Tumbuhan nipah (Nypa fruticans) merupakan tumbuhan air yang mengandung senyawa polifenol dan dimanfaatkan sebagai antioksidan alami. Proses ekstraksi menghasilkan ekstrak kasar yang masih terdapat senyawa pengotor sehingga perlu dilakukan purifikasi. Purifikasi merupakan proses pemisahan komponen bioaktif yang diinginkan dengan senyawa pengotor. Penelitian ini bertujuan untuk mengetahui pengaru…
Nipah (Nypa fruticans) merupakan palma mangrove yang mengandung senyawa polifenol. Senyawa polifenol berpotensi sebagai antioksidan karena kemampuannya dalam menyumbang atom hidrogen. Kandungan polifenol dipengaruhi oleh tingkat kematangan buah. Parameter yang diamati meliputi rendemen, total fenol, total tanin, total flavonoid, aktivitas antioksidan, dan analisis gugus fungsi FT-IR. Hasil menu…
This study aims to determine the effect of ethanol concentration on the levels of polyphenols, flavonoids and tannins as well as the antioxidant activity of nipah (Nypa fruticans) husk extract produced. This study was conducted experimentally in the laboratory with ethanol concentration treatment consisting of 4 levels (concentrations of 50%, 60%, 70% and 80%) and repeated 3 times. The paramete…
BERNICA TOYBA, Antihipercolesterolemia Activity Of Nipah (Nypa fruticans) Fiber Extract With Different Extraction Temperature (Supervised by SABRI SUDIRMAN). Hypercholesterolemia is a condition of increased LDL-cholesterol and triglyceride levels and decreased HDL-cholesterol levels, which is generally treated with drugs such as simvastatin. The purpose of this study was to determine the effect…
This study aims to characterize the properties of nypa fruit (Nypa fruticans Wurmb) starch by using different methods of starch isolation. The starch isolation method used are Water Steeping (WS) which is immersion in water and Alkaline Steeping (AS) which is immersion in alkaline. It is expected to get the best results from the differences in the isolation method carried out on the starch prop…
