Abstract
Rimpang jahe merah (Zingiber officinale Roscoe var. rubrum) salah satu tanaman yang memiliki banyak kegunaan, selain menjadi salah satu tanaman yang digunakan untuk memasak, tanaman ini juga dimanfaatkan secara tradisional dalam pengobatan dan menjadi salah satu jenis bahan baku dalam pembuatan jamu di Indonesia. Menurut beberapa penelitian, rimpang jahe merah memiliki kandungan senyawa flavonoid dan polifenol, salah satunya senyawa gingerol. Maka dari itu tujuan dari penelitian ini adalah mengetahui kadar total senyawa flavonoid dan fenol dimana akan terlihat dari hasil optimasi suhu dan waktu yang digunakan dalam proses ekstraksi simplisia rimpang jahe merah. Ekstraksi dilakukan dengan metode refluks dengan menggunakan pelarut etanol 96% dan variasi suhu yaitu 50˚c, 60˚c, 70˚c dan 80˚c, dan lama waktu 30, 60, 90, dan 120 menit. Dan hasil dari optimasi suhu dan waktu ekstraksi yang menunjukkan hasil kadar total flavonoid dan fenol. Hasil dari proses ekstraksi yang menunjukkan % rendemen paling tinggi pada suhu 70˚c dan waktu 90 menit. Hasil dari kadar total flavonoid dan kadar total fenol terendah berbanding lurus dengan pengaruh waktu dan suhu selama ekstraksi. Hasil kadar flavonoid yaitu 0,54 gQE/100g, dan hasil kadar fenol yaitu 28,83 gGAE/100g. --- Red ginger rhizome (Zingiber officinale Roscoe var. Rubrum) is a plant that has many uses, apart from being one of the plants used for cooking, this plant is also used traditionally in medicine and has become one of the types of raw materials in making herbal medicine in Indonesia. According to several studies, red ginger rhizome contains flavonoids and pilifenols, one of which is gingerol. Therefore, the aim of this study is to determine the total levels of flavonoid and phenol compounds which will be seen from the results of temperature and time optimization used in the extraction process of red ginger rhizome simplicia. Extraction was carried out by reflux method using 96% ethanol solvent and temperature variations, namely 50˚c, 60˚c, 70˚c and 80˚c, and duration of 30, 60, 90, and 120 minutes. And the results of the optimization of temperature and extraction time showed the results of total levels of flavonoids and phenols. The results of the extraction process showed the highest% yield at a temperature of 70˚c and 90 minutes. The results of the extraction process showed the highest% yield at a temperature of 70˚c and time of 90 minutes. The results of the total flavonoid content and the lowest total phenol content were directly proportional to the effect of time and temperature during extraction. The results of flavonoid levels were 0.54 gQE / 100g, and the results of phenol levels were 28.83 gGAE / 100g.
