Abstract

According to WHO, as many as 13 million children in the world die every year and most of these deaths are in developing countries, where ISPA is one of the main causes of death by killing as many as 4 million children each year. Bronchitis ranks 6th out of 10 causes of death. However, Indonesia still has no reports on exact figures regarding this disease. This study aims to determine the accuracy of the use of antibiotics in pediatric patients with acute bronchitis based on the Gyssens method at RSIA Zainab Pekanbaru City. This type of research was non-experimental with data collection using a purposive sampling technique retrospectively. The results of the study based on a qualitative evaluation of the use of antibiotics in pediatric acute bronchitis patients at RSIA Zainab Pekanbaru City using the Gyssens method showed the quality of rational use of antibiotics found that 64 patients were declared rational ( category 0) and 5 patients were declared irrational. If possible further research regarding the rationality of using antibiotics in pediatric acute bronchitis patients at RSIA Zainab Pekanbaru City can be carried out using the DDD method or with a prospective approach so that monitoring of the patient's condition progress can be carried out from day to day.

Abstract

Antioxidants and free radicals are topics that are increasingly discussed in the field of health and lifestyle. Free radicals, which result from oxidative stress, are known to play a role in the development of many serious diseases, such as cancer, cardiovascular disorders and premature aging. Antioxidants are able to neutralize free radicals, thus having the potential to prevent or reduce the impact of these diseases. This study aims to evaluate the antioxidant activity of ethanol extract of pandan wangi leaves (Pandanus amaryllifolius Roxb) using the DPPH (2,2-diphenyl-1-picrylhydrazyl) method and determine the IC50 value as an indicator of effectiveness. Experimental methods were used to analyze antioxidant activity, with DPPH assays performed using a UV-Vis spectrophotometer. The results showed that the ethanol extract of pandan leaves had an IC50 value of 180.21 µg/mL, which was slightly lower than vitamin C as a positive control with an IC50 value of 136.03 µg/mL. Nevertheless, the antioxidant activity of pandan leaf extract is still in the moderate category, indicating its potential as a source of natural antioxidants. This study also emphasizes the importance of technical factors, such as temperature, incubation duration, and solvent quality, in influencing the test results. This study opens up opportunities for further development in the optimization of extraction and utilization of pandan wangi leaves as a natural ingredient to fight oxidative stress.

Abstract

The yellow sirsak plant (Annona montana) is an annonaceae family which has been used by the community as traditional medicine properties such as treating diarrhea, vitamin C deficiency and treating boils. This study aims to determine the cytotoxic activity of the larvae of Artemia salina Leach shrimp by using the BSLT method after giving extracts from the leaves and fruit of yellow sirsak (Annona montana). The results showed that the LC50 value of the n- hexane extract of yellow sirsak leaves was 45,84 µg/mL, the ethyl acetate extract of yellow sirsak leaves was 26,44 µg/mL and the ethanol extract of yellow sirsak leaves was 13,99 µg/mL. The n-hexane extract of yellow sirsak fruit was 31,46 µg/mL, the ethyl acetate extract was 40,45 µg/mL and the ethanol extract of the yellow sirsak fruit was 19,84 µg/mL. The mixture of n-hexane leaves and yellow sirsak fruit was 29,91 µg/mL, the ethyl acetate extract mixture of yellow sirsak leaves and fruit was 21,71 µg/mL and the mixture of ethanol extract and yellow sirsak fruit was 14,75 µg/mL. Based on the research results, it can be concluded that the ethanol extract of yellow sirsak leaves shows the most active cytotoxic activity with an LC50 value of 13,99 µg/mL.

Abstract

Uncaria nervosa Elmer leaves are known to contain bioactive compounds with potential as natural drug candidates, yet their pharmacokinetic profiles, drug-likeness, and molecular affinity toward target proteins remain limitedly explored. This study aimed to evaluate the pharmacokinetic properties, drug-likeness, and molecular interaction potential of bioactive compounds from the ethanol extract of Uncaria nervosa leaves. An in silico approach was employed using SwissADME to analyze pharmacokinetic parameters (absorption, distribution metabolism, and excretion) and drug-likeness based on Lipinski’s and Veber’s rules, followed by molecular docking against proteins 6O0K and 2W3L using MOE software. The results showed that most compounds exhibited high gastrointestinal absorption, did not inhibit major CYP enzymes, and several complied with drug-likeness rules. Docking analysis revealed that ceratodictyol displayed the closest binding energy to the positive controls (doxorubicin and obatoclax), indicating strong molecular affinity, while N-formamide showed superior pharmacokinetic and drug-likeness properties. In conclusion, the combination of pharmacokinetic and docking data highlights ceratodictyol as the main candidate supported by N-formamide as a potential compound, suggesting that Uncaria nervosa leaf extract may serve as a promising natural source for anticancer drug development.

Abstract

Uncaria guianensis is a medicinal plant from the Rubiaceae family, known for its wide range of pharmacological activities, particularly as an anti-inflammatory and immunomodulator. The leaves are rich in secondary metabolites such as alkaloids, flavonoids, tannins, and triterpenoids, whose potential is strongly influenced by the extraction method employed. This study aimed to compare the yield and characteristics of 70% ethanol extracts of Uncaria guianensis leaves obtained through four extraction methods: maceration, percolation, soxhlet extraction, and sonication. Leaf samples were collected from Kampar Regency, Riau, processed into powdered simplicia, and extracted using 70% ethanol. The results of the study showed that the soxhletation method produced the highest yield, namely 65.16%, followed by the maceration, percolation, and sonication methods with yields of 46.42%; 38.20%; and 35.82%, respectively. Phytochemical screening confirmed that all extracts tested positive for the presence of flavonoids, alkaloids, tannins, saponins, steroids, and triterpenoids. In terms of physicochemical characteristics, the soxhlet extract exhibited the best quality, with the lowest ash content (1.00%) and moisture loss (0.53%). In conclusion, soxhlet extraction is the most effective method for producing 70% ethanol extracts of Uncaria guianensis leaves, both in terms of quantity (yield) and quality (ash content and moisture loss).

Abstract

Red shoot leaves are known to contain secondary metabolic compounds such as alkaloids, flavonoids, tannins, triterpenoids, steroids, saponins, and phenolic compounds. Flavonoids are known to have cardioprotective activity, including the ability to inhibit platelet aggregation. This study aims to determine the potential of red shoot leaf extract (Syzygium myrtifolium Walp.) as an anticoagulant. The method used is the determination of coagulation time, carried out on days 0, 3, and 6, following the initial wounding of the mice’s tails. The tail is wounded using a sterile lancet at a distance at 2 cm from the tip, and blood is subsequently absorbed using a capillary tube. Coagulation time is measured by observing the formation of fibrin threads on the broken sections of the capillary tube every 15 seconds. Coagulation time is the time required for the formation of the fibrin thread. The study results on day 6 showed that the 100 mg/KgBW dose group of red shoot leaf ethanol extract demonstrated an effect of increasing coagulation time equivalent to the 100 mg acetosal group. Meanwhile, the 125 mg/KgBW dose group of red shoot leaf ethanol extract showed a stronger effect than the 100 mg acetosal group.
