Abstract

AbstractIn plant tissue culture, the culture vessels are usuallycovered tightly with screw caps, aluminium foils, parafilm,or plastic wrap. This condition restricts the exchange ofgases in culture vessels and will affect negatively thegrowth of explants. The use of ventilated closure improvesthe air quality in culture vessels. Microboxes provided withdifferent types of filter (yellow filter with Kv value13.09 Gas Exchange (GE)/day, green filter with Kv value81.35 GE/day and without filter) on their closure wereexamined as culture vessels for growing rubber explants atmultiplication step. The purpose of this research was toobserve the plant condition in different types of microboxcorresponding to the morphology, stomata and chlorophyllcontent of the shoots. The results showed no significantdifference of shoot height on each microbox. The use ofventilated closure increased significantly new leafformation and decreased leaf fall. Normal size and color ofleaves were found on shoots grown in microbox with greenfilter. Chlorophyll analysis revealed no significantdifferences on three types of microbox, however visualobservation showed that leaves were greener on microboxwith green filter. The stomata condition of shoots onmicrobox with green filter were similar with those ofmother plants in green house, while different condition ofstomata were found on shoots grown in microbox withyellow filter or without filter. In normal environment suchas at the field and green house, most of stomata wereclosed, in microbox provided with filter on the closure,most of stomata were half open, while on microbox withoutfilter most of stomata were wide open.bstrakDalam kultur jaringan tanaman, tabung/botol kulturditutup rapat dengan penutup yang dilengkapi ulir,aluminium foil, parafilm atau plastik wrap. Kondisitersebut menghambat pertukaran udara dalam tabung kultursehingga sering memberikan pengaruh negatif terhadappertumbuhan eksplan. Penggunaan penutup berventilasidapat meningkatkan kualitas udara dalam lingkungantabung/botol kultur. Oleh karena itu microbox denganpenutup berfilter diuji sebagai wadah untuk menumbuhkaneksplan karet pada tahap multiplikasi, yaitu microboxberfilter kuning dengan nilai Kv sebesar 13,09 (GasExchange (GE)/hari dan berfilter hijau dengan nilai Kvsebesar 81,35 GE/hari, sedangkan sebagai kontrol adalahmicrobox tanpa filter (tertutup rapat). Penelitian bertujuanmengamati kondisi tunas di dalam microbox berfilter,meliputi morfologi, stomata dan kandungan klorofil. Hasilpenelitian menunjukkan bahwa tinggi tunas tidak berbedanyata pada masing-masing microbox.

Abstract

Some Asteraceae plants have phytochemicals that are commonly used to treat some illness. However, research on the use of Asteraceae plants as tyrosinase inhibitor agents is still rare. Therefore, this study aims to select the most active fraction of Asteraceae species as tyrosinase inhibitors and suspect active compounds that play a role in it. About 12 species from Asteraceae are extracted using water. The resulting filtrate is partially fractionated using chloroform to obtain water extracts, water fractions, and chloroform fractions. Each extract and fraction of each plant determined the activity of its tyrosinase inhibitor using a microplate reader (ELISA) with L-DOPA as the substrate. Thitonia diversipholia water fraction provided the best activity of all the samples tested with the smallest IC50. The active compounds contained are analyzed using LC-MS / MS.  Compounds that act as tyrosinase inhibitors are alkaloid group that dominate the plant, namely trigonelline.

Abstract

The leaves of Annona muricata (sirsak), Gynura procumbens (sambung nyawa), and Typhonium flagelliforme (keladi tikus) have been used as traditional medicines in Indonesia. This study aims to determine the antioxidant capacity and putatively identified phenolics from the leaves of three medicinal plants forementioned above. We used the DPPH (2,2-diphenyl-1-picrylhydrazyl) method for measuring radical scavenging (antioxidant assay) while the phenolics profiling was determined using UHPLC-Q-Orbitrap HRMS. The results showed that the percentage of radical scavenging activity of G. procumbens leaves extract in ethanol was higher than the other two plants. Phenolics profiling of the three medicinal plants was identified with 38 compounds belonging to flavones and flavanols hydroxycinnamic acid, and several other groups. The number of metabolites identified putatively was 12, 31, and 19 metabolites in the extracts of A. muricata, G. procumbens, and T. flagelliforme, respectively. The results confirmed the correlation between the phenolics presence and the antioxidant capacity of three plants used in this study.

Abstract

Chitosan is a natural polymer that can be used as wound dressing material; however, it has rigid and brittle properties. A combination of chitosan and polyvinyl alcohol (PVA) is expected to allow improvement of chitosan’s mechanical properties. Green grass jelly leaf (Cyclea barbarta M.) and moringa leaf (Moringa oleifera L.) have antibacterial compounds that can be added to the chitosan-PVA composite membrane. The purpose of the research was to develop and characterize the chitosan-PVA composite membrane with the addition of green grass jelly leaf and moringa leaf extracts to enhance the antibacterial activity of the membranes that have potential as a wound dressing. Both extracts with various composition volumes (75:25, 50:50, and 25:75) were tested for antibacterial activities against S. aureus and E. coli. Chitosan-PVA composite membrane with the volume ratios of 5:5, 6:4, and 7:3 was added with extract with the highest antibacterial activity. The composites were characterized for density, water vapor permeability, tensile strength, elongation, Fourier Transform Infrared spectroscopy, and Scanning Electron Microscope. The most significant inhibition zone was shown by an extract ratio of 50:50 against S. aureus and E. coli, 13.00±1.17 mm and 7.00±0.17 mm, respectively. Composite membrane with the addition of extract had a larger inhibition zone against S. aureus (9.75±0.75 mm) and E. coli (7.50±0.65 mm) than without extract. Chitosan-PVA(5:5)+extract membrane showed excellent density and water vapor permeability compared to other membrane ratio compositions. Mechanically, the addition of extract decreased the tensile strength and elongation of the membranes; however, it still complied with the medical material standard criteria. The characterization for functional groups showed that chitosan-PVA+extract generated the N-H group peak with two wavenumbers expressed as overlapping amides with amines and protonated amines. The SEM analysis showed that the addition of extract was not distributed homogeneously on the membrane surface.

Abstract

Pomegranate has valuable nutritional content and contains various bioactive compounds, one found in the fruit's peel. The utilization of these bioactive compounds could be used as herbal medicines and supplements, such as antioxidants. This study aimed to determine the antioxidant capacity, phytochemical profile, and pomegranate peel extract grouping using different extracting solvents. The three extracting solvents used were water, 70% ethanol, and ethanol p.a. Antioxidant capacity of the three extracts was measured using the DPPH and CUPRAC methods. We also determined the total phenolic and flavonoid levels and the TLC fingerprint analysis and FTIR spectrum of the pomegranate peel extracts. The 70% ethanol extract owned the largest antioxidant capacity than the other two extracts with a value of 358.67 and 2981.59 µmol trolox/g dried sample using the DPPH and CUPRAC methods, respectively. The three pomegranate peel extracts' total phenolic and flavonoid levels ranged from 287.26–1068.81 mg GAE/g dried sample and 0.24-0.75 mg QE/g dried sample. TLC fingerprint analysis of pomegranate peel extract yielded 2, 6, and 6 bands for water extract, 70% ethanol, and p.a ethanol, respectively. The three extracts can be grouped based on FTIR spectrum data using principal component analysis using three principal components with a total variance of 93%. The results obtained show that using different extracting solvents provides different antioxidant capacities and phytochemical profiles.

Abstract

In Indonesia, Gynura procumbens (Lour.) Merr., known as Longevity Spinach or Sambung Nyawa, is commonly grown in tropical and subtropical Asian countries. Many biological activities of G. procumbens have been reported. As we know, the composition and concentration of metabolites, as well as plant parts will significantly affect the biological activities. In this work, UHPLC-Q-Orbitrap-HRMS was used for the putative identification of metabolites present in 70% ethanol extract of G. procumbens leaves and stem extract. Also, we performed clustering of G. procumbens leaves and stem extracts using principal component analysis (PCA) with the peak area of the identified metabolites as the variable. Thirty-one metabolites were identified, and the number of identified peaks in the leaves is higher than in the stem. Those identified metabolites are phenolics, fatty acids, oxo monocarboxylic acids, porphyrins, and chlorophyll fragments. The PCA results showed that the leaves and stem extracts could be grouped, indicating that the composition and concentration of detected compounds differed.

Abstract

One of the main antigen that can be used for serological testing is the nucleocapsid (N) which is the most abundant viral-derived protein in SARS-CoV-2 where this virus can cause COVID19 disease. The aim of this study was to develop the SARS-CoV-2 N recombinant protein using Escherichia coli expression system. A total of 1,089 nucleotides encoding 362 amino acids of SARS-CoV-2 N was cloned to pET-14b vector. The plasmid then expressed in E. coli BL21 (DE3) and induced with 1.0 mM IPTG (Isopropyl-β-d-1-thiogalactopyranoside). The cell was harvested using denaturation lysis buffer due to inclusion body formation of SARS-CoV-2 N protein. Dialysis processed and concentrated using PEG-6000 resulted 0.992 mg/ml protein yield. Analysis of SARS-CoV-2 N recombinant protein using SDS-PAGE technique showed approximately 37.0 kDa specific band target protein. Application of this SARS-CoV-2 N recombinant protein to vaccinated and non-vaccinated antibody serum samples using ELISA technique indicated the significant result of optical density mean at 0.603 and 0.135, respectively. This study revealed that the production of SARS-COV-2 N recombinant protein could be carried out in E. coli expression system under denatured conditions, therefore the methods are more effective in producing the protein as a basic material in immuno-diagnostic assay.

Abstract

Silk fiber is an organic waste that can pollute the environment due to its solubility in processing wastewater. The extraction from wastewater was carried out to reduce environmental pollution and produce natural bioactive. Therefore, this research aims to produce an extraction method that maximizes the protein yield of Attacus atlas (A. atlas) and Samia cynthia ricini (S. ricini) sericin and analyze the characteristics. The method consists of two stages, the optimization of sericin protein extraction with Response Surface Methodology (RSM) and its characterization. The optimization resulted in the optimum extraction of A. atlas and S. ricini sericin at a concentration of 0.08 and 0.03 N NaOH, temperature of 130.52 °C and 113.20 °C, time of 71.71 and 33.78 minutes with a yield of 17.39±1.24% and 20.24±2.30%. The sericin protein had a molecular weight of 8.99 and 7.08 kDa in A. atlas and S. ricini. The extraction produces glycine, alanine, and tyrosin for A. atlas and glutamic acid, glycine, and alanine for S. ricini. Therefore, the sericin extraction formulation did not change the secondary structure protein, as evidenced by the FTIR results.
