Abstract

An imbalance of free radicals in the body can cause a health condition known as oxidative stress. Oxidative stress is a condition in which free radicals and antioxidants in the body are out of balance. Oxidative stress can be overcome with natural antioxidants. This study aims to determine the antioxidant activity indicated by the IC50 value of the extract of bamboo ater shoots (Gigantochloa atter Kurz) extracted with different solvent polarities. The extraction process was carried out by the maceration method using 96% alcohol solvent, n-Hexane, and ethyl acetate. Each extract was then subjected to phytochemical screening tests, including flavonoids, steroids, alkaloids, tannins, saponins, and terpenoids. Analysis of antioxidant activity in this study was carried out using the DPPH (2,2-diphenyl-1-picrylhydrazyl) method. The results of phytochemical screening showed significant differences among each solvent, where the 96% alcohol solvent showed the most complete phytochemical screening results. Based on the results of the study, it can be concluded that bamboo ater shoots have antioxidant activity, and solvent polarities affect the IC50 value shown. The 96% alcohol extract of bamboo ater shoots has antioxidant activity with an IC50 value of 39.22 µg/mL, the extract of bamboo ater shoots with ethyl acetate solvent is 56.19 µg/mL, and the extract of bamboo ater shoots with n-Hexane solvent is 69.77 µg/mL.

Abstract

Red guava (Psidium guajava L.) contains natural antioxidants that help neutralize free radicals originating from radiation, pollution, and harmful chemicals. This study aimed to identify secondary metabolites and determine the IC₅₀ values of ethanol extract and various fractions of red guava peel and fruit. Four solvents were used ethanol extract, ethyl acetate fraction, n-hexane fraction, and water fraction. Each sample was tested at concentrations of 20, 40, 60, 80, and 100 ppm. Vitamin C, at concentrations of 2, 4, 6, 8 and 10 ppm, served as a positive control. Antioxidant activity was evaluated using the DPPH method with a UV-Vis spectrophotometer at a wavelength of 516 nm and an incubation time of 30 minutes. Phytochemical screening showed that all extracts contained alkaloids, flavonoids, and tannins. The IC₅₀ values obtained were: ethanol extract peel 62,4719 ppm, ethanol extract fruit 44,0035 ppm, ethyl acetate fraction peel 56,7955 ppm, ethyl acetate fraction fruit 46,4394 ppm, n-hexane fraction peel 113,9311 ppm, n-hexane fraction fruit 114,4767 ppm, water fraction peel 104,0284 ppm, and water fraction fruit 76,5801 ppm.

Abstract

Breast cancer is a cancer with a high prevalence and mortality rate in women. One of the main therapies for hormone receptor-positive patients isAdjuvant Endocrine Therapy (AET) in the form of tamoxifen, either alone or in combination. The study aims to determine patient characteristics and patterns of hormonal therapy use.breast cancer patients at Dr. Moewardi Regional Hospital, Surakarta. The study used a randomized controlled study design.cross sectional with technique purposive samplingThe study subjects were 64 breast cancer patients undergoing tamoxifen therapy for at least one month. Data were obtained from medical records and questionnaires, then tested using Chi-Square see the relationship between variables. The results of the study showed that the majority of patients were aged <50 years (60.9%) and were in advanced stages (III–IV) at 57.8%. The most common type of therapy was a combination of chemotherapy and hormones (51.6%), while single hormonal therapy was used in 48.4% of patients. The most frequently used chemotherapy regimen was a combination of Cyclophosphamide & Epirubicin, while the most common hormonal therapy was Tamoxifen + Zoladex. Bivariate analysis showed a significant relationship between age and type of therapy and stage and type of therapy (p<0.05).

Abstract

Daun rambusa (Passiflora foetida L) dikenal memiliki berbagai khasiat herbal yang dapat dimanfaatkan sebagai bahan aktif dalam sediaan gel. Sediaan gel dipilih karena memiliki penetrasi obat ke dalam kulit lebih baik serta waktu kontak lebih lama dibandingkan sediaan topikal lainnya. Tujuan penelitian ini untuk mengetahui pengaruh variasi konsentrasi Na-CMC terhadap uji stabilitas dan hedonik sediaan gel ekstrak daun rambusa. Metode yang digunakan dalam penelitian ini meliputi formulasi sediaan gel dengan tiga variasi konsentrasi Na-CMC (2%, 2,5%, dan 3%), pengujian stabilitas dengan cycling test selama 6 siklus pada suhu 4⁰C dan 40⁰C, serta uji hedonik. Uji stabilitas mencakup pengamatan perubahan organoleptik, homogenitas, nilai pH, daya sebar, daya lekat, dan viskositas. Sedangkan uji hedonik melibatkan penilaian responden terhadap warna, aroma, dan tekstur gel. Analisis data dilakukan dengan One Way ANOVA untuk melihat perbedaan antara formula dan T-Test Dependent untuk mengetahui stabilitas sediaan gel ekstrak daun rambusa. Hasil penelitian menunjukkan variasi konsentrasi Na-CMC pada ketiga formula sesuai dengan standar terhadap uji organoleptik, homogenitas, pH, daya sebar, daya lekat, dan viskositas. Hasil statistik menunjukkan nilai <0,05 yang berarti terdapat perbedaan signifikan pada uji stabilitas dan hedonik terhadap variasi konsentrasi Na-CMC. Gel ekstrak daun rambusa menunjukkan sifat yang stabil, kecuali FI yang kurang stabil pada viskositas. FIII mendapatkan penilaian tertinggi terhadap parameter warna dan aroma, sedangkan pada tekstur lebih disukai FI.

Abstract

Acne is a skin disease where the oil glands are blocked by dirt that can be infected by bacteria. One way to cure acne is by using compounds that have antibacterial effects. Butterfly pea flowers contain compounds that are believed to inhibit bacterial growth at a certain percentage. The purpose of this study was to determine the antibacterial effectiveness of butterfly pea flower extracts and fractions in certain concentrations. This type of research uses experimental. This study was divided into 6 groups with 4 different concentrations, namely positive control (Gentamicin), negative control (DMSO 10%), Butterfly pea flower extract (15%, 20%, 30%, 40%), Aquadest Fraction (15%, 20%, 30%, 40%), N-hexane Fraction (15%, 20%, 30%, 40%), and Ethyl acetate fraction (15%, 20%, 30%, 40%). The results of the bacterial inhibition zone data were analyzed using SPSS 26 with a confidence level of 95%. The results of this study indicate that the extract and fraction of butterfly pea flowers provide antibacterial effects on the growth of staphylococcus aureus bacteria at concentrations of 15%, 20%, 30%, and 40%. The best inhibition zone is in the ethanol extract of butterfly pea flowers with an average inhibition zone of 9.3 mm at a concentration of 40%.
