This research is intended to evaluate sub-chronic toxicity of standardized combination extract of meniran and pegagan on liver and kidney function. This research used post-test-control design. Twenty female and twenty male Wistar strain rats divided into 4 groups. The first group was controlled in dosage of CMC Na 0.5%. The others were given a combination of meniran and pegagan extract in ratio with different dosage (50:50; 250:250; and 1250:1250 mg/KgBW). Sub-chronic toxicity test of meniran and pegagan combination was given orally once a day for 28 consecutive days. On the 29th day, all the rats were sacrificed and blood samples were analyzed using automatic analyzer. SGOT, SGPT, BUN, and creatinine value were statistically analyzed using one way ANOVA with post hoc LSD (p0.05). The results show that treatment of meniran and gotu kola combination had no significantly different of SGOT and creatinine value of male and female rats, and SGPT value of male rats (p0.05). The treatment of meniran and gotu kola combination had significantly different of BUN value of male and female rats, and SGPT value of female rats (p0.05) but still within normal range. Based on this study, it can be concluded that orally administered of meniran and gotu kola extract combination at doses 50:50 mg/KgBW; 250:250 mg/KgBW; and 1250:1250 mg/KgBW had no affected on SGOT, SGPT, BUN and creatinine value of Wistar strain rats on sub-chronic administration for 28 consecutive days.

Abstract

Analytical Validation Method to determine β-carotene in the Spirulina platensis extract chewable tablets need to be done to ensure the quality. The purpose of this study is to prove the validity of the TLC-Densitometry method for determining the levels of β-carotene in the Spirulina platensis extract chewable tablets. Validation of the analysis method was carried out using standard β-carotene and spirulina chewable tablets in ethyl acetate solvents including specificity, linearity, repeatability precision, intermediate precision, limit of detection and limit of quantitation with stationary phase of silica gel 60 F254 and mobile phase of acetone: ethyl acetate (1: 1 v/v) using the TLC method, then quantitative analysis was carried out with a Densitometer at a wavelength of 453 nm. The results showed that the TLC-Densitometry method was linear with an r value of = 0.9938, having a repeatability precision with RSD 1.89%, intermediate precision with an RSD value of 2.401%, an LOD of 0.159 mg/mL and an LOQ of 0.531 mg/mL, and the specificity showed that this method is not specific to β-carotene compounds and the accuracy does not indicate a recovery value. Based on these results it can be concluded that the TLC-densitometry method is invalid for the determination of β-carotene levels in the Spirulina platensis extract chewable tablets.

Abstract

Background: Meniran (Phyllathus niruri) and pegagan (Centella asiatica) are well-known medicinal plants in Indonesia. Uses of meniran and pegagan as herbal medicines need to be examined for their subchronic activity to assure their safety. Objective: This study aimed to evaluate subchronic effects of a combination of extracted meniran and pegagan on Wistar rats through haematological parameters (erythrocytes, haemoglobin, haematocrit, MCV, MCH, and MCHC).Methods: Animal models used were 56 male and female Wistar rats and were divided randomly into 4 groups. Group 1 received CMC-Na 1% (control group). Group 2 received extracts of meniran and pegagan (50:50 mg/kgBW). Group 3 received extracts of meniran and pegagan (250:250 mg/kgBW). Group 4 received extracts of meniran and pegagan (1250:1250 mg/kgBW). Subchronic test of meniran and pegagan was conducted by providing treatments for the Wistar rats for 28 days. Their haematological substances were analysed statistically by using one way ANOVA and Kruskal-Wallis method with confidence interval of 95% and post-hoc. Results: This study found that the haematological substances in male Wistar rats were normal and did not significantly change (p>0,05). It also showed that haemoglobin and haematocrit substances in female rats were normal and did not significantly change (p>0,05). Erythrocytes, MCV, MCH, and MCHC in female rats indicated significant change (p<0,05), but they were still in normal ranges.Conclusion: It could be concluded that administration of the combination of extracted meniran and pegagan was not toxic to haematology of the rats in all doses.

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

Trichophyton rubrum is a common fungus that causes a dermatophyte infection known as tinea cruris. More than a fifth of the population in Indonesia suffers from this infection.  Alpinia purpurata K. Schum or well known as red galangal is said to have antifungal properties because of its composition, which includes compounds such as volatile oil, acetyl chavicol, flavonoids, and phenols. This study was aimed to determine the antifungal activity of a oil-in-water-based cream containing red galangal rhizome extract (RGRE) against T. rubrum. RGRE was obtained by macerating the rhizomes in a solvent of 96% ethanol and evaporating until a thick extract was obtained. The extract was then formulated into an oil/water-based cream at concentrations of 10%, 15%, and 20%. The creams were evaluated for their physical properties, including organoleptic properties, homogeneity, pH, viscosity, adhesivity, and spreadability. The antifungal activity was tested using the agar diffusion method against T. rubrum. Data on the physical properties of the creams and their antifungal activity were analyzed using a one-way ANOVA test with a 95% confidence level. The results showed that creams with higher RGRE concentrations exhibited decreased spreadability and pH values but increased the viscosity and adhesivity test. The antifungal activity increased with higher RGE concentrations, starting at 10%, 15%, and 20%, with inhibition diameters of 12.33 mm, 18.83 mm, and 21.66 mm, respectively. Statistical analysis showed that RGE concentration affected the physical properties of the cream, including pH, spreadability, viscosity, adhesivity test as well as antifungal activity (p < 0.05). In conclusion, the water-in-oil-based cream containing 20% RGRE exhibits favorable physical properties and antifungal activity.
