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.

Key words: Malaria, Antimalarial, Curcumin, Kaempferol, Piperine, Andrographolide, α-Mangostin, Catechin, Luteolin, Betulinic acid.

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.
