Although gestational diabetes mellitus (GDM) is mainly characterized by insulin resistance, severe hyperglycemia may also result from impaired pancreatic function. This study evaluates the therapeutic potential of pandan (Pandanus amaryllifolius) root and teak (Tectona grandis) leaf extracts in managing streptozotocin (STZ)-induced maternal hyperglycemia in pregnant rats, compared to metformin. Methods: Pregnant rats were administered STZ (60 mg\/kg) on gestation day 5. Treatments with metformin (300 mg\/kg), pandan extract (low, medium, high doses), and teak extract (low, medium, high doses) were given from gestation day 7 to 21. The key parameters included the maternal blood glucose, insulin levels, pancreatic morphology, fetal and placental outcomes, and gas chromatography\/mass spectrometry (GC\/MS) phytochemical profiling. GC\/MS analysis identified 2,3-butanediol and propanoic acid derivatives as major compounds in pandan, while teak contained catavic acid and methyl copalate. The high-dose pandan extract significantly reduced the maternal blood glucose (p &lt; 0.05), improved the insulin levels and pancreatic mass index, and increased the number of live fetuses, with effects comparable to metformin. The teak extract showed milder improvements. The pandan extract demonstrated dose-dependent antidiabetic potential in this STZ-induced model. Future studies should evaluate these effects in insulin-resistance-based GDM models.<\/jats:p>","DOI":"10.3390\/ijms26125506","type":"journal-article","created":{"date-parts":[[2025,6,9]],"date-time":"2025-06-09T06:46:01Z","timestamp":1749451561000},"page":"5506","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Potential of Pandan Root and Teak Leaf Extracts in Managing Maternal Hyperglycemia During Pregnancy: Comparative Efficacy and Mechanistic Insights"],"prefix":"10.3390","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7742-8169","authenticated-orcid":false,"given":"Sasitorn","family":"Kerdsuknirund","sequence":"first","affiliation":[{"name":"School of Preclinical Sciences, Institute of Science, Suranaree University of Technology, Nakhon Ratchasima 30000, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Panida","family":"Khunkaewla","sequence":"additional","affiliation":[{"name":"Biochemistry-Electrochemistry Research Unit, School of Chemistry, Institute of Science, Suranaree University of Technology, Nakhon Ratchasima 30000, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pakanit","family":"Kupittayanant","sequence":"additional","affiliation":[{"name":"School of Animal Technology and Innovation, Institute of Agricultural Technology, Suranaree University of Technology, Nakhon Ratchasima 30000, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Suthida","family":"Chanlun","sequence":"additional","affiliation":[{"name":"Department of Pathobiology, Faculty of Veterinary Medicine, Khon Kaen University, Khon Kaen 40000, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pattama","family":"Tongdee","sequence":"additional","affiliation":[{"name":"School of Obstetrics and Gynecology, Institute of Medicine, Suranaree University of Technology, Nakhon Ratchasima 30000, Thailand"},{"name":"Suranaree University of Technology Hospital, Nakhon Ratchasima 30000, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Porntip","family":"Nimkuntod","sequence":"additional","affiliation":[{"name":"Suranaree University of Technology Hospital, Nakhon Ratchasima 30000, Thailand"},{"name":"School of Internal Medicine, Institute of Medicine, Suranaree University of Technology, Nakhon Ratchasima 30000, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sajeera","family":"Kupittayanant","sequence":"additional","affiliation":[{"name":"School of Preclinical Sciences, Institute of Science, Suranaree University of Technology, Nakhon Ratchasima 30000, Thailand"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,6,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Lende, M., and Rijhsinghani, A.
