Aims This study aims to obtain the best formula and ensure that the assay analysis method used can provide accurate and reliable results so that they can be trusted. Methods: Parang romang leaf extract was added to the optimum mixture of tween 20/80, propylene glycol, and olive oil and then characterized including% transmittance, drug loading, emulsification time, particle size, index polydispersity, zeta potential, dissolution test, Scanning electron microscopy (SEM ) and validation of the analysis method including linearity, precision, accuracy, LOD, and LOQ. Result: The results showed the ratio of surfactant, co-surfactant, and olive oil which produced the optimum formula for SNEDDS, namely 26 ml; 17.5 ml; and 6.5 ml,% transmittance 85.90, drug loading 45.36, emulsification time for AGF, AIF, and aqua dest was 15-16 seconds, particle size 404.1 nm, index polydispersity 0.840, zeta potential -31.4 mV, dissolution test 92.13%, SEM in the form of spherical chunks, and the result of the validation test of the analytical method with a linearity of r = 0.9902, precision 0.436%, accuracy 103.738%, LOD 1.87 µ / ml and LOQ 5.57 µ / ml. SNEDDS parang romang leaf extract using olive oil as the oil phase, Tween 80 as a surfactant, and propylene glycol as a cosurfactant provide optimal nanoemulsion characteristics and validation of the analytical method meets the requirements. Conclusion: Formula 1 SNEDDS parang romang leaf extract using olive oil as the oil phase, Tween 80 as a surfactant, and propylene glycol as a cosurfactant is an optimal formula that provides good nanoemulsion characteristics and validation of analytical methods meets the requirements

Abstract

Morinda citrifolia. L leaf is a plant that has the potential as an antioxidant due to the presence of compounds in the form of flavonoids and other phenolic compounds that can function as natural antioxidants. In connection with this, research was carried out to Morinda citrifolia. L formulate leaf extract in the form of effervescent granules. Morinda citrifolia leaf extract was macerated with ethanol 96% as solvent. Phytochemical screening showsthat the extract contains flavonoids, tannins, saponins and alkaloids. The extract was formulated with various concentrations of F1 (20%), F2 (25%), F3 (4%). Determination of antioxidant activity using the DPPH free radical immersion method. The results showed that the concentration in the granules influenced antioxidant activity with IC50 values of 109.05 ppm, 101.33 ppm and 73.28 ppm, respectively

Abstract

Red Dragon Fruit Peel (Hylocereus polyrhizus W.) contains chemicals such as alkaloids, flavonoids, saponins, phenols, and steroids. Flavonoids and phenols are compounds that have antioxidant properties. Red Dragon Fruit Peel extract is formulated in effervescent granule dosage form with different concentrations of 0%, 20%, 25%, and 30% based on its antioxidant activity. The purpose of this study was to determine the effect of concentration differences on the antioxidant activity of effervescent granules produced. The research method uses a completely randomized design (CRD) which includes sampling, sample processing, phytochemical testing, extract preparation, effervescent granule preparation, effervescent granule physical quality testing, effervescent granule testing, antioxidant activity testing, and data analysis. Data from physical quality testing and the IC50 value of effervescent granules were analyzed descriptively using the Analysis of Variance (ANOVA) method with a 95% confidence level. The results obtained show that Red Dragon Fruit Peel extract can be formulated into effervescent granules, and the physical quality test results meet the physical quality requirements for all concentrations. The effervescent granule formulations produced at all concentrations have a very strong antioxidant effect (<50 ppm). The variation of Red Dragon Fruit Peel extract concentration in effervescent granule formulation has a significant effect on its antioxidant activity

Abstract

Diabetic nephropathy is one of the microvascular complications of diabetes mellitus (DM). One of the clinical signs of diabetic nephropathy is an increase in urea and creatinine levels. The use of medicinal plants containing antioxidants is one of the therapeutic strategies to prevent complications of DM. The noni plant (Morinda citrifolia L), especially the leaves, contains active substances that have the potential as antioxidants to be used as supportive therapy for DM. This study aims to identify the content of active substances in noni leaf extract and determine the potential of noni leaf extract to reduce creatinine, and urea levels in diabetic nephropathy rats. Noni leaf extract was obtained by maceration using 96% ethanol, and animal models of diabetic nephropathy were obtained by induction of streptozotocin 40 mg/kg BW. The test animals were divided into six groups, namely normal control, negative control, positive control, treatment 1, 2, and 3, each given extract doses of 250, 500, and 750 mg/kg BW. The results indicated the presence of flavonoids, alkaloids, steroids, saponins, and tannins in the noni leaf extract. Giving noni leaf extract can reduce, urea and creatinine levels significantly compared to negative controls. In conclusion, noni leaf extract can potentially prevent complications of diabetic nephropathy with an effective dose of 250 mg/kg BW.

Abstract

Prostate cancer is characterized by abnormal growth of prostate gland cells due to uncontrolled cellular proliferation. Brazilin, a homoisoflavonoid compound derived from Caesalpinia sappan L., is known for its anticancer activity. This study aimed to evaluate the cytotoxic effect of brazilin on DU145 prostate cancer cells through an in vitro assay employing the WST-8 method. The results showed that both brazilin and cisplatin significantly reduced the cancer cell survival rate compared to the negative control group (p < 0.05). Although no significant difference was observed between the two compounds at the highest concentration (ns), their IC₅₀ values differed significantly (p < 0.05), recorded at 18.92 ppm for brazilin and 0.03569 ppm for cisplatin; both were classified as highly active. These findings suggest that brazilin possesses cytotoxic potential comparable to cisplatin at elevated concentrations and may be developed further as a naturally derived anticancer agent.
