The increasing global prevalence of oxidative stress-related diseases such as cardiovascular disease, diabetes, and neurodegenerative disorders underscores the importance of developing effective antioxidant strategies. In this study, samples of ethanol extract from Bridelia micrantha (Melandean) leaves were used which were then evaluated using the DPPH (2,2-diphenyl-1-picrylhydrazyl) test, a method that is widely known for assessing free radical scavenging activity. The ethanol extract sample was obtained through maceration with a yield of 15.84%. Based on the DPPH test, it shows that the extract has dose-dependent inhibition of DPPH radicals, with a maximum inhibition of 66.13% at a concentration of 25 ppm. The IC50 value, calculated from regression analysis, confirmed the antioxidant potential of the extract, although it was less effective than that of vitamin C, which was used as a positive control. These findings suggest that Bridelia micrantha leaves, rich in phytochemicals such as flavonoids, tannins, and saponins, have the potential as a source of natural antioxidants for managing oxidative stress-related health conditions.

Saus tomat adalah salah satu bahan makanan yang banyak dikonsumsi di berbagai belahan dunia, termasuk Indonesia. Meskipun memiliki cita rasa yang lezat, terdapat kekhawatiran terkait penggunaan bahan kimia berbahaya, seperti Rhodamin B, yang dapat membahayakan kesehatan. Rhodamin B merupakan pewarna sintetik yang dilarang penggunaannya dalam makanan karena dapat menyebabkan gangguan organ hingga kanker. Kegiatan pengabdian masyarakat ini bertujuan untuk mengembangkan metode alternatif dalam mendeteksi keberadaan Rhodamin B pada saus tomat menggunakan detergen sebagai ekstraktor dan kunyit (Curcuma longa) sebagai indikator alami khususnya mahasisiwa dan ibu-ibu rumah tangga di Desa Bagu. Metode pelaksanaan meliputi penyuluhan, demonstrasi, dan praktik langsung pembuatan. Hasil kegiatan menunjukkan bahwa peserta sangat antusias dan mampu memahami serta mempraktikkan cara deteksi Rhodamin B pada saus tomat secara mandiri. Diharapkan kegiatan ini dapat meningkatkan kesadaran masyarakat dalam memilih makanan yang aman dikonsumsi serta mendorong gaya hidup sehat dalam keluarga

Ashitaba (Angelica keiskei Koidz.) is a medicinal plant known to be rich in active flavonoid compounds, particularly chalcones, which exhibit antioxidant, anti-inflammatory, and antidiabetic activities. This study aimed to determine the total flavonoid content in Ashitaba leaf extract obtained from Sembalun Village using UV-Vis spectrophotometry. The extract was obtained by maceration using 96% ethanol. Quantitative analysis was performed at the maximum wavelength of 415 nm, with quercetin as the standard. Calibration curves were prepared using quercetin concentrations of 20, 30, 40, 50, and 60 ppm on the X-axis, with absorbance values of 0.297, 0.337, 0.436, 0.509, and 0.588 on the Y-axis, resulting in the regression equation Y = 0.0094x + 0.0472 with a correlation coefficient (r) of 0.9677, indicating a linear relationship between concentration and absorbance. Absorbance values of the sample measured in triplicate were 0.661, 0.634, and 0.676, yielding an average total flavonoid content of 25.948 mgQE/g in Ashitaba leaf extract.

Antioxidants are compounds that can donate hydrogen atoms to free radicals so that they can stop the chain reaction and convert free radicals into a stable form. custard apple leaves are known to have various benefits, one of which is as an antioxidant. This study aims to determine the potential antioxidant activity contained in custard apple leaves (Annona Squamosa L) with polar, semi-polar and non-polar fractions through the DPPH method. The sample used in this study was custard apple leaf extract (Annona Squamosa L) extracted with 96% ethanol solvent, and phytochemical screening tests, fractionation, antioxidant activity tests using UV-Vis spectrophotometer and IC50 value calculation using Microsoft exel were carried out. The results of the sample phytochemical screening showed that there were four compounds, namely phenolics, flavonoids, tannins and alkaloids while the results of the antioxidant activity test had a very strong category with the IC50 value of ethyl acetate, n-hexane and aquadest fractions of (3.950, 4.651, and 11.009 ppm) and the activity results of the IC50 value of custard apple leaf ethanol extract with a strong category of 22.280 ppm.

Postpartum psychosis (PPP) is a severe mental health disorder characterized by the acute onset of psychotic symptoms such as delusions, hallucinations, and mood disturbances shortly after childbirth. Although it affects 1-2 per 1,000 women globally, its impact is particularly severe in low-resource settings like Nigeria, where cultural stigma, limited mental health infrastructure, and low awareness lead to under diagnosis and poor outcomes. This study aimed to assess the awareness of puerperal psychosis among pregnant women attending the Antenatal Care (ANC) unit at Abubakar Tafawa Balewa University Teaching Hospital (ATBUTH) in Bauchi, Nigeria. A descriptive survey design was employed, and data were collected from 129 respondents selected via simple random sampling, using a structured questionnaire. The results indicated that while a majority (71.32%) of respondents had heard of postpartum psychosis, there was a significant deficit in detailed knowledge. Only 56.53% could accurately define it as a severe mental disorder post-childbirth, and misconceptions about causes and symptoms were common. Key risk factors such as sleep deprivation, family history of bipolar disorder, and impaired mother-infant bonding were correctly identified by most. For prevention, respondents strongly endorsed educational programs, postnatal screening for high-risk women, frequent ANC visits, family support, and ensuring adequate rest. The study concludes that despite basic recognition of PPP, profound knowledge gaps persist among pregnant women in this setting. It underscores the urgent need for integrated, educational interventions during antenatal care and the routine inclusion of mental health screenings to facilitate early identification, management, and ultimately, improved maternal and infant outcomes in Northern Nigeria.
