Flavonoid Level Determination in Jamu Pegel Linu in Magelang Regency Using Uv-Visible Spectrophotometry
Jamu is made from the toga plant, which is still used medicinally in Indonesia. Rutin, a type of flavonoid component, is frequently present in herbal medicine pegel linu. Rutin serves as an antioxidant and anti-inflammatory by neutralizing free radicals, which helps to prevent tissue damage and relieve soreness. This research's objective was to evaluate the amounts of flavonoids in samples using UV-Visible spectrophotometry, employing three samples of herbal medicine (A, B and C) as well as the standard solution, reagents AlCl3 and sodium acetate. In this investigation, the protocol utilized to determine the maximum wavelength was 400–800 nm, and the result was 413.5 nm. The linear regression equation is y = 0.0471x + 0.0624 with a correlation coefficient of R2 of 0.9934 and a LOD value of 3.9694 mg / L and a LOQ value of 13.231 mg / L. The determination of total flavonoid levels considered as rutin uses concentrations of 10, 12.14, 16 and 18 ppm with operating time of 30 minutes. The findings of rutin content analysis for samples A, B, and C were 1.6683%, 2.8763%, and 3.0923%, respectively
Genipin as a Cross-linker in a Ciprofloxacin Delivery System Containing a Bovine Hydroxyapatite-Collagen Composite for Bone Infections
The purpose of this research was to design an implant for a ciprofloxacin-based drug delivery system by combining bovine hydroxyapatite and collagen with genipin as the crosslinking agent. The production of ciprofloxacin implants using bovine hydroxyapatite:collagen blend (70:30). In addition, this synthetic preparation was made using three various concentrations of genipin (0.6, 0.8, and 1.0%). The pellets were created by compressing the implants. The tablets are cylindrical with a diameter of 4.0 mm and a weight of 100.0 mg. Ciprofloxacin cultures were characterized for swelling rate, porosity, density, compressive strength, morphology (SEM), dose, and drug release in vitro. The addition of genipin as a crosslinking agent may maintain ciprofloxacin release consistent with in vitro therapeutic levels of ciprofloxacin. These results are supported by compressive strength data, where the addition of genipin concentrations induces higher implant stiffness and scanning electron microscopy photomicrographs reveal small pore sizes and BHA adhere to collagen fibers so that ciprofloxacin is completely dispersed in the implant after cross-linking with genipin. As a drug delivery system for osteomyelitis, it can be concluded that the use of genipin as a cross-linking agent can sustain ciprofloxacin release commensurate with in vitro therapeutic levels of ciprofloxacin for 30 days
Preliminary Phytochemical Screening and Quantitative Analysis of Methanol Leaf Extract of Erlangea tomentosa (Oliv. & Hiern) S.Moore (Asteraceae)
Various medications are being developed using natural products, particularly those resulting from medicinal plants. So, the screening and quantity analysis of phytochemicals in the methanol leaf extract of Erlangea tomentosa was looked at to find out what chemicals in the plant were responsible for its biological activity. Ten different phytochemicals, such as alkaloids, glycosides, cardiac glycosides, flavonoids, saponins, coumarins, steroids, terpenoids, phenols, and tannins, were found by the analysis. Glycosides and cardiac glycosides were below the limits, and neither phlobatannins nor anthraquinones were found. Quantitative phytochemical analysis showed that there were 3.38g of alkaloids, 2.19g of tannins, 1.81g of flavonoids, and 0.31g of saponins. The concentrations of standard solutions per 100g of crude sample were used to estimate all the results of the tests
In-Silico Screening of Mitragynine Derivates from the Genus Mitragyna Korth Targeting the Main Protease of the SARS-COV-2
Coronavirus Diseases 2019, caused by SARS-CoV-2, has been a significant threat to global public health. Unfortunately, effective COVID-19 vaccines and clinically-proven anti-SARS-CoV-2 drugs remain unavailable. This study was carried out aiming to predict the potential effect of mitragynine derivates from the Genus Mitragyna Korth as an inhibitor of Mpro, the main protease of the SARS-CoV-2, by in silico molecular docking study. The crystal structure of the main protease of SARS-CoV-2 as an active site target was obtained from the PDB database (rcsb.org) with PDB ID: 5R84 and 6LU7 with the native ligand of Z31792168 and N3, respectively. The analysis of in silico molecular docking was conducted using Autodock 4.2.6 (100 docking runs). The central grid was placed on HIS41 and CYS145 with a grid box comprised of 40x30x34 (for protein 5R84) and 36x62x40 (for protein 6LU7) points spaced by 0.375 Å was centered on the active site of X=9,812; Y=-0,257; Z=20,849 and X=-9.732; Y=11.403; X=68,483 (XYZ-coordinates), respectively. Our research indicated that mitrjavine and ajmalicine exhibit greater potential inhibition of the active site on the Mpro of SARS-CoV-2, even stronger than native ligands. We believed that these compounds are promising candidates to be examined in further COVID-19 drug discovery studies

The data was analyzed using paired t-test. State the results of the values obtained the combination of dark chocolate and herbs showed a significant reduction in pain before and after treatment (p<0.05). Based on these results, it was concluded that the combination of dark chocolate with herbs could be one of the therapies for dysmenorrhea
Synergistic Effect of Pericarp of Mangosteen and Propolis from Stingless Bee Extracts on Nitric Oxide Scavenging Activity
The aim of this research is to study the synergistic effect on the nitric oxide scavenging activity of mangosteen pericarp and the stingless bee (Tetragonula laviceps) propolis extracts and their phytochemical constituents. The propolis and mangosteen pericarp were extracted by reflux method with ethanol. TPC and TFC of propolis extract were 123.73±2.80 mg GAE/g extract and 70.65±11.21 mg QE/g extract, respectively, and mangosteen pericarp extract was 387.93±15.10 mg GAE/g extract and 87.00±5.06 mg QE/g extract, respectively. The ESI-LC-MS data displayed that both extracts have a variety of phytochemical constituents, such as xanthones, flavonoids, and miscellaneous. The synergistic effect of Nitric oxide scavenging activities of propolis and mangosteen pericarp extracts showed higher activity than individual extracts with various concentrations. Thus, the synergistic effect of propolis and mangosteen pericarp extracts may be an alternative source of inflammatory drug development in the future
Test of Antidiabetic Effect of Taro Leaf Extract (Colocasia esculenta L.) on Zebrafish (Danio rerio)
Diabetes mellitus (DM) is a common metabolic disorder defined as chronic hyperglycemia. In addition to the symptoms associated with hyperglycemia itself such as thirst, polyuria and weight loss, it can also cause acute hyperglycemia emergencies that are potentially life threatening. One of the traditional plants that has potential as an antidiabetic drug is the taro plant (Colocasia esculenta L) because it contains chemical compounds such as alkaloids, flavonoids, saponins, tannins and polyphenols which are known to have antidiabetic effects. This study aims to determine the effectiveness and what dose of Taro Leaf Extract gives the best effect of reducing blood glucose levels in zebrafish. This study used zebrafish (Danio rerio) induced with alloxan and glucose to raise blood glucose levels. The 20 test animals used were divided into 6 groups, namely group 1 without treatment (normal), group 2 control (-) alloxan induction 0.1% + glucose 1%, group 3 control (+) metformin, group 4 taro leaf extract 200 mg, group 5 taro leaf extract 300 mg, group 6 taro leaf extract 400 mg. Then glucose levels were measured using a glucometer. Data analysis was carried out statistical tests. The results showed that a dose of 400 mg/2L had the ability to reduce blood glucose levels that were not significantly different from normal zebrafish glucose levels
