Background: The use of traditional medicinal plants Castanopsis costata in the management of diarrhea is an ancient practice in North Sumatra, Indonesia, but its safety and efficacy have not been examined scientifically in animal models. Therefore, this study aims to determine the antidiarrheal effect of C. costata leaf extract and fractions in vivo. Methods: The antidiarrheal activity was evaluated against animal models of diarrhea induced by castor oil, charcoal meal, and entero-pooling test. The extract group received doses of 25, 50, 100, and 200 mg/kg, while the fraction groups was treated with WFCC, EAFCC, and nHFCC, in doses of 50 and 100 mg/kg, respectively. The negative control received 10 mL/kg of the dissolving vehicle, while the positive was treated with loperamide 3 mg/kg. Results: The results showed that EECC doses of 200 mg/kg, WFCC, and EAFCC at 50 and 100 mg/kg, respectively significantly delayed the onset of diarrhea, while WFCC and EAFCC at 100 mg/kg significantly reduced the amount of wet feces output and total feces output. In addition, only WFCC and EAFCC (at 50 and 100 mg/kg, respectively) significantly reduced the mean weight of wet feces and total feces. The percentage of maximum diarrhea inhibition was observed at the EAFCC dose of 100 mg/kg. Based on the charcoal meal test results, only EAFCC significantly inhibited the distance traveled by charcoal meal and reduced the peristaltic index at a dose of 100 mg/kg, while the percentage decrease in gastrointestinal motility was 46.87\%. Similarly, in the entero-pooling test, WFCC and EAFCC significantly reduced the volume and weight of intestinal contents at a dose of 100 mg/kg, respectively. Conclusion: The results confirm that the extract and fractions of C. costata have antidiarrheal activity. Therefore, this study provides scientific support for the traditional use of C. costata in treating diarrhea.

Background: The development of serum preparations containing natural ingredients for sun protection is growing rapidly. Jamblang (Syzygium cumini) leaves are rich in phenolic compounds that can inhibit free radicals causing premature aging. Therefore, this study aims to determine the potential of S. cumini serum extract as sun protection. Methods: The extract was prepared and included in the serum base. The formulations were evaluated for rheological, pH, dispersion coefficient, and stability examinations. Furthermore, Sun Protection Factor was tested using a UV-Vis spectrophotometer. Results: The test of phytochemical compounds showed the presence of alkaloids, flavonoids, polyphenols, tannins, saponins, quinones, monoterpenoids, sesquiterpenoids, triterpenoids, and steroids. The result also showed that all serum formulations met the predetermined requirements. Furthermore, the extract has protective activity against ultraviolet rays, which was indicated by the SPF value. The higher the dose of S. cumini extracts in the serum formulation, the higher the value obtained. Formulations 1, 2, and 3 have SPF of 9.35{\textpm}0.11, 13.26{\textpm}0.16, and 26.05{\textpm}0.31, respectively. This indicates that they all met the Indonesian National Standard, that a sun protection preparation must have a minimum protection factor of 4. Conclusion: S. cumini extract serum has the potential to be developed as a new sun protection agent against ultraviolet radiation. However, further studies are still needed to determine the mechanism of its constituent active compounds.

The growth and spread of resistance to all first-line antimalarial drugs used in the treatment of malaria today has caused many problems in eradicating malaria in various countries in the world. Researchers have begun to look for candidates for new antimalarial drug compounds derived from natural products that have been scientifically proven to have antimalarial activity. This is done to replace antimalarial drugs that are currently experiencing resistance. Some active compounds that have been successfully isolated from various plants, including curcumin, kaempferol, piperine, andrographolide, α-mangostin, catechin, luteolin and betulinic acid, have been scientifically tested to have antimalarial activity with different mechanisms of action.

Background: Cerebral malaria (CM) is one of the most severe complications of Plasmodium falciparum infection and the leading cause of death from malaria in endemic areas. Natural products with antioxidant and anti-inflammatory activities have become valuable alternative therapeutic options in CM treatment. Therefore, this study aimed to investigate the neuroprotective effects of curcumin and kaempferol in experimental cerebral malaria (ECM) in mice infected with Plasmodium berghei ANKA (PbA). Methods: After PbA infection, mice were divided into 9 groups, namely Group I (negative control (NC)) with 0.5\% HPMC, Group II received chloroquine 20 mg/kg, Group III (normal) with aquadest, Groups IV, V, and VI received curcumin at doses of 20, 40, and 80 mg/kg, respectively, Groups VII, VIII, and IX received kaempferol at doses of 20, 40, and 80 mg/kg, respectively. The antimalarial activity was evaluated using Peter{\textquoteright}s four-day suppressive test. This was conducted to determine the \% parasitemia, survival rate, AST and ALT, blood-brain barrier (BBB) leakage, and neurobehavioral disorders in mice with CM. Results: The results showed that all treatments had significant antimalarial activity, with the \% suppression depending on the dose. It also indicates that PbA-infected mice had a survival rate of 11-19 days after infection, which was higher than those in the NC group. This suggested that curcumin and kaempferol have a protective effect on the survival of PbA-infected mice. Furthermore, they significantly reduced the AST and ALT concentrations in the sample compared to the NC group. The same was observed in cerebral vessel extravasation, where the Evans Blue stain assay showed significantly less dye extravasation in the brains of PbA-infected mice treated with curcumin and kaempferol. This indicated better-protected integrity of the BBB. Additionally, the results also demonstrated a decrease in neurological disorders arising during ECM in the group treated with curcumin and kaempferol. Conclusion: Considering these results, it is concluded that treatments with curcumin and kaempferol could improve animal survival, prevent AST and ALT elevations, as well as protect the BBB and neurobehavioral disorders associated with CM in PbA-infected mice.

Background: In North Sumatra, Castanopsis costata is commonly used by traditional practitioners for the treatment of diabetes mellitus, however, no studies have been carried out to substantiate this practice. Therefore, this study aims to evaluate the anti-diabetic activity of extract and fractions of C. costata leaves in mice with alloxan-induced diabetes. Methods: Swiss albino mice with alloxan-induced diabetes, were acquired and subjected to the experimental evaluations. Subsequently, the fasting blood glucose levels of the diabetic mice groups treated with glibenclamid, extract and fractions, as well as the untreated group, were evaluated after two weeks of therapy. Results: Based on the results, the ethanolic extract of C. costata considerably reduced the mice{\textquoteright}s blood glucose levels in a dose-dependent manner, at dosages of 25, 50, 100, and 200 mg/kgBW (\% DBGL: 21.10\%, 46.36\%, 58.94\%, and 60.93\%, respectively). In addition, the water fraction of C. costata leaves produced a greater reduction in blood glucose levels (\% DBGL: 78.93\%), compared to the ethyl acetate and n-hexane fractions (\% DBGL: 67.06\% and 58.83\%), respectively. Meanwhile, treatment with the antidiabetic drug, glibenclamide (5 mg/kgBW) produced a 50.75\% reduction in blood glucose levels. Conclusion: Based on the findings, the extract and fractions of C. costata leaves were concluded to exhibit significant anti-diabetic activity. This supported the claim that traditional practitioners in North Sumatra use the plant extract for diabetes treatment.
