Abstract

Forest Cempedak Seeds (Artocarpus champeden Lour.) Are types of seeds that are underutilized by humans. Forest Cempedak Seed Flour has nutritional content of carbohydrates, fats, and proteins that can be processed as ingredients for food. This study aims to determine the carbohydrate content of Forest Cempedak Seeds (Artocarpus champeden Lour.) Conducted by the Copper-Iodometric method using a luff schoorl reagent. From the research that has been carried out obtained levels of carbohydrates in Cempedak Seeds (Artocarpus champeden Lour.) of 38.016%.

Abstract

For humans, carbohydrates are a crucial nutrient that the body uses to produce energy. Additionally, carbohydrates aid in the body's digestion of extra protein. White rice flour (Oryza sativa L.) is a common energy source in the community with a high carbohydrate content. This research was done to find out how different hydrolysis times affected the amount of carbohydrates in white rice flour (Oryza sativa L.). The Schoorl Luff method is used to determine the carbohydrate content of commercial white rice flour. HCl 1 N was used as a catalyst to hydrolyze white rice flour, with different hydrolysis periods of 60 minutes, 90 minutes, 120 minutes, 150 minutes, and 180 minutes. A schoorl luff, a source of Cu2+, was used to assess the hydrolysis results and titrated iodometrically. With a time of 180 minutes and a weight-to-water ratio of 63.99%, the findings of determining the ideal carbohydrate content in commercial white rice flour were obtained.

Abstract

Due to the high concentration of secondary metabolites present in nearly every part of the plant, black turmeric (Curcuma caesia Roxb.), a traditional medicinal plant, may provide a natural supply of antioxidants. The objective of this research is to determine the total phenolic content of the black turmeric rhizome ethanol extract using UV-Vis spectrophotometry. The extraction was performed by macerating the material in a solution consisting of 70% ethanol. We employed the Folin-Ciocalteu method to ascertain the total phenolic content, which was then represented as gallic acid equivalent (GAE). The research revealed that there were 192 mg GAE/g of total phenolic content in the ethanol extract of black turmeric rhizome. According to the metrics measuring total phenolic content, the black turmeric rhizome ethanol extract may have antioxidant properties. This study provides important information about black turmeric's antioxidant potential which can be used to develop herbal products based on this plant.

Abstract

Alopecia merupakan gangguan pertumbuhan rambut yang berkaitan dengan stres oksidatif dan inflamasi kronis pada folikel rambut. Terapi konvensional seperti minoxidil dan finasterid memiliki keterbatasan efektivitas serta potensi efek samping, sehingga diperlukan alternatif berbasis bahan alam yang lebih aman. Penelitian ini bertujuan mengevaluasi aktivitas biologis dan mutu fisik emulgent topikal yang mengandung purifikasi ekstrak daun sidr (Ziziphus spina-christi L.) dan biji kemiri bakar (Aleurites moluccanus L.) sebagai kandidat fitoterapeutik penumbuh rambut. Ekstraksi dilakukan menggunakan metode ultrasound-assisted extraction dan sokhletasi, dilanjutkan pemurnian berbasis air. Analisis HPLC menunjukkan kandungan utama berupa rutin (245 mg/L), quercetin (6,8 mg/L), dan asam galat (47 mg/L) pada ekstrak sidr, serta quercetin (27 mg/L) pada ekstrak kemiri bakar. Evaluasi fisik sediaan menunjukkan pH fisiologis (5,0–6,7), daya sebar optimal, viskositas stabil, serta stabilitas baik pada uji freeze–thaw. Uji in vivo selama 21 hari menunjukkan bahwa formula kombinasi secara signifikan meningkatkan pertumbuhan rambut dibandingkan basis dan minoxidil 2% (ANOVA, F = 9,28; p = 0,0003). Efek ini berkaitan dengan aktivitas antioksidan dan antiinflamasi flavonoid yang mendukung perpanjangan fase anagen.
