Kalanchoe pinnata (Lmk) Pers (KP) has an immunosuppressive effect on delayed-type hypersensitivity test. Based on it, this research aimed to determine the repairing effects of aqueous extract of KP on lupus nephritis mice and identified its active compound. The KP extract profile was determined using UPLC-QTOF-MS/MS instrument. We examined six mice groups consisting of three curative treatment groups, one standard group receiving prednisone, one preventive group receiving KP extract, and one healthy (healthy and untreated) group. At the end of the experiment, we measured the proteinuria and renal histology parameters. To recognize the active compound in the KP profile, we performed in silico assays for the flavonoid compounds to bind to the glucocorticoid receptor. We played in silico tests for the flavonoid compounds to identify the active compound in the KP profile. We found the repairing effect of KP was detected in the kidney, demonstrated by its low proteinuria level and its better tissue structure. In the curative group, the urine protein level and its glomerular inflammation decreased. In the preventive group, the aqueous extract of KP could prevent lupus nephritis manifestations in the kidney. Bryophyllin A is the most active compound of the KP. However, further research is needed to understand the mechanism involved. We conclude, the aqueous extract, especially its bryophyllin A, have beneficial effects in repairing the function and tissue structure of lupus manifestations in mice kidney.
Mitragyna is a genus belonging to the Rubiaceae family and is a plant endemic to Asia and Africa. Traditionally, the plants of this genus were used by local people to treat some diseases from generation to generation. Mitragyna speciosa (Korth.) Havil. is a controversial plant from this genus, known under the trading name “kratom”, and contains more than 40 different types of alkaloids. Mitragynine and 7-hydroxymitragynine have agonist morphine-like effects on opioid receptors. Globally, Mitragyna plants have high economic value. However, regulations regarding the circulation and use of these commodities vary in several countries around the world. This review article aims to comprehensively examine Mitragyna plants (mainly M. speciosa) as potential pharmacological agents by looking at various aspects of the plants. A literature search was performed and information collected using electronic databases including Scopus, ScienceDirect, PubMed, directory open access journal (DOAJ), and Google Scholar in early 2020 to mid-2021. This narrative review highlights some aspects of this genus, including historical background and botanical origins, habitat, cultivation, its use in traditional medicine, phytochemistry, pharmacology and toxicity, abuse and addiction, legal issues, and the potential of Mitragyna species as pharmaceutical products.
Background: Bitter gourd has various metabolites, such as momordicosides, polypeptide-P, v-insulin, charantin, and vicine that have antidiabetic effect. It has synergistically effect while combined with oral diabetic drugs, such as metformin as glucose lowering agent. The aim of this study is to investigate the interaction of bitter gourd fruit juice and metformin as glucose lowering agent in mice.Materials and Methods: Alloxan-induced diabetic mice were treated with bitter gourd fruit juice, metformin, and the combination of those two for 21 days. Glucose level was checked on first and last day of treatment.Results: Furthermore, blood glucose levels measurement showed no significant difference between groups compared with negative control, which was p>0.05. The stomach of groups that treated with metformin and bitter gourd fruit juice histopathologically showed no significant differences.Conclusion: The use of bitter gourd once daily together with metformin is a better choice, while twice daily might induce hypoglycemia and mice death. There is no interaction between them on lowering blood glucose.Keywords: metformin, Momordica charantia, diabetes mellitus
Averrhoa bilimbi Linn is a plant that is used by the local community as an itchy and acne remedy. Secondary metabolite content of ethanol extract of Starfruit leaves (Averrhoa bilimbi Linn) can inhibit the growth of acne bacteria. The purpose of this study was to determine the best concentration in the manufacture of anti-acne gel formulations of ethanol extract of Starfruit leaves (Averrhoa bilimbi Linn) using HPMC base. Extract concentrations were made of 5%, 7.5%, and 10%. After antibacterial tests, the extract concentration used was 7.5% with a inhibition zone of 11.17 mm P.acnes bacteria and 11.30 mm S.aureus bacteria. Anti-acne gel ethanol extract of starfruit leaves (Averrhoa bilimbi Linn) made 3 replication formulas with extract levels FR1 (7.5%), FR2 (7.5%) and FR3 (7.5%). The results showed that the color of the dark green preparation, distinctive smell, thick, no syneresis, ph 4.7-6.2, scatter power 4.6-5.2 cm, clinginess 6-22 seconds and viscosity of 11-20 Pa.s. Antibacterial activity tests on P.acnes showed a inhibition zone of 10.1-10.73 mm and S.aureus showed a inhibition zone of 10.35-10.93 mm. So, it was concluded that the formulation of anti-acne gel was able to inhibit the growth of P.acnes and S.aureus bacteria and meet physical characteristics.
Objective: The aim of this research was to measure the effects of the ethyl acetate fraction of Kalanchoe pinnata (Lmk) Pers (EF-KP) on lupus arthritis mice. Methods:The research was performed by testing of CD123 + interferon-α (IFN-α + ) dendritic cells and CD68 + interleukin 6 (IL-6 + ) macrophages as the main biomarkers using flow cytometry method, and then, the outcomes were directly observed in the joint's tissue structure. The results of the research were analyzed using statistics. Results IL-6+ macrophages but not significantly. Finally, the outcome to the grade of joint damage was scored using Pritzker method. The treated groups have one grade lower, and the joint spaces were narrower than the untreated group. Conclusion:The results show the ability of the active compounds in EF-KP, which are comparable to 0.042 mg/kg of quercetin, to inhibit the progress of lupus arthritis pathogenesis in mice. It might reveals the effectiveness of the EF-KP in human with lupus arthritis. However, the further clinical research is necessary.
