Abstract

Matoa (Pometia pinnata J.R.Forst & G. Forst) leaves contain polyphenols and flavonoids which areprospective for the development of the new antidiabetic agent. This research aimed to explore thepotency of matoa leaves in reducing blood glucose level and increasing plasma insulin concentrationin alloxan-induced rats. The experimental study was done in 6 treatment groups: the aquadest (normal),alloxan (Alx) 150 mg/kgBW (negative control), glibenclamide (Gli) 5 mg/kgBW (positive control),and matoa leaves extract (MLE) at the doses of 50, 100, and 200 mg/kgBW. The treatment wasadministered for 14 days orally post-induction of alloxan and fasting blood glucose (FBG) reached>200 mg/dL. Blood glucose levels were established by the GOD-PAP (Diasys) method while plasmainsulin was measured using Rat insulin ELISA kit. Hematoxyline-eosin (HE) staining on tissues wasperformed to observe the population of pancreatic beta cells. The results showed that the MLE extractat a dose of 200 mg/kgBW could decrease the FBG level to 135.25±21.14 mg/dL and increase theplasma insulin level up to 0.14%. Pancreas histopathology indicated that the number of damaged cellswere lower than negative control. In conclusion, our results affirm the promising potential of MLE asa candidate of the novel antidiabetic agent.

Abstract

Penelitian ekstrak etanol 50% daun matoa atau EEDM (Pometiapinnata J.R.Forst & G.Forst) dengan kandungan berupa flavonoidyang memiliki aktivitas antioksidan mampu menetralkan radikalbebas dengan meregenerasi sel ? pankreas dalam memproduksihormon insulin. Penurunan kadar gula darah disebabkan karenakelebihan gula disimpan dalam bentuk glikogen dengan bantuanhormon insulin. Penelitian ini bertujuan untuk menetapkan pengaruhekstrak etanol 50% daun matoa atau EEDM (Pometia pinnataJ.R.Forst & G.Forst) terhadap kadar glikogen hati pada tikuspercobaan yang diinduksi aloksan 150 mg/kgBB. Penelitianeksperimental dilakukan dengan RAL (Rancangan Acak Lengkap)terhadap 6 kelompok perlakuan yang diberi perlakuan denganakuades tanpa induksi, akuades, glibenklamid 5 mg/kgBB, dan tigakelompok EEDM dengan dosis 50, 100, dan 200 mg/kgBB EEDMselama 14 hari. Kadar glikogen ditetapkan dengan metode antronmenggunakan hati tikus yang telah dikeringkan. Hasil dari penelitianmenunjukkan bahwa EEDM dosis 50 dan 100 mg/kgBB mampumeningkatkan kadar glikogen hati yang tidak berbeda signifikan(sama) dengan kelompok tikus kontrol positif yang diberikanglibenklamid dosis 5 mg/kgBB.
