Abstract

This study is essential to analyze the toxicity and release of bioactive compounds in R. tuberosa L. extract microcapsules coated with gum Arabic and to provide information on the use of microcapsules as a drug delivery system with controlled release of active ingredients. Investigations focused on the effect of pH and timing on discharge kinetics, as well as toxicity evaluation. The release of active ingredients from microcapsules was carried out in medium variations, namely pH 2.2 and pH 7.4, with release durations of 30, 60-, 90-, 120-, and 150-min. Bioactive compounds were released by 59.23% at pH 2.2 and 58.21% at pH 7.4 within 150 min. The BSLT (brine shrimp lethal toxicity) assay was used using brine shrimp larvae (Artemia salina L.), resulting in a non-toxic classification as evidenced by an LC50 value of 5729 μg/mL. Microcapsules in optimum conditions were then characterized using FTIR (Fourier-Transform Infrared) and SEM (scanning electron microscopy) instruments. The FTIR analysis showed variations in functional groups in R. tuberosa L. extracts, gum Arabic, and microcapsules. Furthermore, the SEM examination highlighted the morphology of microcapsules that were mostly spherical.

Abstract

This study aims to investigate the microencapsulation of C. caudatus K. leaves extract under optimal conditions, focusing on its potential as a therapeutic option for type 2 diabetes. In order to determine the inhibitory effect on the α-amylase enzyme, which plays a crucial role in glucose metabolism, biological activity assays were performed. The procedure of effectively encapsulating the substance was achieved at a pH level of 6 using sodium alginate at a concentration of 2% (w/v), resulting in a 77.2% percentage of encapsulation. The experiment involving the inhibition of α-amylase exhibited an IC50 value of 69.44 ± 0.924 μg/mL, demonstrating the significant biological activity of the microcapsules. The bioactive substances encapsulated in the microcapsules were released during intervals 30-120 min, at pH conditions of 2.2 and 7.4. The release of bioactive substances was only 2.32 % after 120 minutes at a pH of 2.2, whereas it increased to 64.54 % at a pH of 7.4. This discovery indicates that the microcapsules contain the capability to be utilized for the regulated delivery of drugs. The findings of this research demonstrate the potential to develop herbal medicines with therapeutic properties through microencapsulation, providing an excellent opportunity for managing type 2 diabetes.

Abstract

Advanced drug delivery systems are required due to the increasing advancement in science and technology, with a common example being microencapsulation. This system is affected by the manufacturing conditions and slow release of bioactive compounds inside microcapsule. In general, phytochemicals in the edible plant, Cosmos caudatus Kunth, specifically flavonoids, offer several health benefits but are susceptible to degradation which reduces biological activities. Therefore, this study aimed to encapsulate extract using spray drying method, which can be used as wall material in Gum Arabic. Microencapsulated product was also tested for biological activities. The effect of microcapsule production was investigated, including the concentration of wall material and the stirring speed. Furthermore, the optimal conditions of microcapsule were selected based on the highest encapsulation efficiency. The results showed that a concentration of 4% (w/v) Gum Arabic and a stirring speed of 800 rpm were the optimal conditions, leading to a percentage release of 71.87%. Microcapsule under these conditions produced an IC50 value of 55.09 ± 0.57 ug/mL as an inhibitor of alpha-amylase enzyme. The characterization by scanning electron microscope (SEM) showed spherical forms with a mean diameter of 152.00 um. The bioactive substance in microcapsule was released at pH 2.2 and pH 7.4 for 30 to 120 min, with a percentage release of 38.05% and 95.14%, respectively. In conclusion, this study confirmed that microencapsulation played a crucial role in the development of plant extract with retained biological functions.

Abstract

Ruellia tuberosa L. leaf and root extracts have been investigated for their biological activity and potential health advantages, including their antidiabetic, antioxidant, and antidiuretic qualities. This research evaluates the freeze-drying microencapsulation of R. tuberosa L. extracts using gum Arabic, maltodextrin, and their combination as coating materials. The resulting microcapsules were tested for encapsulation efficiency, biological activity, and controlled release. Characterization techniques included scanning electron microscopy (SEM), Fourier-transform infrared (FTIR) spectroscopy, and particle size analysis (PSA). The choice of encapsulant significantly influenced encapsulation efficiency, morphology, and biological activity. Microcapsules using a combination of gum Arabic and maltodextrin exhibited more spherical shapes and smaller particle sizes than those using either material alone. Alpha-amylase inhibition tests showed that microcapsules effectively inhibit the enzyme, with the coating combination performing best, followed by gum Arabic and then maltodextrin. All microcapsules exhibit moderate antioxidant activity, again in the same order. The active compound release was greater at pH 7.4 compared to pH 2.2 from 0 to 120 min. Therefore, freeze-drying microencapsulation with biodegradable polymers is a viable method for delivering the health benefits of R. tuberosa L. extracts, yielding a convenient powder form suitable for drug delivery systems.

Abstract

Rodhamine B and Saccharin are often misused by food producers as food additive, which, if their use is not monitored, can produce free radicals that cause oxidative stress conditions in the body, leading to dangerous damage to the body. The addition of purple rosella in yoghurt can increase the functional value of the yoghurt, namely increasing the antioxidant content. The purpose of this study was to determine the benefits of giving purple rosella yoghurt in preventing damage to the duodenum and colon of (Rattus norvegicus) caused by Rodhamine B and Saccharin. This study used Completely Randomized Design (CRD) with 28 male R. novergicus, Wistar strain in aged 8-12 weeks. Group K was not given any treatment; R was given Rodhamine B, S was given Saccharin, KRS was given Rodhamine B and Saccharin, YR was given Rodhamine B and yoghurt, YS was given Saccharin and yogurt, YRS was given Rodhamine B, Saccharin and yogurt. The dose of Rodhamine B was 22.5 mg.kg-1, Saccharin was 157.77 mg.kg-1, and the volume of yoghurt was 1 mL.head-1. They were administered orally with a gastric tube for 14 days. The concentration of purple rosella extract added to yoghurt was 15% (v/v). Parameters were observed in histopathology of the duodenum and colon with the scoring method. Data analysis was done with the Kruskal-Wallis test followed by the Mann-Whitney test. The KRS group showed the heaviest damage, namely necrosis, villi erosion, and inflammatory cell infiltration of >75% of the total visual field in the duodenum and colon. The YR, YS, and YRS groups showed significant changes compared to the R, S, and KRS groups, namely necrosis, villous erosion, and inflammatory cell infiltration, which appeared to be 25-50% of the total visual field. However, this did not match the condition of group K, which appeared to be <25% of the total visual field. The provision of purple rosella yoghurt can prevent 50% damage to the duodenum and colon of Rattus novergicus due to Rodhamine B and Saccharin. Keywords: colon, duodenum, Rodhamine B, Saccharin, yoghurt.

Abstract

Purple rice is rich in ferulic acid, a phenolic acid abundant in rice. Ferulic acid (FA) has long been recognized for its anti-oxidant properties, which are linked to its skin anti-aging activity owing to its ability to scavenge free radicals and pro-tect cells from damage. Skin anti-aging activity could be assessed by inhibiting skin aging enzymes. However, there was limited information on the mechanism of FA inhibition of these enzymes. This study focused on the molecular interac-tion between purple rice FA and collagenase or tyrosinase, both with and without their substrates. The interaction be-tween FA (CID 445858), collagenase (2Y6I), tyrosinase (5M8M), collagenase substrate (CID 5486160), and tyrosinase substrate (CID 6057) was docked using Hex 8.0.0 Cuda with the default settings. Discovery Studio 2020 and LigPlot software were used to visualize the docking results. Ascorbic acid (CID 54670067) and kojic acid (CID 3840) were used as positive controls for collagenase and tyrosinase, respectively. Molecular docking revealed that FA formed electro-static, hydrogen, and hydrophobic bonds with all aging enzymes, substrates, and enzyme–substrate complexes. FA could bind to both free enzymes and free substrates, consequently attenuating enzyme–substrate bonding, and preventing the substrate from binding appropriately in its normal position. Molecular dynamics simulations demonstrated that FA formed a stable bond with tyrosinase, similar to kojic acid, although the bond with collagenase was less stable. However, the pattern of each parameter during the simulation was comparable with that of ascorbic acid. The current study indicated that the FA from purple rice had the potential to act as an inhibitor of skin aging en-zymes and could be developed as a skin anti-aging candidate

Abstract

The Indonesian purple rice (IPR), a crossbreeding of black and white rice, is a potential source of ferulic acid. Up to this point, the genomic similarity between the crossbreeding and its parentals has not been determined, particularly in genes involved in ferulic acid biosynthesis. In this present work, we analysed the profile of Oryza sativa caffeic acid-O-methyltransferase (OsCOMT) gene in IPR. The genomic DNA was extracted by CTAB method, then amplified with a specific primer of OsCOMT gene. The amplicon was sequenced by Sanger method and confirmed by geneID NC_029259.1. The IPR showed an amplicon of 708 bp sequence of the OsCOMT gene, indicating the gene involved in ferulic acid biosynthesis. The IPR gene profile is similar to the parentals, but there are variations in point mutations that distinguish it from the parentals. Aspartic acid was changed to Glutamine by mutations at positions 52, 69, and 79. We suggest that IPR has a novel OsCOMT gene variant that is unique as it is the crossbreed.

Abstract

Stroke is a deadly disease in Indonesia. Meanwhile, marine organisms can contribute to providing active compounds for anti-stroke. The purpose of this review is to provide an overview of stroke sufferers in Indonesia and to identify potential active compounds from marine organisms that can treat or prevent stroke. The writing method was carried out by tracing the literature related to stroke and organisms that produce anti-stroke active compounds through Google Scholar. After collecting data from various literature, the next step was to process the data using simple statistics. Marine organisms that potentially contain anti-stroke active compounds are sea cucumbers (DHA, Docosahexaenoic acid), sea urchins (flavonoids), starfish (flavonoids), and jellyfish (amino acids), while marine organism biomarkers are biological responses of all living things in the sea to pollution and environmental pressures. This review is expected to be the beginning of the development of bioprospecting based on omics: metabarcoding and metagenomics, transcriptomics, proteomics, glycomics, lipidomics, and metabolomics.

Abstract

Hypertension is a major global health concern and a leading risk factor for cardiovascular mortality. Conventional treatment with ACE inhibitors like captopril is effective but often causes adverse effects including cough, dizziness, and renal impairment. This study evaluated the antihypertensive effects of rice bran in DOCA-salt-induced hypertensive rats. In vitro analysis revealed 45.58% soluble fiber and rich amino acid content, including 2.121 mg L-Arginine, a nitric oxide precursor promoting vasodilation. Male Wistar rats were divided into five groups: negative control, positive control, captopril treatment (5 mg/kg BW), and rice bran supplementation at 1% and 2% of 25 g feed. The 2% rice bran group significantly (p < 0.05) reduced renal iNOS expression by 88.32% compared to hypertensive controls, surpassing captopril's 22.96% reduction. Histopathological examination revealed notable renal protection with complete absence of fatty degeneration and minimal glomerular inflammation in the 2% rice bran group. These findings demonstrate potent antihypertensive activity through ACE inhibition, enhanced nitric oxide bioavailability, and mitigation of oxidative and inflammatory stress, establishing rice bran as a promising natural therapeutic alternative for hypertension management
