Abstract

BACKGROUND: Peronema canescens Jack is traditionally employed in the treatment of inflammation, malaria, and immune-related disorders. Despite its traditional use, scientific evidence on its immunomodulatory effects, interleukin (IL)-6 modulation, hematological impact, as well as its related acute toxicity data remains limited. Therefore, this study was conducted to investigate the immunostimulatory potential of P. canescens leaf extract through in vitro and in vivo assessments and evaluate its acute toxicity profile.METHODS: The in vitro immunomodulatory activity of P. canescens ethanolic extract, n-hexane fraction (NHF), ethyl acetate fraction (EAF), and water fraction (WF) were assessed by measuring IL-6 inhibition in lipopolysaccharide-stimulated RAW 264.7 macrophages. For in vivo analysis, Balb/C mice were divided into six groups: a normal control (Na-CMC), a positive control (50 mg/kg BW/day Stimuno Phyllanthus niruri extract), a negative control (80 mg/kg BW/day cyclophosphamide as immunosuppressant), and 3 treatment groups receiving P. canescens extract at doses of 100, 200, and 400 mg/kg BW/day. Hematological parameters, including white blood cell (WBC) counts, lymphocyte percentages, and neutrophil percentages, were analyzed. Acute toxicity studies were performed by administering P. canescens extract at doses of 300, 2000, and 5000 mg/kg BW over observation period.RESULTS: EAF exhibited the most pronounced IL-6 inhibition in vitro. In vivo, the administration of P. canescens extract at 200 and 400 mg/kg BW significantly elevated WBC and lymphocyte levels while concurrently reducing neutrophil counts. No mortality or neurotoxic manifestations were observed, confirming the P. canescens extract’s safety profile up to 5000 mg/kg BW.CONCLUSION: P. canescens leaf extract, particularly EAF, demonstrates robust immunomodulatory activity with a favorable safety margin. These findings underscore its potential therapeutic application in immune modulation.KEYWORDS: Peronema canescens Jack, immunomodulatory, IL-6 inhibition, acute toxicity, hematology, cytokines

Abstract

The flowers of Abelmoschus manihot have been broadly studied in China for their phytochemical content and biological activities; however, the leaves have been explored only to a limited extent. In Manado, Sulawesi, Indonesia, the leaves of this plant are the most important ingredient in tinutuan porridge. The total phenols (TPC) and total flavonoids (TFC) in the leaves collected in Bogor, Manado, Tomohon, and Kotamobagu have been previously reported. This study aimed to provide data on the proximate and phytochemical composition (TPC, TFC, and quercetin levels) of the ethanol extract of A. manihot leaves collected from Tinoor Dua Village, North Tomohon, North Sulawesi, Indonesia. Extraction was carried out at room temperature using 70% ethanol. The phytochemical screening test was conducted according to a standard procedure for plant extracts. The proximate composition of the extract was analyzed in accordance with SNI 01-2891-1992. The TPC and TFC were determined by following the procedures outlined in SNI 01-2891-1992. Additionally, the TPC and TFC were also determined in accordance with SNI 01-2891-1992, and the procedures outlined in the Indonesian Herbal Pharmacopoeia were followed. Quercetin levels were analyzed using HPLC. Proximate analysis revealed 35.60% of total ash, 28.56% of carbohydrate, 18.31% of water, 11.01% of protein, and 6.53% of fat, whereas the TPC was 1350 mg GAE/100 g extract, the TFC was 2670 mg QE/100 g extract, and quercetin in the extract was 373.7 ± 0.18 mg/L. These findings will support further exploration for the development of A. manihot leaves as a nutritional food or nutraceutical supplement.
