Abstract

People use Kemloko Fruits as sweets and some also use it as a herbal medicine to reduce uric acid. The sour-tasting Kemloko fruit contains a lot of ascorbic acid. Ascorbic acid and ingredients contained in it have the effect of preventing or reducing uric acid levels. The aim of this research was to treat the antioxidant effect and inhibitory of the xanthine oxidase enzyme Kemloko Fruit extract, as well as determine the phenolic total and flavonoid total levels. The method used to make Kemloko fruit extract uses maceration with ethanol 96% solvent. The phytochemical screening method uses an in-tube reaction for flavonoid content using the Shinoda test, alkaloids using the Dregendorf reagent, saponins using the foam test and terpenoids/steroids using the Liebermann Burchard reagent. Meanwhile, the methods for determining phenolics and flavonoids total are the colorimetric used spectrophotometry UV-Vis, the DPPH methods for antioxidant assay, and measurenment of inhibiting xanthin oxidase activity using a microplate at a wavelength of 375 nm. Qualitative data produced by the ethanol extract of Kemloko fruit contains tannins, flavonoids, alkaloids, terpenoids, saponins and glycosides. Meanwhile, Quantitative data showed that the phenolic and flavonoid total levels were 1465.63±0.003 mgGAE/g extract and 9.52±0.001 µg/mL, respectively, as well as the IC50 for xanthin oxidase enzyme inhibition of 20.65 µg/mL and the IC50 antioxidant power of 9.49 ±0.0007 µg/mL. Kemloko fruit ethanol extract contains tannins, flavonoids, alkaloids, terpenoids, saponins and glycosides has inhibitor activity against xanthine oxidase and antioxidant is a strong.

Abstract

Purple corn is a plant belonging to the Poaceae family which has the Latin name Zea mays L. var. ceratina Kuleshov. Purple corn contains anthocyanins which are beneficial for human health as antioxidant agents. Anthocyanins have low stability at high heat and dissolve easily in water. The purpose of this study was to determine the total anthocyanin levels and antioxidant activity of fresh, steamed, and boiled purple corn. This research was conducted qualitatively using thin-layer chromatography with the mobile phase n-Butanol: ethyl acetate: distilled water (4:1:5) and quantitatively using the differential pH method and the antioxidant activity test using the DPPH method. The results obtained from the TLC test showed anthocyanin standard 0.72; fresh purple corn 0.71; steamed purple corn 0.71, and boiled purple corn 0.71. In the qualitative test of total anthocyanin levels using the differential pH method, the total anthocyanins in fresh purple corn were 235,45 mg/100 g; steamed purple corn of 38,908 mg/100 g, and boiled purple corn of 20,42 mg /100 g. From the antioxidant test with the DPPH method, it was obtained that the best IC50 value in fresh purple corn samples of 33.92 (very strong); steamed purple corn was 124.33 (medium) and boiled purple corn was 126.26 (medium).

Abstract

Ikan mujair (Oreochromis mossambicus) merupakan ikan yang tahan terhadap kondisi lingkungan dan mudah ditemukan yang apabila terpapar logam berat serta dikonsumsi dalam jangka panjang akan menimbulkan efek neurotoksik, karsinogenik, mutagenik ataupun teratogenik bahkan sampai kematian. Cd2+ dan Pb2+ merupakan logam berat berbahaya yang bersifat toksik serta dapat mencemari organisme perairan. Penelitian ini bertujuan untuk mengetahui kadar Cd2+ dan Pb2+ pada ikan mujair di tambak Kota Pekalongan. Sampel berasal dari tambak Jeruksari, Panjang, dan Slamaran. Analisis kadar logam berat menggunakan metode AAS (Atomic Absorption Spectrophotometry). Hasil penelitian menunjukkan ikan mujair di tambak Jeruksari, Panjang dan Slamaran mempunyai kadar Cd2+ sebesar 0,07; 17,38 dan 0,02 mg/Kg, serta kadar Pb2+ sebesar 10,26; 6,08 dan 8,62 mg/Kg. Kadar Cd2+ pada tambak Panjang melebihi ambang batas yang ditetapkan oleh BPOM yaitu 0,1 mg/Kg, sedangkan kadar Pb2+ pada ketiga tambak melebihi ambang batas yang ditetapkan oleh BPOM yaitu 0,2 mg/Kg.

Abstract

Serum is a cosmetic that has received great attention from the industry, but the main challenges are appearance, transparency and public acceptance of herbal active ingredients. On the other hand, herbal cosmetics, such as those using lime peel, are also growing. This study aims to determine the antioxidant activity of lime peel made in a nano extract serum preparation. The method for making nano extracts uses ionic gelation with PSA (Particle Size Analyzer) and Zeta Potential characterization. The concentration of nano serum of lime peel ethanol extract used was 0.5%; 1%; and 3%. Meanwhile, the antioxidant activity testing method uses DPPH and data analysis applied one-way ANOVA then by Tukey test. The results of the nano extract serum formulation using organoleptic testing are transparent, thick and liquid, odorless, and feel moist on the skin. The results of nanoparticle characterization using PSA measurements with three replications were 295.1; 320.3; 385.4 nm and the results of testing the zeta potential of nanoparticles with three replications, namely 3.2; 3.4; 6.0mV. Furthermore, the results of the antioxidant activity test on the basis of the preparation formula are classified as weak (IC50 value of 156.22 μg/mL); Meanwhile, preparation formula with a concentration of 0.5%; 1%; 3% are considered very strong (IC50 value of 46.39 μg/mL; 41.06 μg/mL; 36.27 μg/mL). The results of data analysis consider significance of p value below 0.05. The conclusion is nano lime peel extract meets the requirements and the serum preparation meets the requirements and has antioxidant activity.

Abstract

Significant efforts are necessary to prevent the spoilage of fatty acid-rich foods as a result of lipid oxidation. Active packaging is a technology that employs packaging films containing antioxidants to increase the stability of perishable foods susceptible to oxidation. This preliminary study aimed to incorporate tannic acid (TA) into a chitosan/κ-carrageenan (Chit/κ-Car)-based polyelectrolyte complex (PEC) films and evaluate their antioxidant release profile. The composition of Chit/κ-Car, glycerol (gly), and TA in PEC films were also investigated in this preliminary study as factors influencing the mechanical properties of films and the antioxidant release profile. The prepared PEC films were identified by an FTIR spectrometer and examined through a mechanical property test. The DPPH method was used to assess the antioxidant property of the Chit/κ-Car-based PEC films. The infrared spectra revealed that PEC films were formed through the interaction between ꟷNH3+ of Chit and ꟷOSO3ꟷ of κ-Car. Increasing the κ-Car and TA compositions in the PEC films increased the tensile strength (TS) and water absorption capacity (WAC), but decreased the elongation (E). The release profile of TA from PEC films followed the Korsmeyer-Peppas model through the Fickian diffusion mechanism with n < 0.5. The antioxidant activity test of PEC films using the 1,1-diphenyl-2-picrylhydrazyl (DPPH) method revealed high antioxidant activity with radical scavenging activity (RSA) values up to 95.04%. As a result, the Chit/κ-Car-based PEC films have the potential to be developed as active packaging. Keywords: Active packaging, antioxidant, Chit/κ-Car-based PEC films, release profile, TA

Abstract

The leaves of henna are commonly used by local communities to treat burns, inflammation, and skin diseases. This plant contains lawsone (2–hydroxy-1,4-naphthoquinone) and various phenolic glycosides, flavonoids, tannins, alkaloids, and quinones, which are believed to contain antibacterial activity. This study aims to determine whether ethanol extracts from the leaves and stems of henna exhibit antibacterial activity and to assess their inhibitory effects against Staphylococcus aureus. The methods employed in this study include maceration and turbidimetric analysis. The extraction method was maceration with 96% ethanol as the solvent. The antibacterial activity was tested using the turbidimetric method with extract concentrations of 15%, 25%, and 30%. Chloramphenicol was used as a positive control, and NaCl served as a negative control. The results revealed that the leaf extracts of henna exhibited antibacterial activity in the leaves and stems of henna nails by comparing the average absorbance values before and after incubation. At concentrations of 15%, 25% and 30% of the leaves of henna na na experienced shedding after incubation which showed that the growth of bacteria had been inhibited. Meanwhile, in the henna nail stem extract, the concentration of 15% decreased after incubation and the concentration of 25%, 30% showed an increase in absorbance value after the incubation process.
