Abstract. Mefenamic Acid is one type of nonsteroidal antiinflammatory drug that works to relieve pain by blocking an enzyme that produces prostaglandins. The quality requirements that must be met by pharmaceutical preparations are levels contained must meet the level requirement as listed in the Indonesian Pharmacopoeia or other standard books. The purpose of this study was to conduct a validation test of ultraviolet spectrophotometry methods for determination of the Mefenamic Acid level in the suspension preparation. The sample consisted of three suspensions preparation under the trade name obtained from a pharmacy in the Medan city. The solvent used is sodium hydroxide (NaOH) 0,1 N solution and the measurement was done at a wavelength of 286 nm. Validation parameters determined were Accuracy, Precision, Linearity, Range, Limit of Detection and Limit of Quantitation. The results of the determination of the Mefenamic Acid suspension preparation under the trade name Pondex® was 100,39±0,21%, trade name Omestan® was 99,98±0,33% and trade name Novastan® was 103,21±0,83%. All the suspension preparations were determined meet the general level requirement, that contain not less than 90,0% and not more than 110,0% of the amount stated on the label. The results meet the requirements of the validation test of analysis methods with the parameter percent recovery 100,08% for accuracy, relative standard deviation 0,04% for precision, the correlation coefficient 1,0000 for linearity, range 8 μg/mL to 12 μg/mL, limit of detection limit 0,0118 μg/mL, limit of quantitation 0,0356 μg/mL.

Metamizole is a nonsteroidal antiinflammatory drug (NSAID) that functions as an analgesic, antipyretic, and antiinflammatory. Examination of active substance contents is a requirement that must be met to ensure the quality of drug preparations. The aims of this study were to develop and validate the Fourier Transform Infrared spectrophotometric method for the quantitation of metamizole content in marketed tablet preparation. Identification and determination of metamizole contents by Fourier Transform Infrared spectrophotometric method used methanol solvent in the wavenumber range 4000 cm–1 to 650 cm–1. The results showed that the specific wavenumbers of metamizole were 1649.3 cm–1; 1623.3 cm–1; and 1589.7 cm–1; and the contents metamizole in marketed tablet preparation ranged from (97.954 ± 0.121)% to (104.541 ± 0.257)%. From the validation method, the recovery result is 100.129%; the relative standard deviation is 0.057%; the limit of detection is 2.09526 mg/mL; the limit of quantitation is 6.34928 mg/mL; and the range 40 mg/mL to 60 mg/mL. The quantitation of metamizole contents can be carried out by Fourier Transform Infrared spectrophotometric method with accurate and precise quantitation results.

Abstract. Vitamin C (ascorbic acid) is micronutrient that is water soluble and indispensable for the body's metabolism, also plays a role in immune function. Vitamin C are easy to be absorbed actively. One of the fruits that contain vitamin C is melon fruit. Many varieties of melon fruit affect the vitamin C levels. The levels of vitamin C can be determined by 2,6-dichloroindophenol titration method using 2,6-dichloroindophenol solution. The advantages of the 2,6-dichloroindophenol titration method in the determination of vitamin C levels is reductor substances other than vitamin C are not oxidized by 2,6-dichloroindophenol. The examination begins with the determination of equivalence of 2,6-dichloroindophenol solution to vitamin C and followed by determination of vitamin C levels in several varieties of melon fruit. Equivalence of 2,6-dichloroindophenol solution to vitamin C was obtained 0,1347 mg vitamin C per 1 mL 2,6-dichloroindophenol solution. Levels of vitamin C in various varieties of melon fruit obtained that the highest levels was in Golden Melon variety (9,209 mg vitamin C per 100 g of Golden Melon) while the lowest levels was in Langkawi Melon variety (0,335 mg of vitamin C per 100 g of Langkawi Melon). It can be concluded that vitamin C levels contained in melon fruit vary and depend on melon fruit varieties.Keywords: Vitamin C, Ascorbic Acid, Melon Fruits, Varieties, Titration MethodREFERENCE S.

Vitamin C, as a crucial nutrient, plays a vital role in human health and is known to be sensitive to various factors such as ripeness level, storage and heating conditions. This study aimed to determine the effect of ripeness level, storage and heating conditions on vitamin C in fig (Ficus carica L.) fruit juice using bivolmetric sensor. Fig (Ficus carica L.) fruit juice samples with different ripeness level were collected and analyzed the vitamin C. Full-ripe fig (Ficus carica L.) fruit juice samples subjected at different storage (cold, cool, and room temperature) and heating (30 °C, 60 °C, and 90 °C) conditions. The vitamin C level was monitored using a bivoltammetry sensor. The results showed that the higher ripeness level of fig (Ficus carica L.) fruit the lower level of the vitamin C. The results also showed that the higher storage and heating conditions generally accelerate with degradation of vitamin C. Degradation of vitamin C content in fig (Ficus carica L.) fruit juice with all different storage temperature had the best kinetic model fit zero order. Meanwhile, heating temperature at 30 °C and 60 °C showed that the best kinetic model fit first order. But, heating temperature at 90 °C showed that the best kinetic model fit second order. The kinetic modeling analysis showed that storage and heating conditions significantly influenced the degradation kinetics of vitamin C in the fig (Ficus carica L.) fruit juice.

From the validation method, the recovery result is 100.129%; the relative standard deviation is 0.057%; the limit of detection is 2.09526 mg/mL; the limit of quantitation is 6.34928 mg/mL; and the range 40 mg/mL to 60 mg/mL. The quantitation of metamizole contents can be carried out by Fourier Transform Infrared spectrophotometric method with accurate and precise quantitation results.

Adenostemma lavenia (L.) is one of the medicinal plants on Nias Island that is used to treat many symptoms including cough, fever and diarrhea. Empirical data of this plant suggests that these medicinal benefits can be attributed to its antibacterial and antioxidant properties, as well as the total flavonoids contained within it, but research on this is still limited. Adenostemma lavenia (L.) was extracted with ethanol, while the antibacterial properties were measured using the disc method. Antioxidant testing was conducted with the DPPH (1,1-diphenyl-2-2picrihydrazyl) inhibition method. Total flavonoids were assessed using a modified AlCl3 method with a quercetin standard. Antibacterial test results of Staphylococcus aureus, Klebsiela pneumoniae, Propionibacterium acnes, Escherichia coli, Salmonella typhi, Bacillus cereus and Shigella sonnei with mean inhibition were 8.76 0.44, 8.13 0.72, 8.77 0.45, 6.47 0.54, 7.77 0.60, 7.33 0.44, 12.06 0.60 respectively. IC50 was 59.844 3.36 ppm. Total flavonoids were 13.566 0.021 mcg/g. The results of the antibacterial test of the ethanolic extract of Adenostemma lavenia (L.) were classified as moderate. The antioxidant activity and total flavonoids were in the high category, which can be attributed to the capture of free radicals to overcome disease.
