      Abstract
      Keberagaman wilayah geografis dapat mempengaruhi produktivitas tanaman lokal. Penelitian ini bertujuan mengidentifikasi pengaruh lokasi tumbuh dan jenis pelarut pada ekstraksi kulit kayu manis (Cinnamomum burmannii) asal Jambi, Padang Aro dan Bogor terhadap total flavonoid metode kolorimetri dengan pereaksi AlCl3 dan aktivitas antioksidannya melalui uji FRAP. Ekstrak hasil maserasi etanol 70% dari kayu manis yang tumbuh di Padang Aro menunjukkan hasil tertinggi dibanding sampel lainnya pada pengukuran total flavonoid dan aktivitas antioksidan yaitu sebesar 22,09 mgQE/g dan 4408,55 µmolTE/g. Meskipun demikian, simplisia asal Padang Aro menghasilkan rendemen paling sedikit dibandingkan sampel lainnya untuk semua jenis pelarut: 14,74% pada ekstrak etanol dan 6,89% pada ekstrak air. Berdasarkan hasil uji korelasi Pearson, jumlah flavonoid berkorelasi tidak signifikan terhadap aktivitas antioksidan metode FRAP (R= 0,79; CI = - 0,05–0,97).
       
      Geographic diversity can influence local crop productivity. This research aims to identify the effect of growth location and type of solvent used in the extraction of cinnamon (Cinnamomum burmannii) bark grew in Jambi, Padang Aro and Bogor on total flavonoids examinated by colorimetric method with AlCl3 reagent and their FRAP antioxidant activity. Etanol 70% extract from maseration of cinnamon bark growth in Padang Aro showed the highest results compared to other samples in total flavonoids and antioxidant activity measurement, 22,01 mgQE/g and 4408,55 µmolTE/g. Otherwise, simplicia from Padang Aro produced the lowest yield compared to other samples for all types of solvents: 14,73% in ethanol extract and 6,89% in water extract. According to the result of Pearson correlation test, the amount of flavonoids are not significantly correlated with FRAP method antioxidant activity (R= 0,79; CI = - 0,05—0,97).
