variations in chitosan concentration in each nanosuspension formula of ethanol extract of Plantago major L. influenced the characterization, with increasing chitosan concentration resulting in larger particle sizes and higher zeta potentials, thereby enhancing the potential for these nanosuspensions to be formulated into drug delivery systems.
