Efek kesehatan dari ekstrak klorofil untuk suplementasi penyakit diabetes tipe 2 sebagian besar telah diteliti selama beberapa tahun terakhir. Namun, sumber klorofil belum dievaluasi secara ekstensif. Tujuan dari penelitian ini adalah untuk menyelidiki potensi penggunaan dua mikroalga berbeda, Chlorella vulgaris dan Spirulina platensis yang mudah ditemukan di lingkungan sebagai sumber dari ekstrak klorofil dengan daun bayam sebagai pembanding. Dalam studi ini, para vulgaris mikroalga Chlorella vulgaris dan Spirulina platensis dibudidayakan di fotobioreaktor pelat datar volume 6 liter selama 1 bulan, diendapkan dan dikeringkan pada suhu kamar. Daun bayam dibeli di supermarket lokal, dikeringkan pada suhu kamar, dan dihancurkan oleh blender. Setiap biomassa kering kemudian diekstraksi dengan tiga pelarut yang berbeda: 96% Etanol, Aseton dan Kloroform secara terpisah, disentrifugasi, dan supernatan diukur dalam Spectrophotometer untuk kuantifikasi klorofil. Pengaruh Waktu Homogenisasi juga diselidiki. Dalam rentang waktu 0, 45, 90, 135, dan 180 menit. Chlorella vulgaris memiliki ekstrak klorofil tertinggi dengan kloroform dengan 7944,35 µg klorofil / g biomassa, di mana Spirulina platensis dan bayam daun memiliki ekstrak klorofil tertinggi dengan aseton, dengan hasil 3.506,63 µg klorofil / g biomassa dan 6676,23 µg klorofil / g biomassa, berturut-turut. Waktu Homogenisasi yang optimal untuk Chlorella vulgaris, Spirulina platensis dan daun bayam adalah 90, 45 dan 90 menit, berturut-turut. Kesimpulannya, dibandingkan dengan daun bayam, Chlorella vulgaris dan Spirulina platensis memiliki potensi sumber baru ekstrak klorofil untuk suplementasi penyakit diabetes tipe 2.

The health effect of the chlorophyll extract for the diabetes type 2 disease supplementation has been largely investigated for the past few years. However, the source of chlorophyll has not been evaluated extensively. The aim of this study is to investigate the potential use of two different microalgae, Chlorella vulgaris and Spirulina platensis that easily found in the environment as the source of the chlorophyll extract with the spinach leaf as the comparison. In this study, the microalgae Chlorella vulgaris and Spirulina platensis was cultivated in 6 liters? volume flat plate photobioreactor for 1 months, precipitated and dried at the room temperature. The spinach leaf was purchased on local supermarket, dried at the room temperature, and crushed by the blender. Each dried biomass then extracted with three different solvents: 96% Ethanol, Acetone and Chloroform separately, centrifuged, and the supernatant was measured in Spectrophotometer for chlorophyll quantification. The effect of the extraction time also investigated at 0, 45, 90, 135 and 180 minutes. Chlorella vulgaris has the highest chlorophyll extract with chloroform with 7944.35 µg chlorophyll/g biomass, where Spirulina platensis and spinach leaf has the highest chlorophyll extract with acetone, with the result of 3506.63 µg chlorophyll/g biomass and 6676.23 µg chlorophyll/g biomass, consecutively. The optimum extraction time for Chlorella vulgaris, Spirulina platensis and spinach leaf was 90, 45 and 90 minutes, consecutively. In conclusion, compared with the spinach leaf, Chlorella vulgaris and Spirulina platensis has the potential for the new source of chlorophyll extract for the diabetes type 2 disease supplementation.

Prevention of type 2 diabetes can be achieved properly by simultaneous prevention of obesity. Prediabetes, or metabolic syndrome, is the period between simple obesity and diabetes, and this critical period needs to be identified in a more consistent and systematic manner by clinicians worldwide. Clinical trials have indicated that diabetes prevention can be achieved by lifestyle changes and also by certain medications, though none are yet approved for use in prevention. On the other hand, there are funding agencies such as the NIH, CDC, and state institutions that are interested in studying the prevention paradigms in different communities and ethnic minorities who are most prone to this epidemic. For these reasons, this title by renowned physician-scientist Derek LeRoith is both timely and vitally important for academic physicians, practitioners, allied health care providers, analysts, community activists, and all others interested in this increasing epidemic. This book provides a unique and comprehensive synthesis of the prevention and early diagnosis of Type 2 Diabetes, focusing on identifying risk factors and then moving into topics that address how to prevent their progression to full-blown diabetes. The difficult task of changing patients’ behavior is given special emphasis. The chapters in this practical volume are written by a wide range of international experts, reflecting the editor’s distinguished, internationally renowned career. The volume is organized in eight sections: an introduction to the overall issue of prevention, definitions of values based on ADA guidelines, pathophysiology, discussion of a range of interventional trials regarding prevention, and an overview of state-of-the-art clinical management approaches.
