Abstract

Kratom (Mitragyna speciosa) is a medicinal plant native to Southeast Asia that contains a wide range of secondary metabolites. The characteristics of medicinal plant extracts are strongly influenced by the type of solvent used during the extraction process, particularly with respect to phenolic compounds that play a key role in antioxidant activity. This study aimed to evaluate the antioxidant activity and total phenolic content of Mitragyna speciosa leaf extracts obtained using solvents with different degrees of polarity. Kratom leaves were extracted with water using the decoction method, as well as with 70% and 90% ethanol using the maceration method. Total phenolic content was determined by Spectrophotometer UV–Vis employing the Folin–Ciocalteu reagent with gallic acid as the standard, while antioxidant activity was assessed based on IC₅₀ values using the DPPH assay. The results showed that the total phenolic content of the water, 70% ethanol, and 90% ethanol extracts was 81.27 ± 0.13, 93.85 ± 0.07, and 99.21 ± 0.07 mg GAE/g extract, respectively. Antioxidant activity analysis revealed IC₅₀ values of 64.71 µg/mL for the water extract (strong antioxidant), 35.52 µg/mL for the 70% ethanol extract (very strong antioxidant), and 35.12 µg/mL for the 90% ethanol extract (very strong antioxidant). Based on these findings, the 90% ethanol extract exhibited the highest total phenolic content and the most potent antioxidant activity, indicating its potential for development as a natural antioxidant source derived from kratom leaves.

Abstract

Diabetes mellitus (DM) memiliki hubungan yang erat dengan perubahan pola makan dan gaya hidup yang tidak sehat. Jumlah penderita diabetes di Indonesia terus meningkat. Minat masyarakat dalam mengonsumsi tanaman obat semakin berkembang karena pasien lebih memilih produk alami yang dianggap lebih aman. Penelitian tentang tanaman obat sebagai agen antidiabetes juga menunjukkan tren yang meningkat. Studi ini bertujuan untuk memetakan penelitian yang menggunakan tanaman obat terkait diabetes di Indonesia. Data subjek penelitian diperoleh dari Scopus, dan perangkat lunak statistik RStudio dengan paket bibliometric digunakan untuk menganalisis dan memvisualisasikan data. Hasil analisis menunjukkan bahwa pertumbuhan publikasi di bidang ini mencapai 36,25% per tahun. Jumlah penulis bersama per dokumen adalah 4,93 dengan tingkat kolaborasi internasional sebesar 15,12%. Sebanyak 1.548 artikel dengan 4.877 penulis diterbitkan di 429 jurnal dan prosiding terpilih. Elya B (n = 35), Universitas Airlangga (n = 435), dan IOP Conference Series: Earth and Environmental Science (n = 92) merupakan penulis, afiliasi, dan penerbit paling produktif. Dengan jumlah sitasi per artikel sebesar 7,78 menunjukkan bahwa penelitian dari Indonesia berkontribusi pada penelitian lain. Penulis artikel di Indonesia sebagian besar (89,73%) berkolaborasi dengan peneliti sesama di Indonesia, sementara sisanya (10,27%) berkolaborasi dengan peneliti di luar negeri seperti Jepang, Malaysia, Thailand, China, dan Korea. Dapat disimpulkan bahwa kuantitas dan kualitas penelitian tentang tanaman obat untuk DM di Indonesia semakin meningkat dan berkontribusi pada penelitian lebih lanjut untuk pengelolaan diabetes. Kata Kunci: Bibliometric, Diabetes Mellitus, Tumbuhan Obat, Scopus, Rstudio Diabetes mellitus (DM) strongly associated with changes in unhealthy diet and lifestyles. The number of diabetic patients in Indonesia continues to increase. Public interest in consuming medicinal plants was developing because patients prefer on natural products and are considered safer. Research on medicinal plants as antidiabetic agents also shows an increasing trend. This study aims to map research using medicinal plants related to diabetes in Indonesia. Data on research subjects were retrieved from Scopus and the bibliometric package in RStudio statistical software was used to analyze and visualize the data. The results of the analysis showed that the growth of publications in this field was 36.25% per year. The number of co-authors per document was 4.93 with an international co-authorship rate of 15.12%. A total of 1548 articles with 4877 authors were published in 429 selected journals and proceedings. Elya B (n = 35), Universitas Airlangga (n = 435), the IOP Conference Series: Earth and Environmental Science (n = 92) was the most productive author, affiliation, and publisher. With the number of citations per article of 7.78, it shows that this research from Indonesia contributes to another research. The authors of the articles in Indonesia mostly (89.73%) collaborated with fellow researchers in Indonesia, while the rest (10.27%) collaborated with researchers abroad such as Japan, Malaysia, Thailand, China, and Korea. It can be concluded that the quantity and quality of research on medicinal plants for DM in Indonesia is increasing and contributing to further research for diabetes management.
